 ## Installation
 
 To install the latest stable release, run the following commands as a user who has access to `sudo`:
 
 ```shell
-wget https://raw.githubusercontent.com/dokku/dokku/v0.10.0/bootstrap.sh
-sudo DOKKU_TAG=v0.10.0 bash bootstrap.sh
+wget https://raw.githubusercontent.com/dokku/dokku/v0.20.0/bootstrap.sh
+sudo DOKKU_TAG=v0.20.0 bash bootstrap.sh
 ```
 
 You can then proceed to the ip address or domain name associated with your server to complete the web-based installation.

+Sometimes you need to run a command on at deployment time, but before an app is completely deployed. Common use cases include:
 
 * Checking a database is initialized
 * Running database migrations
 * Any commands required to set up the server (e.g. something like a Django `collectstatic`)
 
-## `app.json` and `scripts.dokku`
+To support this, Dokku provides support for a special `release` command within your app's `Procfile`, as well as a special `scripts.dokku` key inside of your app's `app.json` file. Be aware that all commands are run within the context of the built docker image - no commands affect the host unless there are volume mounts attached to your app.
 
-Dokku accomplishes this by using an `app.json` file. The format in use is similar to format of Heroku's [app.json](https://devcenter.heroku.com/articles/app-json-schema).
-However, Dokku currently only supports the nodes `scripts.dokku.predeploy` and `scripts.dokku.postdeploy`.
-For buildpack apps, simply place an `app.json` file in the root of your repository.
-For dockerfile apps, place `app.json` in the configured `WORKDIR` directory; otherwise Dokku defaults to the buildpack app behavior of looking in `/app`.
+Each "phase" has different expectations and limitations:
 
-> NOTE: postdeploy changes are *NOT* committed to the app image.
+- `app.json`: `scripts.dokku.predeploy`
+    - When to use: This should be used if your app does not support arbitrary build commands and you need to make changes to the built image.
+    - Are changes committed to the image at this phase: Yes
+    - Example use-cases
+        - Bundling assets in a slightly different way
+        - Installing a custom package from source or copying a binary into place
+- `app.json`: `scripts.dokku.postdeploy`
+    - When to use: This should be used in conjunction with external systems to signal the completion of your deploy.
+    - Are changes committed to the image at this phase: No
+    - Example use-cases
+        - Notifying slack that your app is deployed
+        - Coordinating traffic routing with a central load balancer
+- `Procfile`: `release`
+    - When to use: This should be used in conjunction with external systems to signal the completion of your app image build.
+    - Are changes committed to the image at this phase: No
+    - Example use-cases
+        - Sending CSS, JS, and other assets from your app’s slug to a CDN or S3 bucket
+        - Priming or invalidating cache stores
+        - Running database migrations
 
-### Example app.json
+Please keep the above in mind when utilizing deployment tasks.
 
-> NOTE: Only the `scripts.dokku.predeploy` and `scripts.dokku.postdeploy` tasks are supported by Dokku at this time. All other fields will be ignored and can be omitted.
+> To execute commands on the host during a release phase, see the [plugin creation documentation](/docs/development/plugin-creation.md) docs for more information on building your own custom plugin.
+
+## `app.json` deployment tasks
+
+Dokku provides limited support for the `app.json` manifest from Heroku (documentation available [here](https://devcenter.heroku.com/articles/app-json-schema)). The keys available for use with Deployment Tasks are:
+
+- `scripts.dokku.predeploy`: This is run _after_ an app's docker image is built, but _before_ any containers are scheduled. Changes made to your image are committed at this phase.
+- `scripts.dokku.postdeploy`: This is run _after_ an app's containers are scheduled. Changes made to your image are *not* committed at this phase.
+
+For buildpack-based deployments, the location of the `app.json` file should be at the root of your repository. Dockerfile-based app deploys should have the `app.json` in the configured `WORKDIR` directory; otherwise Dokku defaults to the buildpack app behavior of looking in `/app`.
+
+> Warning: Any failed `app.json` deployment task will fail the deploy. In the case of either phase, a failure will not affect any running containers.
+
+The following is an example `app.json` file. Please note that only the `scripts.dokku.predeploy` and `scripts.dokku.postdeploy` tasks are supported by Dokku at this time. All other fields will be ignored and can be omitted.

+## Procfile Release command
+
+> New as of 0.14.0
+
+The `Procfile` also supports a special `release` command which acts in a similar way to the [Heroku Release Phase](https://devcenter.heroku.com/articles/release-phase). This command is executed _after_ an app's docker image is built, but _before_ any containers are scheduled. This is also run _after_ any command executed by `scripts.dokku.predeploy`.
+
+To use the `release` command, simply add a `release` stanza to your Procfile.
+
+```Procfile
+release: curl https://some.external.api.service.com/deployment?state=built
+```
+
+Unlike the `scripts.dokku.predeploy` command, changes made during by the `release` command are *not* persisted to disk.
+
+> Warning: scaling the release command up will likely result in unspecified issues within your deployment, and is highly discouraged.

 > The storage plugin is compatible with storage mounts created with the docker-options. The storage plugin will only list mounts from the deploy/run phase.
 
-## Ideology and Background
+The storage plugin supports the following mount points:
 
-The storage plugin requires explicit paths on the host side. This is intentional to ensure that new users avoid running into unexpected results with implicit paths that may not exist (a feature deprecated in [Docker 1.9.0](https://github.com/docker/docker/releases/tag/v1.9.0])). The container directory is created for the mount point in the container. Any existing directory contents are not accessible after a mount is added to the container. Dokku creates a new directory `/var/lib/dokku/data/storage` during installation, it's the general consensus that new users should use this directory. Mounts are only available at run and deploy times, you must redeploy (restart) an app to mount or unmount to an existing app's container.
+- explicit paths that exist on the host
+- docker volumes
+
+There are a few caveats to using the persistent storage plugin:
+
+- Using implicit paths that do not exist are no longer supported, and actually deprecated in [Docker 1.9.0](https://github.com/docker/docker/releases/tag/v1.9.0). When you specify a persistent storage mount, the host directory is **not** autocreated by either Dokku or Docker.
+- We recommend using the directory `/var/lib/dokku/data/storage` directory as the root host path for mounts, and we create this on Dokku installation.
+- Mounts are only available at run and deploy times, and you **must** redeploy (restart) an app to mount or unmount to an existing app's container.
+- When a directory is mounted, any existing files within the container will be overwritten. If you are writing assets during the build process and then replace the directory with a mount, those files will no longer exist. This is a Docker limitation.
+- Paths are mounted within the container at the root of the disk - `/` - and are **not** relative to `/app` (for buildpacks deploys) or the `WORKDIR` (for Dockerfile/Docker images).
+- For applications using buildpack deploys, the host directory should be owned by the user and group id `32767`. This is due to how permissions within Herokuish - which builds the Docker images - works. For Dockerfile or Docker image deployments, please use the user and group id which corresponds to the one running the process within the container.

-In Dokku 0.5.0, port proxying was decoupled from the `nginx-vhosts` plugin into the proxy plugin. Dokku 0.6.0 introduced the ability to map host ports to specific container ports. In the future this will allow other proxy software - such as HAProxy or Caddy - to be used in place of nginx.
-
-## Usage
-
-### Container network interface binding
-
-> New as of 0.5.0
-
-By default, the deployed docker container running your app's web process will bind to the internal docker network interface (i.e. `docker inspect --format '{{ .NetworkSettings.IPAddress }}' $CONTAINER_ID`). This behavior can be modified per app by disabling the proxy (i.e. `dokku proxy:disable <app>`). In this case, the container will bind to an external interface (i.e. `0.0.0.0`) and your app container will be directly accessible by other hosts on your network.
-
-> If a proxy is disabled, Dokku will bind your container's port to a random port on the host for every deploy, e.g. `0.0.0.0:32771->5000/tcp`.
-
-By way of example, in the default case, each container is bound to the docker interface:
-
-```shell
-docker ps
-```
-
-```
-CONTAINER ID        IMAGE                      COMMAND                CREATED              STATUS              PORTS               NAMES
-1b88d8aec3d1        dokku/node-js-app:latest   "/bin/bash -c '/star   About a minute ago   Up About a minute                       node-js-app.web.1
-```
-
-As such, the container's IP address will be an internal IP, and thus it is only accessible on the host itself:
-
-```
-docker inspect --format '{{ .NetworkSettings.IPAddress }}' node-js-app.web.1
-```
-
-```
-172.17.0.6
-```
-
-However, you can disable the internal proxying via the `proxy:disable` command so that it will listen on the host's IP address:
-
-```shell
-dokku proxy:disable node-js-app
-
-# container bound to all interfaces
-docker ps
-```
-
-```
-CONTAINER ID        IMAGE                      COMMAND                CREATED              STATUS              PORTS                     NAMES

-```
-
-You can pass flags which will output only the value of the specific information you want. For example:
-
-```shell
-dokku proxy:report node-js-app --proxy-type
-```
-
-### Proxy port mapping
-
-> New as of 0.6.0
-
-You can now configure `host -> container` port mappings with the `proxy:ports-*` commands. This mapping is currently supported by the built-in nginx-vhosts plugin.
-
-To inspect the port mapping for a given application, use the `proxy:ports` command:
-
-```shell
-dokku proxy:ports node-js-app
-```
-
-```
------> Port mappings for node-js-app
------> scheme             host port                 container port
-http                      80                        5000
-```
-
-The above application is listening on the host's port `80`, which we can test via curl:
-
-```shell
-curl http://node-js-app.dokku.me
-```
-
-```
-Hello World!
-```
-
-There are cases where we may wish for the service to be listening on more than one port, such as port 8080. Normally, this would not be possible:
-
-```shell
-curl http://node-js-app.dokku.me:8080
-```
-
-```
-curl: (7) Failed to connect to node-js-app.dokku.me port 8080: Connection refused
-```
-
-However, we can use the `proxy:ports-add` command to add a second external port mapping - `8080` - to our application's port `5000`.
-
-```shell
-dokku proxy:ports-add node-js-app http:8080:5000
-```
-
-```
------> Setting config vars
-       DOKKU_PROXY_PORT_MAP: http:80:5000 http:8080:5000
------> Configuring node-js-app.dokku.me...(using built-in template)
------> Creating http nginx.conf
------> Running nginx-pre-reload
-       Reloading nginx
-```
-
-We can now test that port 80 still responds properly:
-
-```shell
-curl http://node-js-app.dokku.me
-```
-
-```
-Hello World!
-```
-
-And our new listening port of `8080` also works:
-
-```shell
-curl http://node-js-app.dokku.me:8080
-```
-
-```
-Hello World!
-```
-
-You can also remove a port mapping that is no longer necessary:
-
-```shell
-dokku proxy:ports-remove node-js-app http:80:5000
-```
-
-By default, buildpack apps and dockerfile apps **without** explicitly exposed ports (i.e. using the `EXPOSE` directive) will be configured with a listener on port `80` (and additionally a listener on 443 if ssl is enabled) that will proxy to the application container on port `5000`. Dockerfile apps **with** explicitly exposed ports will be configured with a listener on each exposed port and will proxy to that same port of the deployed application container.
-
-> Note: This default behavior **will not** be automatically changed on subsequent pushes and must be manipulated with the `proxy:ports-*` syntax detailed above.
-
-#### Proxy Port Scheme
-
-The proxy port scheme is as follows:
-
-- `SCHEME:HOST_PORT:CONTAINER_PORT`
-
-The scheme metadata can be used by proxy implementations in order to properly handle proxying of requests. For example, the built-in `nginx-vhosts` proxy implementation supports both the `http` and `https` schemes.
-
-Developers of proxy implementations are encouraged to use whatever schemes make the most sense, and ignore configurations which they do not support. For instance, a `udp` proxy implementation can safely ignore `http` and `https` port mappings.
-
-To change the proxy implementation in use for an application, use the `proxy:set` command:
-
-```shell
-# no validation will be performed against
-# the specified proxy implementation
-dokku proxy:set node-js-app nginx
-```

+resource:reserve-clear [--process-type <process-type>] <app>               # Reserve resources for a given app/process-type combination
+```
+
+The resource plugin is meant to allow users to limit or reserve resources for a given app/process-type combination.
+
+## Usage
+
+By default, Dokku allows unlimited resource access to apps deployed on a server. In some cases, it may be desirable to limit this on a per-app or per-process-type basis. The `resource` plugin allows management of both resource "limits" and resource "reservations", where each resource request type has specific meaning to the scheduler in use for a given app.
+
+> The meaning of a values and it's units are specific to the scheduler in use for a given app. If a scheduler does not support a given resource type combination, it will be ignored. All resource commands require an app rebuild or deploy in order to take effect.
+
+Valid resource options include:
+
+- `--cpu`
+- `--memory`
+- `--memory-swap`
+- `--network`
+- `--network-ingress`
+- `--network-egress`
+
+See the [Supported Resource Management Properties](/docs/advanced-usage/schedulers/docker-local.md#supported-resource-management-properties) section of the docker local scheduler documentation for more information on how each resource limit maps to Docker.
+
+Resource limits and reservations are applied only during the `run` and `deploy` phases of an application, and will not impact the `build` phase of an application.
+
+### Resource Limits
+
+When specified and supported, a resource limit will ensure that your app does not go _over_ the specified value. If this occurs, the underlying scheduler may either cap resource utilization, or it may decide to terminate and reschedule your process.
+
+Resource limits may be set via the `resource:limit` command:
+
+```shell
+dokku resource:limit --memory 100 node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app
+       memory: 100
+```
+
+Multiple resources can be limited in a single call:
+
+```shell
+dokku resource:limit --cpu 100 --memory 100 node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app
+       cpu: 100
+       memory: 100
+```
+
+Resources can also be limited on a per-process type basis. If specified, this will override any generic limits set for the app.
+
+```shell
+dokku resource:limit --cpu 100 --memory 100 --process-type worker node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app (worker)
+       cpu: 100
+       memory: 100
+```
+
+#### Displaying Resource Limits
+
+Running the `resource:limit` command without any flags will display the currently configured default app limits.
+
+```shell
+dokku resource:limit node-js-app
+```
+
+```
+=====> resource limits node-js-app information [defaults]
+       cpu:
+       memory:
+       memory-swap: 100
+       network: 100
+       network-ingress:
+       network-egress:
+```
+
+This may also be combined with the `--process-type` flag to see app limits on a process-type level. Note that the displayed values are not merged with the defaults.
+
+
+```shell
+dokku resource:limit --process-type web node-js-app
+```
+
+```
+=====> resource limits node-js-app information (web)
+       cpu: 100
+       memory: 100
+       memory-swap:
+       network:
+       network-ingress:
+       network-egress:
+```
+
+#### Clearing Resource Limits
+
+In cases where the values are incorrect - or there is no desire to limit resources - resource limits may be cleared using the `resource:limit-clear` command.
+
+```shell
+dokku resource:limit-clear node-js-app
+```
+
+```
+-----> Clearing resource limit for node-js-app
+```
+
+Defaults can also be cleared by leaving the app unspecified.
+
+```shell
+dokku resource:limit-clear
+```
+
+```
+-----> Clearing default resource limits
+```
+
+### Resource Reservations
+
+When specified and supported, a resource reservation will ensure that your server has _at least_ the specified resources before placing a given app's process. If there a resource exhaustion, future rebuilds and deploys may fail.
+
+Resource reservations may be set via the `resource:reserve` command:
+
+```shell
+dokku resource:reserve --memory 100 node-js-app
+```
+
+```
+=====> Setting resource reservation for node-js-app
+       memory: 100
+```
+
+Multiple resources can be limited in a single call:
+
+```shell
+dokku resource:reserve --cpu 100 --memory 100 node-js-app
+```
+
+```
+=====> Setting resource reservation for node-js-app
+       cpu: 100
+       memory: 100
+```
+
+Resources can also be limited on a per-process type basis. If specified, this will override any generic limits set for the app.
+
+```shell
+dokku resource:reserve --cpu 100 --memory 100 --process-type worker node-js-app
+```
+
+```
+=====> Setting resource reservation for node-js-app (worker)
+       cpu: 100
+       memory: 100
+```
+
+#### Displaying Resource Reservations
+
+Running the `resource:reserve` command without any flags will display the currently configured default app reservations.
+
+```shell
+dokku resource:reserve node-js-app
+```
+
+```
+=====> resource reservation node-js-app information [defaults]
+       cpu: 100

+       memory-swap:
+       network:
+       network-ingress:
+       network-egress:
+```
+
+This may also be combined with the `--process-type` flag to see app reservations on a process-type level. Note that the displayed values are not merged with the defaults.
+
+```shell
+dokku resource:reserve --process-type web node-js-app
+```
+
+```
+=====> resource reservation node-js-app information (web)
+       cpu: 100
+       memory: 100
+       memory-swap:
+       network:
+       network-ingress:
+       network-egress:
+```
+
+#### Clearing Resource Reservations
+
+In cases where the values are incorrect - or there is no desire to reserve resources - resource reservations may be cleared using the `resource:reserve-clear` command.
+
+```shell
+dokku resource:reserve-clear node-js-app
+```
+
+```
+-----> Clearing resource reservation for node-js-app
+```
+
+Defaults can also be cleared by leaving the app unspecified.
+
+```shell
+dokku resource:reserve-clear
+```
+
+```
+-----> Clearing default resource reservation
+```
+
+### Displaying resource reports for an app
+
+You can get a report about the app's resource status using the `resource:report` command:
+
+```shell
+dokku resource:report
+```
+
+```

+```
+
+> New as of 0.12.0
+
+Dokku natively includes functionality to manage application lifecycles for a single server using the `scheduler-docker-local` plugin. It is the default scheduler, but as with all schedulers, it is set on a per-application basis. The scheduler can currently be overridden by running the following command:
+
+```shell
+dokku config:set node-js-app DOCKER_SCHEDULER=docker-local
+```
+
+As it is the default, unsetting the `DOCKER_SCHEDULER` config variable is also a valid way to reset the scheduler.
+
+```shell
+dokku config:unset node-js-app DOCKER_SCHEDULER
+```
+
+## Usage
+
+### Disabling chown of persistent storage
+
+The `scheduler-docker-local` plugin will ensure your storage mounts are owned by either `herokuishuser` or the overridden value you have set in `DOKKU_APP_USER`. You may disable this by running the following `scheduler-docker-local:set` command for your application:
+
+```shell
+dokku scheduler-docker-local:set node-js-app disable-chown true
+```
+
+Once set, you may re-enable it by setting a blank value for `disable-chown`:
+
+```shell
+dokku scheduler-docker-local:set node-js-app disable-chown
+```
+
+## Implemented Triggers
+
+This plugin implements various functionality through `plugn` triggers to integrate with Docker for running apps on a single server. The following functionality is supported by the `scheduler-docker-local` plugin.
+
+- `check-deploy`
+- `core-post-deploy`
+- `post-app-clone-setup`
+- `post-create`
+- `post-delete`
+- `pre-deploy`
+- `pre-restore`
+- `scheduler-deploy`
+- `scheduler-docker-cleanup`
+- `scheduler-inspect`
+- `scheduler-logs-failed`
+- `scheduler-logs`
+- `scheduler-retire`
+- `scheduler-run`
+- `scheduler-stop`
+- `scheduler-tags-create`
+- `scheduler-tags-destroy`
+
+## Supported Resource Management Properties
+
+The `docker-local` scheduler supports a minimal list of resource _limits_ and _reservations_. The following properties are supported:
+
+### Resource Limits
+
+- cpu: (docker option: `--cpus`), and is specified in number of CPUs a process can access.
+  - See the ["CPU" section](https://docs.docker.com/config/containers/resource_constraints/#cpu) of the Docker Runtime Options documentation for more information.
+- memory: (docker option: `--memory`) and should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes).
+  - See the ["Memory" section](https://docs.docker.com/config/containers/resource_constraints/#memory) of the Docker Runtime Options documentation for more information.
+- memory-swap: (docker option: `--memory-swap`) and should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes)
+  - See the ["Memory" section](https://docs.docker.com/config/containers/resource_constraints/#memory) of the Docker Runtime Options documentation for more information.
+
+### Resource Reservations
+

+# 0.20.0 Migration Guide
+
+## Removals
+
+### Command removals
+
+The following commands were previously deprecated and were removed in this release.
+
+- `apps`: Use `apps:list` instead.
+- `certs`: Use `certs:report` instead.
+- `certs:info`: Use `certs:report` instead.
+- `checks`: Use `checks:report` instead.
+- `docker-options`: Use `docker-options:report` instead.
+- `domains`: Use `domains:report` instead.
+- `plugin`: Use `plugin:list` instead.
+- `proxy`: Use `proxy:report` instead.
+- `trace`: Use `trace:on` or `trace:off` instead.
+- `ps`: Use `enter` with a container ID instead to run `ps auxww` within a container.
+
+The refactor of the proxy plugin removes the following functions from being sourced in plugins:
+
+- `proxy#get_app_proxy_port_map()`
+- `proxy#list_app_proxy_ports()`
+- `proxy#filter_app_proxy_ports()`
+- `proxy#add_proxy_ports()`
+- `proxy#remove_proxy_ports()`
+- `proxy#set_proxy_ports()`
+
+The informal policy is to allow removal of functions within a `functions` file if they are not used in OSS plugins. Should you be affected by any such removals, please file an issue to expose the functionality via a plugin trigger.
+
+### Remove support for Unsupported Operating Systems
+
+Dokku will no longer distribute packages for Ubuntu versions that have reached either End of Life or End of Standard Support (for LTS releases). This currently includes the following releases:
+
+- Ubuntu 14.04 (trusty)
+- Ubuntu 14.10 (utopic)
+- Ubuntu 15.04 (vivid)
+- Ubuntu 15.10 (wily)
+- Ubuntu 16.10 (yakkety)
+- Ubuntu 17.04 (zesty)
+- Ubuntu 17.10 (artful)
+
+Dokku will no longer distribute packages for Debian versions that are not `stable` or `oldstable`. This currently includes the following releases:
+
+- Debian 7 (wheezy)
+- Debian 8 (jessie)
+
+### App report flags
+
+The `--git-sha` flag was moved from the `apps:report` command to the `git:report` command.
+
+## Changes
+
+### App report flags
+
+The following changes on the `apps:report` command were made in this release:
+
+- The `--deploy-source` flag was renamed to `--app-deploy-source`.
+- The `--locked` flag was renamed to `--app-locked`.
+
+### Network report flags
+
+The following changes on the `network:report` command were made in this release:
+
+- The `--network-listeners` flag was renamed to `--network-web-listeners`.
+
+### Plugin Triggers
+
+- The `network-get-port` trigger was incorrectly documented to have the `isHerokuishContainer` argument as the third argument. The code has been fixed to respect the documentation.
+- The `network-get-listeners` trigger now takes an additional `processType` argument. If not specified, it defaults to `web`. This default will be removed in an upcoming release.
+
+## Deprecations
+
+- `nginx:show-conf` has been deprecated in favor of `nginx:show-config`.
+- `proxy#is_app_proxy_enabled()` is deprecated in favor of `plugn trigger proxy-is-enabled`.
+- `proxy#get_app_proxy_type()` is deprecated in favor of `plugn trigger proxy-type`.
+- `apps#apps_create()` is deprecated in favor of `plugn trigger app-create`.
+- `apps#apps_destroy()` is deprecated in favor of `plugn trigger app-destroy`.
+- `apps#apps_exists()` is deprecated in favor of `plugn trigger app-exists`.
+- `apps#apps_maybe_create()` is deprecated in favor of `plugn trigger app-maybe-create`.
+- `plugin trigger network-get-listeners` usage without a second `processType` argument is deprecated.
+- `.NGINX_PORT` variable usage within `nginx.conf.sigil` templates is deprecated in favor of `.PROXY_PORT`.
+- `.NGINX_SSL_PORT` variable usage within `nginx.conf.sigil` templates is deprecated in favor of `.PROXY_SSL_PORT`.
+- `.DOKKU_APP_LISTENERS` variable usage within `nginx.conf.sigil` templates is deprecated in favor of `.DOKKU_APP_WEB_LISTENERS`.

+# Deploying with Gitlab CI
+
+Gitlab-CI can be used to automatically deploy a Dokku application using the [ilyasemenov/gitlab-ci-git-push image](https://github.com/IlyaSemenov/gitlab-ci-git-push) docker image.
+
+## Prerequisites
+
+Make sure you have a Gitlab account and a Dokku project hosted on Gitlab. This method works whether if you are using buildpacks or Dockerfile.
+
+Make sure you have set up an app on the remote machine following [these instructions](http://dokku.viewdocs.io/dokku/deployment/application-deployment/) and can successfully deploy to it from the local machine.
+
+## Deploy automatically to production
+
+### Add a secret variable
+
+Browse to the repository in question and visit the following path: `the Gitlab project > Settings > CI/CD.`
+
+Click on `Secret variables > Expand` and fill in the blanks.
+
+- Key: `SSH_PRIVATE_KEY`
+- Value: paste in an SSH private key registered in Dokku:
+
+    -----BEGIN RSA PRIVATE KEY-----
+    ...
+    -----END RSA PRIVATE KEY-----
+
+- Environment scope: `production` (This make sure that `SSH_PRIVATE_KEY` is not available on merge requests or tests)
+- Protected: Do not check this checkbox unless you know what you are doing
+
+### Add CI script
+
+Create a file named `.gitlab-ci.yml` at the root directory of the repository with the following contents:
+
+```yaml
+stages:
+  - deploy
+
+variables:
+  APP_NAME: node-js-app
+
+deploy:
+  image: ilyasemenov/gitlab-ci-git-push
+  stage: deploy
+  environment:
+    name: production
+    url: https://$APP_NAME.dokku.me/
+  only:
+    - master
+  script:
+    - git-push ssh://dokku@dokku.me:22/$APP_NAME
+```
+
+You will need to modify the `APP_NAME` variable to the correct value for your application name.
+
+Running `git push origin master` will now trigger a gitlab-ci pipeline that will automatically deploy your application to your Dokku server. Go to your project on Gitlab and visit "Project > Pipelines" to see the deployment log.
+
+
+## Review Applications
+
+One useful feature of gitlab is to be able to create review applications for non-production branches. This allows teams to review changes _before_ they are pushed to production. First, recreate the `SSH_PRIVATE_KEY` secret - do not delete the existing secret - but scoped to the `review/*` environment. This will allow non-production gitlab environments access to the secret.
+
+Next, we'll need to create the `review_app` gitlab job in our `.gitlab-ci.yaml`.
+
+```yaml
+review_app:
+  image: ilyasemenov/gitlab-ci-git-push
+  stage: deploy
+  environment:
+    name: review/$CI_COMMIT_REF_NAME
+    url: https://$CI_ENVIRONMENT_SLUG.dokku.me/
+    on_stop: stop_review_app
+  only:
+    - branches
+  except:
+    - master
+  script:
+    - mkdir -p ~/.ssh && echo "$SSH_PRIVATE_KEY" | tr -d '\r' > ~/.ssh/id_rsa && chmod 600 ~/.ssh/id_rsa
+    - ssh-keyscan -H 22 "dokku.me" >> ~/.ssh/known_hosts
+    - ssh -t dokku@dokku.me -- apps:clone --ignore-existing --skip-deploy "$APP_NAME" "$CI_ENVIRONMENT_SLUG"
+    - git-push ssh://dokku@dokku.me:22/$CI_ENVIRONMENT_SLUG
+```
+
+The first two lines ensure that Gitlab can talk to the Dokku server. Next, we take advantage of the `apps:clone` command, and clone the existing application and all of it's configuration to a new location. If the new application already exists, the third line of the `script` step will be ignored. We also ignore the first deploy script to speed up the cloning process. Finally, the fourth line of the `script` step will deploy the code as normal.
+
+The above only runs for non-master branches, and will _also_ trigger an `on_stop` job called `stop_review_app`. When the branch is deleted or the code is merged, the `stop_review_app` job will be triggered.
+
+```yaml
+stop_review_app:
+  image: ilyasemenov/gitlab-ci-git-push
+  stage: deploy
+  variables:
+    GIT_STRATEGY: none
+  environment:
+    name: review/$CI_COMMIT_REF_NAME
+    action: stop
+  when: manual
+  script:
+    - mkdir -p ~/.ssh && echo "$SSH_PRIVATE_KEY" | tr -d '\r' > ~/.ssh/id_rsa && chmod 600 ~/.ssh/id_rsa
+    - ssh-keyscan -H 22 "dokku.me" >> ~/.ssh/known_hosts
+    - ssh -t dokku@dokku.me -- --force apps:destroy "$CI_ENVIRONMENT_SLUG"
+```
+
+The `stop_review_app` step will delete the temporary application, cleaning up now unused server resources.
+
+Going further, the following modifications can be done:
+
+- Notify via chat whenever a review application is created/destroyed.
+- Push to a separate, staging server as opposed to a production server.
+- Clone a "staging" application so that review applications do not affect production datasets.

+# Run Dokku on External Volume
+
+In order to leverage cloud-provider facilities like _attachable volumes_, (_a.k.a. block storage_)
+the following is an easy tutorial to achieve Dokku runs on them.
+
+> Warning: If the block storage is not available and attached on boot it is possible that containers will not correctly start. Please keep this in mind when considering moving Dokku and/or Docker to network attached storage.
+
+## Tutorial
+
+The following is intended to be executed on the dokku host machine as `root`.
+Say, _for instance_, that our volume is mapped into the systems as `/dev/vdb1`.
+
+Stop docker daemon
+
+```shell
+systemctl stop docker
+```
+
+Prepare the filesystem:
+
+```shell
+mkfs -t ext4 /dev/vdb1
+mkdir /mnt/volume
+mount /dev/vdb1 /mnt/volume
+```
+
+Move the old data directories:
+
+```shell
+mv /home/dokku /home/dokku.OLD
+mv /var/lib/docker /var/lib/docker.OLD
+mv /var/lib/dokku /var/lib/dokku.OLD
+```
+
+Move the data on the volume
+
+```shell
+mkdir /mnt/volume/home/
+mkdir /mnt/volume/var/lib/
+mv /home/dokku.OLD /mnt/volume/home/dokku
+mv /var/lib/dokku.OLD /mnt/volume/var/lib/dokku
+mv /var/lib/docker.OLD /mnt/volume/var/lib/docker
+```
+
+Prepare the mountpoints
+
+```shell
+mkdir /home/dokku
+mkdir /var/lib/dokku
+mkdir /var/lib/docker
+chown dokku:dokku /home/dokku   # respect the original ownership
+chmod 711 /var/lib/docker       # respect the original permissions
+```
+
+Mount bind
+
+```shell
+mount -o bind /mnt/volume/home/dokku /home/dokku
+mount -o bind /mnt/volume/var/lib/dokku /var/lib/dokku
+mount -o bind /mnt/volume/var/lib/docker /var/lib/docker
+```
+
+Start docker daemon
+
+```shell
+systemctl start docker
+```
+
+At this point all should be working fine, please check it out.
+
+Then, let the changes be reboot-persistent
+
+```shell
+echo '/dev/vdb1 /mnt/volume ext4 defaults 0 2' | sudo tee -a /etc/fstab
+echo '/mnt/volume/home/dokku /home/dokku none defaults,bind 0 0' | sudo tee -a /etc/fstab
+echo '/mnt/volume/var/lib/dokku /var/lib/dokku none defaults,bind 0 0' | sudo tee -a /etc/fstab
+echo '/mnt/volume/var/lib/docker /var/lib/docker none defaults,bind 0 0' | sudo tee -a /etc/fstab

 ```
 
-On subsequent deploys, the nginx virtualhost will be discarded. This is useful when deploying internal-facing services that should not be publicly routeable. As of 0.4.0, nginx will still be configured to proxy your app on some random high port. This allows internal services to maintain the same port between deployments. You may change this port by setting `DOKKU_NGINX_PORT` and/or `DOKKU_NGINX_SSL_PORT` (for services configured to use SSL.)

+Environment variables are available both at run time and during the application build/compilation step for buildpack-based deploys.
 
 For buildpack deploys, Dokku will create a  `/app/.env` file that can be used for legacy buildpacks. Note that this is *not* updated when `config:set` or `config:unset` is called, and is only written during a `deploy` or `ps:rebuild`. Developers are encouraged to instead read from the application environment directly, as the proper values will be available then.

+
+## Binding to specific addresses
+
+> New as of 0.19.2
+
+By default, nginx will listen to all interfaces (`[::]` for IPv6, `0.0.0.0` for IPv4) when proxying requests to applications. This may be changed using the `bind-address-ipv4` and `bind-address-ipv6` properties. This is useful in cases where the proxying should be internal to a network or if there are multiple network interfaces that should respond with different content.
+
+```shell
+dokku nginx:set node-js-app bind-address-ipv4 127.0.0.1
+dokku nginx:set node-js-app bind-address-ipv6 ::1
+```
+
+This may be reverted by setting an empty bind address.
+
+```shell
+dokku nginx:set node-js-app bind-address-ipv4
+dokku nginx:set node-js-app bind-address-ipv6
+```
+
+> Warning: Validation is not performed on either value.
+
+Users with apps that contain a custom `nginx.conf.sigil` file will need to modify the files to respect the new `NGINX_BIND_ADDRESS_IPV4` and `NGINX_BIND_ADDRESS_IPV6` variables.
+
+## HSTS Header
+
+> New as of 0.20.0
+
+If SSL certificates are present, HSTS will be automatically enabled. It can be toggled via `nginx:set`:
+
+```shell
+dokku nginx:set node-js-app hsts true
+dokku nginx:set node-js-app hsts false
+```
+
+The following options are also available via the `nginx:set` command:
+
+- `hsts` (type: boolean, default: `true`): Enables or disables HSTS for your application.
+- `hsts-include-subdomains` (type: boolean, default: `true`): Tells the browser that the HSTS policy also applies to all subdomains of the current domain.
+- `hsts-max-age` (type: integer, default: `15724800`): Time in seconds to cache HSTS configuration.
+- `hsts-preload` (type: boolean, default: `false`): Tells most major web browsers to include the domain in their HSTS preload lists.
+
+Beware that if you enable the header and a subsequent deploy of your application results in an HTTP deploy (for whatever reason), the way the header works means that a browser will not attempt to request the HTTP version of your site if the HTTPS version fails until the max-age is reached.
+
+## Checking access logs
+
+You may check nginx access logs via the `nginx:access-logs` command. This assumes that app access logs are being stored in `/var/log/nginx/$APP-access.log`, as is the default in the generated `nginx.conf`.
+
+```shell
+dokku nginx:access-logs node-js-app
+```
+
+You may also follow the logs by specifying the `-t` flag.
+
+```shell
+dokku nginx:access-logs node-js-app -t
+```
+
+## Checking error logs
+
+You may check nginx error logs via the `nginx:access-logs` command. This assumes that app error logs are being stored in `/var/log/nginx/$APP-error.log`, as is the default in the generated `nginx.conf`.
+
+```shell
+dokku nginx:error-logs node-js-app
+```
+
+You may also follow the logs by specifying the `-t` flag.
+
+```shell
+dokku nginx:error-logs node-js-app -t
+```
+
+## Regenerating nginx config
+
+In certain cases, your app nginx configs may drift from the correct config for your app. You may regenerate the config at any point via the `nginx:build-config` command. This may fail if there are no current web listeners for your app.
+
+```shell
+dokku nginx:build-config node-js-app
+```
+
+## Showing the nginx config
+
+For debugging purposes, it may be useful to show the nginx config. This can be achieved via the `nginx:show-config` command.
+
+```shell
+dokku nginx:show-config node-js-app
+```
+
+## Validating nginx configs
+
+It may be desired to validate an nginx config outside of the deployment process. To do so, run the `nginx:validate-config` command. With no arguments, this will validate all app nginx configs, one at a time. A minimal wrapper nginx config is generated for each app's nginx config, upon which `nginx -t` will be run.
+
+```shell
+dokku nginx:validate-config
+```
+
+As app nginx configs are actually executed within a shared context, it is possible for an individual config to be invalid when being validated standalone but _also_ be valid within the global server context. As such, the exit code for the `nginx:validate-config` command is the exit code of `nginx -t` against the server's real nginx config.
+
+The `nginx:validate-config` command also takes an optional `--clean` flag. If specified, invalid nginx configs will be removed.
+
+> Warning: Invalid app nginx config's will be removed _even if_ the config is valid in the global server context.
+
+```shell
+dokku nginx:validate-config --clean
+```
+
+The `--clean` flag may also be specified for a given app:
+
+```shell
+dokku nginx:validate-config node-js-app --clean
 ```

 ### Customizing via configuration files included by the default templates
 
 The default nginx.conf template will include everything from your apps `nginx.conf.d/` subdirectory in the main `server {}` block (see above):
 
-```go
+```
 include {{ .DOKKU_ROOT }}/{{ .APP }}/nginx.conf.d/*.conf;
 ```
 
 That means you can put additional configuration in separate files, for example to limit the uploaded body size to 50 megabytes, do
 
 ```shell
-mkdir /home/dokku/myapp/nginx.conf.d/
-echo 'client_max_body_size 50M;' > /home/dokku/myapp/nginx.conf.d/upload.conf
-chown dokku:dokku /home/dokku/myapp/nginx.conf.d/upload.conf
+mkdir /home/dokku/node-js-app/nginx.conf.d/
+echo 'client_max_body_size 50m;' > /home/dokku/node-js-app/nginx.conf.d/upload.conf
+chown dokku:dokku /home/dokku/node-js-app/nginx.conf.d/upload.conf
 service nginx reload
 ```
 
-The example above uses additional configuration files directly on the Dokku host. Unlike the `nginx.conf.sigil` file, these additional files will not be copied over from your application repo, and thus need to be placed in the `/home/dokku/myapp/nginx.conf.d/` directory manually.
+The example above uses additional configuration files directly on the Dokku host. Unlike the `nginx.conf.sigil` file, these additional files will not be copied over from your application repo, and thus need to be placed in the `/home/dokku/node-js-app/nginx.conf.d/` directory manually.
+
+For PHP Buildpack users, you will also need to provide a `Procfile` and an accompanying `nginx.conf` file to customize the nginx config *within* the container. The following are example contents for your `Procfile`
+
+    web: vendor/bin/heroku-php-nginx -C nginx.conf -i php.ini php/
+    
+Your `nginx.conf` file - not to be confused with Dokku's `nginx.conf.sigil` - would also need to be configured as shown in this example:
+
+    client_max_body_size 50m;
+    location / {
+        index index.php;
+        try_files $uri $uri/ /index.php$is_args$args;
+    }
+
+Please adjust the `Procfile` and `nginx.conf` file as appropriate.
+
+## Custom Error Pages
+
+By default, Dokku provides custom error pages for the following three categories of errors:
+
+- 4xx: For all non-404 errors with a 4xx response code.
+- 404: For "404 Not Found" errors.
+- 5xx: For all 5xx error responses
+
+These are provided as an alternative to the generic Nginx error page, are shared for _all_ applications, and their contents are located on disk at `/var/lib/dokku/data/nginx-vhosts/dokku-errors`. To customize them for a specific app, create a custom `nginx.conf.sigil` as described above and change the paths to point elsewhere.

 ## HSTS Header
 
-The [HSTS header](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) is an HTTP header that can inform browsers that all requests to a given site should be made via HTTPS. Dokku does not, by default, enable this header. It is thus left up to you, the user, to enable it for your site.
+The [HSTS header](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) is an HTTP header that can inform browsers that all requests to a given site should be made via HTTPS. Dokku does not enables this header by default
 
-Beware that if you enable the header and a subsequent deploy of your application results in an HTTP deploy (for whatever reason), the way the header works means that a browser will not attempt to request the HTTP version of your site if the HTTPS version fails.
+See the [NGINX HSTS documentation](/docs/configuration/nginx.md#hsts-header) for more information.
+
+## HTTP/2 support
+
+Certain versions of nginx have bugs that prevent [HTTP/2](https://nginx.org/en/docs/http/ngx_http_v2_module.html) from properly responding to all clients, thus causing applications to be unavailable. For HTTP/2 to be enabled in your applications' nginx configs, you need to have installed nginx 1.11.5 or higher. See [issue 2435](https://github.com/dokku/dokku/issues/2435) for more details.
 
 ## Running behind a load balancer
 
 Your application has access to the HTTP headers `X-Forwarded-Proto`, `X-Forwarded-Port` and `X-Forwarded-For`. These headers indicate the protocol of the original request (HTTP or HTTPS), the port number, and the IP address of the client making the request, respectively. The default configuration is for Nginx to set these headers.
 
-If your server runs behind an HTTP/S load balancer, then Nginx will see all requests as coming from the load balancer. If your load balancer sets the `X-Forwarded-` headers, you can tell Nginx to pass these headers from load balancer to your application by using the following [nginx custom template](/docs/configuration/nginx.md#customizing-the-nginx-configuration)

 This could result in security issue, for example, if your application looks at the value of the `X-Forwarded-Proto` to determine if the request was made over HTTPS.
 
 ### SSL Port Exposure
 
-When your app is served from port `80` then the `/home/dokku/APP/nginx.conf` file will automatically be updated to instruct nginx to respond to ssl on port 443 as a new cert is added.  If your app uses a non-standard port (perhaps you have a dockerfile deploy exposing port `99999`) you may need to manually expose an ssl port via `dokku proxy:ports-add <APP> https:443:99999`.

+> Note: This walkthrough uses the hostname `dokku.me` in commands. When deploying to your own server, you should set the `DOKKU_DOMAIN` value in the `Vagrantfile` before you initialize the Vagrant VM.
+
 ## Deploy tutorial
 
-Once Dokku has been configured with at least one user, applications can be deployed via a `git push` command. To quickly see Dokku deployment in action, you can use the Heroku Ruby on Rails example app.
+Once you have configured Dokku with at least one user, you can deploy applications using `git push`. To quickly see Dokku deployment in action, try using [the Heroku Ruby on Rails "Getting Started" app](https://github.com/heroku/ruby-getting-started).
 
 ```shell
 # from your local machine
 # SSH access to github must be enabled on this host
-git clone git@github.com:heroku/ruby-rails-sample.git
+git clone https://github.com/heroku/ruby-getting-started
 ```
 
 ### Create the app
 
-Create the application on the Dokku host. You will need to ssh onto the host to run this command.
+SSH into the Dokku host and create the application as follows:
 
 ```shell
-# on your Dokku host
-dokku apps:create ruby-rails-sample
+# on the Dokku host
+dokku apps:create ruby-getting-started
 ```
 
 ### Create the backing services
 
-When you create a new app, Dokku by default *does not* provide any datastores such as MySQL or PostgreSQL. You will need to install plugins to handle that, but fortunately [Dokku has official plugins](/docs/community/plugins.md#official-plugins-beta) for common datastores. Our sample app requires a PostgreSQL service:
+Dokku by default **does not** provide datastores (e.g. MySQL, PostgreSQL) on a newly created app. You can add datastore support by installing plugins, and the Dokku project [provides official plugins](/docs/community/plugins.md#official-plugins-beta) for common datastores.
+
+The Getting Started app requires a PostgreSQL service, so install the plugin and create the related service as follows:
 
 ```shell
-# on your Dokku host
+# on the Dokku host
 # install the postgres plugin
 # plugin installation requires root, hence the user change
 sudo dokku plugin:install https://github.com/dokku/dokku-postgres.git
 
-# create a postgres service with the name rails-database
-dokku postgres:create rails-database
+# create a postgres service with the name railsdatabase
+dokku postgres:create railsdatabase
 ```
 
-> Each service may take a few moments to create.
+Each service may take a few moments to create.
 
 ### Linking backing services to applications
 
-Once the service creation is complete, set the `POSTGRES_URL` environment variable by linking the service.
+Once the services have been created, you then set the `DATABASE_URL` environment variable by linking the service, as follows:
 
 ```shell
-# on your Dokku host
+# on the Dokku host
 # each official datastore offers a `link` method to link a service to any application
-dokku postgres:link rails-database ruby-rails-sample
+dokku postgres:link railsdatabase ruby-getting-started
 ```
 
-> You can link a single service to multiple applications or use one service per application.
+Dokku supports linking a single service to multiple applications as well as linking only one service per application.
 
 ### Deploy the app
 
-Now you can deploy the `ruby-rails-sample` app to your Dokku server. All you have to do is add a remote to name the app. Applications are created on-the-fly on the Dokku server.
+> Warning: Your app should respect the `PORT` environment variable, otherwise it may not respond to web requests. You can find more information in the [port management documentation](/docs/networking/port-management.md).**
+
+Now you can deploy the `ruby-getting-started` app to your Dokku server. All you have to do is add a remote to name the app. Applications are created on-the-fly on the Dokku server.

-cd ruby-rails-sample
-git remote add dokku dokku@dokku.me:ruby-rails-sample
+cd ruby-getting-started
+git remote add dokku dokku@dokku.me:ruby-getting-started
 git push dokku master
 ```
 
+> Note: Some tools may not support the short-upstream syntax referenced above, and you may need to prefix
+> the upstream with the scheme `ssh://` like so: `ssh://dokku@dokku.me:ruby-getting-started`
+> Please see the [Git](https://git-scm.com/docs/git-clone#_git_urls_a_id_urls_a) documentation for more details.
+
+> Note: Your private key should be registered with `ssh-agent` in your local development environment. If you get a `permission denied` error when pushing, you can register your private key as follows: `ssh-add -k ~/<your private key>`.

-
-Dokku only supports deploying from its master branch, so if you'd like to deploy a different local branch use: ```git push dokku <local branch>:master```

-
-```shell
-# on your Dokku host
-
-# set it globally
-dokku config:set --global DOKKU_DEPLOY_BRANCH=some-branch

 # Buildpack Deployment
 
-Dokku normally defaults to using [heroku buildpacks](https://devcenter.heroku.com/articles/buildpacks) for deployment, though this may be overridden by committing a valid `Dockerfile` to the root of your repository and pushing the repository to your Dokku installation. To avoid this automatic `Dockerfile` deployment detection, you may do one of the following:

-- Add `BUILDPACK_URL` to a committed `.env` file in the root of your repository.

+
+> Warning: If using the `buildpacks` plugin, be sure to unset any `BUILDPACK_URL` and remove any such entries from a committed `.env` file. A specified `BUILDPACK_URL` will always override a `.buildpacks` file or the buildpacks plugin.
+
+Dokku normally defaults to using [Heroku buildpacks](https://devcenter.heroku.com/articles/buildpacks) for deployment, though this may be overridden by committing a valid `Dockerfile` to the root of your repository and pushing the repository to your Dokku installation. To avoid this automatic `Dockerfile` deployment detection, you may do one of the following:
+
+- Set a `BUILDPACK_URL` environment variable
+  - This can be done via `dokku config:set` or via a committed `.env` file in the root of the repository. See the [environment variable documentation](/docs/configuration/environment-variables.md) for more details.
 - Create a `.buildpacks` file in the root of your repository.
+  - This can be via a committed `.buildpacks` file or managed via the `buildpacks` plugin commands.
 
-## Specifying a custom buildpack
+This page will cover usage of the `buildpacks` plugin.
 
-In certain cases you may want to specify a custom buildpack. While Dokku uses herokuish to support all the [official heroku buildpacks](https://github.com/gliderlabs/herokuish#buildpacks), it is possible that the buildpack detection does not work well for your application. As well, you may wish to use a custom buildpack to handle specific application logic.
+## Usage
 
-To use a specific buildpack, you can run the following Dokku command:
+### Listing Buildpacks in Use
+
+The `buildpacks:list` command can be used to show buildpacks that have been set for an app. This will omit any auto-detected buildpacks.
 
 ```shell
-# replace REPOSITORY_URL with your buildpack's url
-dokku config:set node-js-app BUILDPACK_URL=REPOSITORY_URL
-
-# example: using a specific ruby buildpack version
-dokku config:set node-js-app BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-ruby.git#v142
+# running for an app with no buildpacks specified
+dokku buildpacks:list node-js-app
 ```
 
-Please check the documentation for your particular buildpack as you may need to include configuration files (such as a Procfile) in your project root.
+```
+-----> test buildpack urls
+```
 
-## Using multiple buildpacks
-
-You can only set a single buildpack using the `BUILDPACK_URL`, though there may be times when you wish to use multiple buildpacks. To do so, simply create a `.buildpacks` file in the base of your repository. This file should list all the buildpacks, one-per-line. For instance, if you wish to use both the `nodejs` and `ruby` buildpacks, your `.buildpacks` file should contain the following:
 
 ```shell
-https://github.com/heroku/heroku-buildpack-nodejs.git#v87
-https://github.com/heroku/heroku-buildpack-ruby.git#v142
+# running for an app with two buildpacks specified
+dokku buildpacks:list node-js-app
 ```
 
+```
+-----> test buildpack urls
+       https://github.com/heroku/heroku-buildpack-python.git
+       https://github.com/heroku/heroku-buildpack-nodejs.git
+```
+
+### Adding custom buildpacks
+
+> Please check the documentation for your particular buildpack as you may need to include configuration files (such as a Procfile) in your project root.
+
+To add a custom buildpack, use the `buildpacks:add` command:
+
+```shell
+dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-nodejs.git
+```
+
+When no buildpacks are currently specified, the specified buildpack will be the only one executed for detection and compilation.
+
+Multiple buildpacks may be specified by using the `buildpacks:add` command multiple times.
+
+```shell
+dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+dokku buildpacks:add node-js-app https://github.com/heroku/heroku-buildpack-nodejs.git
+```
+
+Buildpacks are executed in order, may be inserted at a specified index via the `--index` flag. This flag is specified starting at a 1-index value.
+
+```shell
+# will add the golang buildpack at the second position, bumping all proceeding ones by 1 position
+dokku buildpacks:add --index 2 node-js-app https://github.com/heroku/heroku-buildpack-golang.git
+```
+
+### Overwriting a buildpack position
+
+In some cases, it may be necessary to swap out a given buildpack. Rather than needing to re-specify each buildpack, the `buildpacks:set` command can be used to overwrite a buildpack at a given position.
+
+```shell
+dokku buildpacks:set node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+By default, this will overwrite the _first_ buildpack specified. To specify an index, the `--index` flag may be used. This flag is specified starting at a 1-index value, and defaults to `1`.
+
+```shell
+# the following are equivalent commands
+dokku buildpacks:set node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+dokku buildpacks:set --index 1 node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+If the index specified is larger than the number of buildpacks currently configured, the buildpack will be appended to the end of the list.
+
+```shell
+dokku buildpacks:set --index 99 node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+### Removing a buildpack
+
+> At least one of a buildpack or index must be specified
+
+A single buildpack can be removed by name via the `buildpacks:remove` command.
+
+```shell
+dokku buildpacks:remove node-js-app https://github.com/heroku/heroku-buildpack-ruby.git
+```
+
+Buildpacks can also be removed by index via the `--index` flag. This flag is specified starting at a 1-index value.
+
+```shell
+dokku buildpacks:remove node-js-app --index 1
+```
+
+### Clearing all buildpacks
+
+> This does not affect automatically detected buildpacks, nor does it impact any specified `BUILDPACK_URL` environment variable.
+
+The `buildpacks:clear` command can be used to clear all configured buildpacks for a specified app.
+
+```shell
+dokku buildpacks:clear node-js-app
+```
+
+### Displaying buildpack reports for an app
+
+You can get a report about the app's buildpacks status using the `buildpacks:report` command:
+
+```shell
+dokku buildpacks:report
+```
+
+```

+
+```shell
+dokku buildpacks:report node-js-app --buildpacks-list
+```

+### Switching from Dockerfile deployments
+
+If an application was previously deployed via Dockerfile, the following commands should be run before a buildpack deploy will succeed:
+
+```shell
+dokku config:unset --no-restart node-js-app DOKKU_DOCKERFILE_CMD DOKKU_DOCKERFILE_ENTRYPOINT DOKKU_PROXY_PORT_MAP
+```
+
+### Using a specific buildpack version
+
 > Always remember to pin your buildpack versions when using the multi-buildpacks method, or you may find deploys changing your deployed environment.
 
-You may also choose to set just a single buildpack in this file, though that is up to you.
-
-Please check the documentation for your particular buildpack(s) as you may need to include configuration files (such as a Procfile) in your project root.
-
-## Using a specific buildpack version
-
-As Dokku pins all buildpacks via herokuish releases, there may be occasions where a local buildpack version is out of date. If you wish to use a more recent version of the buildpack, you may use any of the above methods to specify a buildpack **without** the git sha attached like so:
+By default, Dokku uses the [gliderlabs/herokuish](https://github.com/gliderlabs/herokuish/) project, which pins all of it's vendored buildpacks. There may be occasions where the pinned version results in a broken deploy, or does not have a particular feature that is required to build your project. To use a more recent version of a given buildpack, the buildpack may be specified *without* a Git commit SHA like so:
 
 ```shell
 # using the latest nodejs buildpack
-dokku config:set node-js-app BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs
+dokku buildpacks:set node-js-app https://github.com/heroku/heroku-buildpack-nodejs
 ```
 
-You may also wish to use a **specific** version of a buildpack, which is also simple
+This will use the latest commit on the `master` branch of the specified buildpack. To pin to a newer version of a buildpack, a sha may also be specified by using the form `REPOSITORY_URL#COMMIT_SHA`, where `COMMIT_SHA` is any tree-ish git object - usually a git tag.
 
 ```shell
 # using v87 of the nodejs buildpack
-dokku config:set node-js-app BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs#v87
+dokku buildpacks:set node-js-app https://github.com/heroku/heroku-buildpack-nodejs#v87
 ```

+If an application was previously deployed via buildpacks, the following commands should be run before a Dockerfile deploy will succeed:

+```shell
+dokku config:unset --no-restart node-js-app DOKKU_PROXY_PORT_MAP

-> Note: Nginx does not support proxying UDP. UDP ports can be exposed by disabling the nginx proxy with `dokku proxy:disable myapp`
+## Build-time configuration variables
 
-If you do not explicitly `EXPOSE` a port in your `Dockerfile`, Dokku will configure the nginx proxy to listen on port 80 (and 443 for TLS) and forward traffic to your app listening on port 5000 inside the container. Just like buildpack apps, you can also use the `$PORT` environment variable in your app to maintain portability.
-
-When ports are exposed through the default nginx proxy, they are proxied externally as HTTP ports. At this time, in no case do we proxy plain TCP or UDP ports. If you would like to investigate alternative proxy methods, please refer to our [proxy management documentation](/docs/advanced-usage/proxy-management.md).

As an alternative, the `git:initialize` command can be used to trigger this creation:
+
+```shell
+# on the Dokku host
+
+# overrides any existing pre-receive hook
+dokku git:initialize node-js-app
+```
+
+In order for the above command to succeed, the application *must* already exist. 
+
+> Warning: If the `pre-receive` hook was customized in any way, this will overwrite that hook with the current defaults for Dokku.
+
+### Changing the deploy branch
+
+By default, Dokku will deploy code pushed to the `master` branch. In order to quickly deploy a different local branch, the following Git command can be used:
+
+```shell
+# on the local machine
+
+# where `SOME_BRANCH_NAME` is the name of the branch
+git push dokku SOME_BRANCH_NAME:master
+```
+
+In `0.12.0`, the correct way to change the deploy branch is to use the `git:set` Dokku command.
+
+```shell
+# on the Dokku host
+
+# override for all applications
+dokku git:set --global deploy-branch SOME_BRANCH_NAME
+
+# override for a specific app
+# where `SOME_BRANCH_NAME` is the name of the branch
+dokku git:set node-js-app deploy-branch SOME_BRANCH_NAME
+```
+
+Pushing multiple branches can also be supported by creating a [receive-branch](/docs/development/plugin-triggers.md#receive-branch) plugin trigger in a custom plugin.
+
+### Configuring the `GIT_REV` environment variable
+
+> New as of 0.12.0
+
+Application deployments will include a special `GIT_REV` environment variable containing the current deployment sha being deployed. For rebuilds, this SHA will remain the same.
+
+To configure the name of the `GIT_REV` environment variable, run the `git:set` command as follows:
+
+```shell
+# on the Dokku host
+
+# override for a specific app
+dokku git:set node-js-app rev-env-var DOKKU_GIT_REV
+```
+
+This behavior can be disabled entirely on a per-app basis by setting the `rev-env-var` value to an empty string:
+
+```shell
+# on the Dokku host
+
+# override for a specific app
+dokku git:set node-js-app rev-env-var ""
+```
+
+### Keeping the `.git` directory
+
+By default, Dokku will remove the contents of the `.git` before triggering a build for a given app. This is generally a safe default as shipping the entire source code history of your app in the deployed image artifact is unnecessary as it increases bloat and potentially can leak information if there are any security issues with your app code.
+
+To enable the `.git` directory, run the `git:set` command as follows:
+
+```shell
+# on the Dokku host
+
+# keep the .git directory during builds
+dokku git:set node-js-app keep-git-dir true
+```
+
+The default behavior is to delete this directory and it's contents. To revert to the default behavior, the `keep-git-dir` value can be set to either an empty string or `false`.
+
+```shell
+# on the Dokku host
+
+# delete the .git directory during builds (default)
+dokku git:set node-js-app keep-git-dir false
+
+# delete the .git directory during builds (default)
+dokku git:set node-js-app keep-git-dir ""
+```

+A common administrative task to perform is calling `docker inspect` on the containers that are running for an application.

 ```shell
-dokku ps node-js-app

 There are certain settings that can be configured via environment variables:
 
 - `DOKKU_DEFAULT_CHECKS_WAIT`: (default: `10`) If no user-defined checks are specified - or if the process being checked is not a `web` process - this is the period of time Dokku will wait before checking that a container is still running.
-- `DOKKU_DOCKER_STOP_TIMEOUT`: (default: `10`) Configurable grace period given to the `docker stop` command. If a container has not stopped by this time, a `kill -9` signal or equivalent is sent in order to force-terminate the container. Both the `ps:stop` and `apps:destroy` commands _also_ respect this value. If not specified, the docker defaults for the [docker stop command](https://docs.docker.com/engine/reference/commandline/stop/) will be used.
-- `DOKKU_WAIT_TO_RETIRE`: (default: `60`) After a successful deploy, the grace period given to old containers before they are stopped/terminated. This is useful for ensuring completion of long-running http connections.

+If your application needs a longer period to boot up - perhaps to load data into memory, or because of slow boot time - you may also use Dokku's `checks` functionality to more precisely check whether an application can serve traffic or not.
 
 Checks are run against the detected `web` process from your application's `Procfile`. For non-web processes, Dokku will fallback to the aforementioned process uptime check.
 
 To specify checks, add a `CHECKS` file to the root of your project directory. The `CHECKS` file should be plain text and may contain:

+# Plugin Building Tips
+
+## Always create a `plugin.toml`
+
+The `plugin.toml` file is used to describe the plugin in help output, and helps users understand the purpose of the plugin. This _must_ have a description and a version. The version _should_ be bumped at every plugin release.
+
+```toml
+[plugin]
+description = "dokku example plugin"
+version = "0.1.0"
+[plugin.config]
+```
+
+## Files should be executable
+
+Commands, subcommands, triggers and source shell scripts should all be executable. On a Unix-like machine, the following command can be used to make them executable:
+
+```shell
+chmod +x path/to/file
+```
+
+Non-executable commands, subcommands, and triggers will be ignored.
+
+## Use the `pipefail` bash option
+
+Consider whether to include the `set -eo pipefail` option. Look at the following example:
+
+```shell
+IMAGE=$(docker images | grep "user/repo" | awk '{print $3}')
+if [[ -z $IMAGE ]]; then
+  dokku_log_fail "user/repo image not found... Did you run 'dokku plugin:install'?"
+fi
+```
+
+If `user/repo` doesn't exist, Dokku exits just before the `awk` command and the `dokku_log_fail` message will never go to `STDOUT`. printed with echo. The `set -e` option should be used in this case.
+
+Here is the `help` entry for `set`:
+
+```
+help set
+Options:
+  -e  Exit immediately if a command exits with a non-zero status.
+  -o option-name
+      pipefail     the return value of a pipeline is the status of
+                   the last command to exit with a non-zero status,
+                   or zero if no command exited with a non-zero status
+```
+
+## Support trace mode
+
+Trace mode is useful for getting debugging output from plugins when the `--trace` flag is specified or `dokku trace:on` is triggered. This should be done at the top of each shell script:
 
 ```shell
 #!/usr/bin/env bash
-set -eo pipefail; [[ $DOKKU_TRACE ]] && set -x
+set -eo pipefail
+[[ $DOKKU_TRACE ]] && set -x
+```
+
+In the above example, the third line enables bash's debug mode, which prints command traces before executing command.
+
+## Verify the existence of dependencies
+
+If a plugin depends on a specific command-line tool, check whether that tool exists before utilizing it. Either `command -v` or `which` may be used to do so:
+
+```shell
+# `command -v` example
+if ! command -v "nginx" &>/dev/null; then
+  log-fail "Missing nginx, install it"
+fi
+
+# `which` example
+if ! which nginx >/dev/null 2>&1; then
+  log-fail "Missing nginx, install it"
+fi
+```
+
+In cases where a dependency should be installed before the plugin can be used at all, use the `dependencies` plugin trigger to install the dependency.
+
+## Implement a help command
+
+For plugins which expose commands, implement a `help` command. This may be empty, but should contain a listing of all available commands.
+
+Commas - `,` - are used in the help output for columnizing output. Verify that the plugin conforms to the spec by running `dokku help --all` and manually verifying the output.
+
+See the sample plugin below for an example.
+
+## Namespace commands
+
+All commands *should* be namespaced. In cases where a core plugin is overriden, the plugin _may_ utilize the a namespace in use by the core, but generally this should be avoided to reduce confusion as to where the command is implemented.
+
+## Implement a proper catch-all command
+
+As of 0.3.3, a catch-all should be implemented that exits with a `DOKKU_NOT_IMPLEMENTED_EXIT` code. This allows Dokku to output a `command not found` message.
+
+See the sample plugin below for an example.
+
+## Set app config without restarting
+
+In the case that a plugin needs to set app configuration settings and a restart should be avoided (default Heroku-style behavior) these "internal" commands provide this functionality:
+
+```shell
+config_set --no-restart node-js-app KEY1=VALUE1 [KEY2=VALUE2 ...]
+config_unset --no-restart node-js-app KEY1 [KEY2 ...]
+```
+
+## Expose functionality in a `functions` file
+
+To allow other plugins access to (some of) a plugin's functionality, functions can expose by including a `functions` file in the plugin for others to source. All functions in that file should be considered publicly accessible by other plugins.
+
+Any functions that must be kept private should reside in the plugin's `trigger/` or `commands/` directories. Other files may also be used to hide private functions; the official convention for hiding private functions is to place them an `internal-functions` file.
+
+## Use helper functions to fetch app images
+
+> New as of 0.4.0
+
+Dokku allows image tagging and deployment of tagged images. This means hard-coding the `$IMAGE` as `dokku/$APP` is no longer sufficient.
+
+Plugins should use `get_running_image_tag()` and `get_app_image_name()` as sourced from `common/functions`. See the [plugin triggers](/docs/development/plugin-triggers.md) doc for examples.
+
+> **Note:** This is only for plugins that are not `pre/post-build-*` plugins
+
+## Use `$DOCKER_BIN` instead of `docker` directly
+
+> New as of 0.17.5
+
+Certain systems may require a wrapper function around the `docker` binary for proper execution. Utilizing the `$DOCKER_BIN` environment variable when calling docker for those functions is preferred.
+
+```shell
+# good
+"$DOCKER_BIN" container run -d $IMAGE /bin/bash -e -c "$COMMAND"
+
+# bad
+docker run -d $IMAGE /bin/bash -e -c "$COMMAND"
+```
+
+## Include labels for all temporary containers and images
+
+> New as of 0.5.0
+
+As of 0.5.0, labels are used to help cleanup intermediate containers with `dokku cleanup`. Plugins that create containers and images should add the correct labels to the `build`, `commit`, and `run` docker commands.
+
+Note that where possible, a label `com.dokku.app-name=$APP` - where `$APP` is the name of the app - should also be included. This enables `dokku cleanup APP` to cleanup the specific containers for a given app.
+
+```shell
+# `docker build` example
+"$DOCKER_BIN" image build "--label=com.dokku.app-name=${APP}" $DOKKU_GLOBAL_BUILD_ARGS ...
+
+# `docker commit` example
+# Note that the arguments must be set as a local array
+# as arrays cannot be exported in shell
+local DOKKU_COMMIT_ARGS=("--change" "LABEL org.label-schema.schema-version=1.0" "--change" "LABEL org.label-schema.vendor=dokku" "--change" "LABEL $DOKKU_CONTAINER_LABEL=")
+"$DOCKER_BIN" container commit --change "LABEL com.dokku.app-name=$APP" "${DOKKU_COMMIT_ARGS[@]}" ...
+
+# `docker run` example
+"$DOCKER_BIN" container run "--label=com.dokku.app-name=${APP}" $DOKKU_GLOBAL_RUN_ARGS ...
+```
+
+## Copy files from the built image using `copy_from_image`
+
+Avoid copying files from running containers as these files may change over time. Instead copy files from the image built during the deploy process. This can be done via the `copy_from_image` helper function. This will correctly handle various corner cases in copying files from an image.
+
+```shell
 source "$PLUGIN_CORE_AVAILABLE_PATH/common/functions"
 
-hello_main_cmd() {
+local TMP_FILE=$(mktemp "/tmp/dokku-${DOKKU_PID}-${FUNCNAME[0]}.XXXXXX")
+trap "rm -rf '$TMP_FILE' >/dev/null" RETURN INT TERM
+
+local IMAGE_TAG="$(get_running_image_tag "$APP")"
+local IMAGE=$(get_deploying_app_image_name "$APP" "$IMAGE_TAG")
+copy_from_image "$IMAGE" "file-being-copied" "$TMP_FILE" 2>/dev/null
+```
+
+Files are copied from the `/app` directory - for images built via buildpacks - or `WORKDIR` - for images built via Dockerfile.
+
+## Avoid calling the `dokku` binary directly
+
+> New as of 0.6.0
+
+Plugins should **not** call the `dokku` binary directly from within plugins because clients using the `--app` argument are potentially broken when doing so.
+
+Plugins should instead source the `functions` file for a given plugin when attempting to call Dokku internal functions.
+

 ## Versioning
 
 Dokku follows semver standards. As we are not yet at a stable release, breaking changes will require *only* a minor release, while all other changes only require a patch release. Once we hit stable, breaking changes will require a major release.
 
-Tags should be created via the following method:
-
-```shell
-git tag v0.9.9
-```
-
 At the moment, tags need not be signed, though that may change in the future.
 
-## Debian and RPM packages
-
-The `build` target in the Dokku `Vagrantfile` creates debian and rpm packages for Dokku at a point in time. The version will be based upon the latest local tag - you may create your own, internal tags/releases if that is so desired.
-
-Debian package information is held in the `debian` directory of the Dokku project.
-
-For the public project, releases should be pushed to packagecloud.io *after* a tag is created but *before* said tag is pushed to github. The following may be the release workflow:
-
-
-```shell
-git tag v0.9.9
-vagrant up build
-export PACKAGECLOUD_TOKEN=SOME_TOKEN
-package_cloud push dokku/dokku/ubuntu/trusty dokku_0.9.9_amd64.deb
-package_cloud push dokku/dokku/el/7 dokku-0.9.9-1.x86_64.rpm
-```
-
-If new versions of other packages were created, these should also be pushed at this time.

 ## ArchLinux Packages
 
 ArchLinux packages are not really build, because all that is needed for an Arch User Repo (AUR) package is the description of how to build the package. To make this process as easy as possible there is a vagrant box called `build-arch` that updates the version of this build description (a file called `PKGBUILD`), then runs some helper scripts to fill all additional information and does test if the package could be build. Then only those changes need to be pushed to the AUR repo and an updated version of the package is ready for usage for our ArchLinux users. For detailed information see the section below.

+For Debian, unattended installation is described [Debian installation guide](/docs/getting-started/install/debian.md).
 
 *You should also stop and disable the `dokku-installer` service to remove public access to adding SSH keys.*
 
-Set up a domain and a wildcard domain pointing to that host. Make sure `/home/dokku/VHOST` is set to this domain. By default it's set to whatever hostname the host has. This file is only created if the hostname can be resolved by dig (`dig +short $(hostname -f)`). Otherwise you have to create the file manually and set it to your preferred domain. If this file still is not present when you push your app, Dokku will publish the app with a port number (i.e. `http://example.com:49154` - note the missing subdomain).
+Set up a domain using your preferred vendor and a wildcard domain pointing to the host running Dokku. You can manage this global domain using the [domains plugin](/docs/configuration/domains.md).
 
-Follow the [user management documentation](/docs/deployment/user-management.md) in order to add users to Dokku, or to give other Unix accounts access to Dokku.

+# Docker Installation Notes
+
+Pull the dokku/dokku image:
+
+```shell
+docker pull dokku/dokku:0.20.0
+```
+
+Next, run the image.
+
+```shell
+docker run \
+  --env DOKKU_HOSTNAME=dokku.me \
+  --name dokku \
+  --publish 3022:22 \
+  --publish 8080:80 \
+  --publish 8443:443 \
+  --volume /var/lib/dokku:/mnt/dokku \
+  --volume /var/run/docker.sock:/var/run/docker.sock \
+  dokku/dokku:0.20.0
+```
+
+Dokku is run with the following options:
+
+- The global hostname is set to `dokku.me` on boot.
+- The container name is dokku.
+- Container SSH port 22 is exposed on the host as 3022.
+- Container HTTP port 80 is exposed on the host as 8080.
+- Container HTTPS port 443 is exposed on the host as 8443.
+- Data within the container is stored on the host within the `/var/lib/dokku` directory.
+- The docker socket is mounted into container
+
+Application repositories, plugin config, and plugin data is persisted to disk within the specified host directory for `/var/lib/dokku`.
+
+To install custom plugins, create a `plugin-list` file in the host's `/var/lib/dokku` directory. The plugins listed herein will be automatically installed by Dokku on container boot. This file should be the following format:
+
+```yaml
+plugin_name: repository_url
+```
+
+An example for installing the postgres and redis plugins follows:
+
+```yaml
+postgres: https://github.com/dokku/dokku-postgres.git
+redis: https://github.com/dokku/dokku-redis.git
+```
+
+To initialize ssh-keys within the container, use `docker exec` to enter the container and run the appropriate ssh-keys commands.
+
+```shell
+docker exec -it dokku bash
+```
+
+Please see the [user management documentation](/docs/deployment/user-management.md) for more information.
