+
+## Requirements
+
+A fresh VM running any of the following operating systems:
+
+- Ubuntu 16.04/18.04/20.04 x64 - Any currently supported release
+- Debian 9+ x64
+- CentOS 7 x64 *(experimental)*
+- Arch Linux x64 *(experimental)*
+
+An SSH keypair that can be used for application deployment. If this exists before installation, it will be automatically imported into dokku.
+Otherwise, you will need to import the keypair manually after installation using `dokku ssh-keys:add`.
+
+## 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/v0.22.2/bootstrap.sh
+sudo DOKKU_TAG=v0.22.2 bash bootstrap.sh
+```
+
+You can then proceed to the ip address or domain name associated with your server to complete the web-based installation.
+
+If you wish for a more unattended installation method, see [these](http://dokku.viewdocs.io/dokku/getting-started/install/debian/#unattended-installation) docs.
+
+### Upgrade
+
+[View the docs](http://dokku.viewdocs.io/dokku/getting-started/upgrading/) for upgrading from an older version of Dokku.

-# Advanced installation
-
-You can always install dokku straight from the latest - potentially unstable - master release via the following bash command:
-
-```shell
-wget -qO- https://raw.githubusercontent.com/progrium/dokku/master/bootstrap.sh | sudo DOKKU_BRANCH=master bash
-```
-
-## Development
-
-If you plan on developing dokku, the easiest way to install from your own repository is cloning the repository and calling the install script. Example:
-
-```shell
-git clone https://github.com/yourusername/dokku.git
-cd dokku
-sudo make install
-```
-
-The `Makefile` allows source URLs to be overridden to include customizations from your own repositories. The `DOCKER_URL`, `PLUGN_URL`, `SSHCOMMAND_URL` and `STACK_URL` environment variables may be set to override the defaults (see the `Makefile` for how these apply). Example:
-
-```shell
-sudo SSHCOMMAND_URL=https://raw.githubusercontent.com/yourusername/sshcommand/master/sshcommand make install
-```
-
-## Bootstrap a server from your own repository
-
-The bootstrap script allows the dokku repository URL to be overridden to bootstrap a host from your own clone of dokku using the `DOKKU_REPO` environment variable. Example:
-
-```shell
-wget https://raw.githubusercontent.com/progrium/dokku/master/bootstrap.sh
-chmod +x bootstrap.sh
-sudo DOKKU_REPO=https://github.com/yourusername/dokku.git DOKKU_BRANCH=master ./bootstrap.sh
-```
-
-## Custom herokuish build
-
-Dokku ships with a pre-built version of version of the [herokuish](https://github.com/gliderlabs/herokuish) component by default. If you want to build your own version you can specify that with an env variable.
-
-```shell
-git clone https://github.com/progrium/dokku.git
-cd dokku
-sudo BUILD_STACK=true STACK_URL=https://github.com/gliderlabs/herokuish.git make install
-```
-
-## Configuring
-
-Once dokku is installed, if you are not using the web-installer, you'll want to configure a the virtualhost setup as well as the push user. If you do not, your installation will be considered incomplete and you will not be able to deploy applications.
-
-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).
-
-You'll have to add a public key associated with a username by doing something like this from your local machine:
-
-    $ cat ~/.ssh/id_rsa.pub | ssh dokku.me "sudo sshcommand acl-add dokku $USER"
-
-If you are using the vagrant installation, you can use the following command to add your public key to dokku:
-
-    $ cat ~/.ssh/id_rsa.pub | make vagrant-acl-add
-
-That's it!
-
-## VMs with less than 1GB of memory
-
-Having less than 1GB of system memory available for dokku and its containers, for example Digital Ocean's small 512MB machines, might result in unexpected errors, such as **! [remote rejected] master -> master (pre-receive hook declined)** during installation of NPM dependencies (https://github.com/npm/npm/issues/3867).
-
-To work around this issue, it might suffice to augment the linux swap file size to a maximum of twice the physical memory size.
-
-To resize the swap file of a 512MB machine to 1GB, follow these steps while in SSH within your machine:
-
-```shell
-cd /var
-touch swap.img
-chmod 600 swap.img
-
-dd if=/dev/zero of=/var/swap.img bs=1024k count=1000
-mkswap /var/swap.img
-swapon /var/swap.img
-free
-
-echo "/var/swap.img    none    swap    sw    0    0" >> /etc/fstab
-```

+# Backup and Recovery
+
+> The backup plugin was deprecated in 0.4.x, below are backup recommendations for 0.5.x and later.
+
+The best plan for disaster recovery is to always keep multiple (remote) copies of your local repo, static assets and periodic database dumps. Backups should be regularly tested for data integrity and completeness.

+
+> Warning: This method has many caveats. Please read this entire document before assuming these backups work as expected, and test your backups on a regular basis.
+
+### Creating a backup
+
+To create a backup, run the following command at a time when not executing any Dokku commands or app deployments:
+
+```shell
+export BACKUP_TIME=$(date +%Y-%m-%d-%H-%M)
+sudo mkdir -p /var/lib/dokku/services
+sudo chown dokku:dokku /var/lib/dokku/services
+mkdir -p /tmp/dokku-backups/
+sudo tar -czvf "/tmp/dokku-backups/${BACKUP_TIME}.tar.gz" /home/dokku /var/lib/dokku/config /var/lib/dokku/data /var/lib/dokku/services /var/lib/dokku/plugins
+```
+
+This will create a point-in-time backup of your entire Dokku installation in the `/tmp/dokku-backups` directory. This backup may be moved offsite to another location via rsync, sftp, or some other protocol.
+
+It is recommended that backups are regularly cleaned from the originating server and tested as necessary.
+
+### Restoring a backup
+
+To extract the backup onto another server, copy the backup to the server and extract it using the following command.
+
+```shell
+sudo tar -xzvf path/to/dokku/backup.tar.gz -C /
+```
+
+At this point, all datastores should be individually started and checked for data integrity. Once this is complete, individual applications can be rebuilt. Please consult the [process management documentation](/docs/deployment/process-management.md#rebuilding-apps) for more information on how to rebuild applications.
+
+## Caveats
+
+### App config
+
+Application config is largely held in a small number of places:
+
+- `/var/lib/dokku/config`: Properties set and managed by plugins
+- `/var/lib/dokku/data`: Files generated or extracted by various plugins
+- `/home/dokku`: Certain parts of Dokku core store data in this location
+
+Compressing these directories when no Dokku commands are running is enough to ensure a complete backup of the system.
+
+### Code Repositories
+
+Because Dokku is git based, rebuilding a deployed app is as easy as pushing from git. You can push to a new server by updating the `dokku` remote in you local app's repo.
+
+```shell
+git remote rm dokku
+git remote add dokku dokku@[dokku.me:dokku.me]
+git push dokku [master]
+```
+
+### Docker Image and Tar-based Apps
+
+These applications may fail to rebuild via the normal `ps:rebuild` method. Redeploy these apps by running the original commands used to deploy them
+
+### Datastores
+
+> Please note that point-in-time backups of the `/var/lib/dokku/services` directory may contain partially written data due to how various datastores work. Consult the official datastore documentation for the best documentation surrounding proper backup and restore procedures.
+
+Some plugins, like the official [dokku-postgres](https://github.com/dokku/dokku-postgres) plugin, have built-in commands that allow non-volatile data be exported and imported.
+
+For [dokku-postgres](https://github.com/dokku/dokku-postgres), use:
+
+```shell
+dokku postgres:export [db_name] > [db_name].dump
+dokku postgres:import [db_name] < [db_name].dump
+```
+
+Additionally, data for official datastores is located in the `/var/lib/dokku/services` directory. If the directory is restored and the plugin is available, a `dokku $SERVICE:start` may be enough to restart the service with the underlying data, so long as the datastore version does not change and the underlying data is not corrupt. If this is the case, it may be necessary to re-import all the data onto a fresh version of the datastore service.
+
+### Plugins
+
+The plugin directory is contained at the `/var/lib/dokku/plugins` directory. Core plugins will automatically be included in new installs, but custom plugins may not. The aforementioned `tar` creation command will back all plugins up, and the `tar` extract command will restore the plugins.
+
+Note that restoring a plugin will not trigger any `install` or `dependencies` triggers. You will need to run these manually. See the [plugin management documentation](/docs/advanced-usage/plugin-management.md#installing-a-plugin) for more information on how to trigger these two hooks.
+
+
+### Volumes and Static Assets
+
+Dokku doesn't enforce a [300mb](https://devcenter.heroku.com/articles/slug-compiler#slug-size) limit on apps, but it's best practice to keep binary assets outside of git. Since containers are considered volatile in Dokku, external stores like s3 or storage mounts should be used for non-volatile items like user uploads. The Dokku storage core plugin can be used to mount local directories / volumes inside the docker container.
+
+System administrators are highly encouraged to store persistent data in app-specific subdirectories of the path `/var/lib/dokku/data/storage`. This will help ensure restores of the aforementioned primary Dokku directories will restore service to all apps.
+
+See the [persistent storage documentation](/docs/advanced-usage/persistent-storage.md) for more information on how to attach persistent storage to your application.
+
+## Recovering app code
+
+In case of an emergency when your git repo and backups are completely lost, you can recover the last pushed copy from your remote Dokku server (assuming you still have the ssh key).
+
+```shell
+mkdir [app-name] ; cd !$
+git init && git remote add dokku dokku@[dokku.me:app-name]
+git pull dokku/master && git checkout dokku/master
+```

+# Deployment Tasks
+
+> New as of 0.5.0
+
+Sometimes you need to run a command on 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`)
+
+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.
+
+Each "phase" has different expectations and limitations:
+
+- `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
+
+Additionally, if using a Dockerfile with an `ENTRYPOINT`, the deployment task is passed to that entrypoint as is.
+
+Please keep the above in mind when utilizing deployment tasks.
+
+> 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.
+
+```json
+{
+  "scripts": {
+    "dokku": {
+      "predeploy": "touch /app/predeploy.test",
+      "postdeploy": "curl https://some.external.api.service.com/deployment?state=success"
+    }
+  }
+}
+```
+
+## 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.

+
+## About Dokku phases
+
+Dokku deploys your application in multiple "phases" and the `docker-options` plugin allows you to pass arguments to their underlying docker container:
+
+- `build`: the container that executes the appropriate buildpack
+- `deploy`: the container that executes your running/deployed application
+- `run`: the container that executes any arbitrary command via `dokku run`
+
+Manipulation of docker options will not restart running containers. This enables multiple options to be set/unset before final application. As such, changing an app's docker options must be followed by a `dokku ps:rebuild` in order to take effect.
+
+More information on supported Docker options can be found here: https://docs.docker.com/engine/reference/commandline/run/.
+
+## Examples
+
+### Add Docker options
+
+Add some options for the deployed/running app and when executing [`dokku run`](/docs/deployment/one-off-processes.md):
+
+```shell
+# Mount a host volume in a Docker container: "-v /host/path:/container/path"
+dokku docker-options:add node-js-app deploy "-v /var/log/node-js-app:/app/logs"
+dokku docker-options:add node-js-app run "-v /var/log/node-js-app:/app/logs"
+```
+
+> Note: When [mounting a host directory](https://docs.docker.com/engine/reference/run/#volume-shared-filesystems) in a Dokku app you should first create that directory as user `dokku` and then mount the directory under `/app` in the container using `docker-options` as above. Otherwise the app will lack write permission in the directory.
+
+### Remove a Docker option
+
+```shell
+dokku docker-options:remove node-js-app run "-v /var/log/node-js-app:/app/logs"
+```
+
+### Clear all Docker options for an app
+
+Docker options can be removed for a specific app using the `docker-options:clear` command.
+
+```shell
+dokku docker-options:clear node-js-app
+```
+
+```
+-----> Clearing docker-options for node-js-app on all phases
+```
+
+One or more valid phases can also be specified. Phases are comma delimited, and specifying an invalid phase will result in an error.

+# Persistent Storage
+
+> New as of 0.5.0
+
+The preferred method to mount external containers to a Dokku managed container, is to use the Dokku storage plugin.
+
+
+```
+storage:list <app>                             # List bind mounts for app's container(s) (host:container)
+storage:mount <app> <host-dir:container-dir>   # Create a new bind mount
+storage:report [<app>] [<flag>]                # Displays a checks report for one or more apps
+storage:unmount <app> <host-dir:container-dir> # Remove an existing bind mount
+```
+
+> 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.
+
+The storage plugin supports the following mount points:
+
+- 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.
+
+## Usage
+
+This example demonstrates how to mount the recommended directory to `/storage` inside an application called `node-js-app`:
+
+```shell
+# we use a subdirectory inside of the host directory to scope it to just the app
+dokku storage:mount node-js-app /var/lib/dokku/data/storage/node-js-app:/storage
+```
+
+Dokku will then mount the shared contents of `/var/lib/dokku/data/storage` to `/storage` inside the container.
+
+Once you have mounted persistent storage, you will also need to restart the application. See the
+[process scaling documentation](/docs/deployment/process-management.md) for more information.
+
+```shell
+dokku ps:restart app-name
+```
+
+A more complete workflow may require making a custom directory for your application and mounting it within your `/app/storage` directory instead. The mount point is *not* relative to your application's working directory, and is instead relative to the root of the container.
+
+```shell
+# creating storage for the app 'node-js-app'
+mkdir -p  /var/lib/dokku/data/storage/node-js-app
+
+# ensure the proper user has access to this directory
+chown -R dokku:dokku /var/lib/dokku/data/storage/node-js-app
+
+# as of 0.7.x, you should chown using the `32767` user and group id for buildpack deploys
+# For dockerfile deploys, substitute the user and group id in use within the image
+chown -R 32767:32767 /var/lib/dokku/data/storage/node-js-app
+
+# mount the directory into your container's /app/storage directory, relative to root
+dokku storage:mount app-name /var/lib/dokku/data/storage/node-js-app:/app/storage
+```
+
+You can mount one or more directories as desired by following the above pattern.
+
+### Displaying storage reports for an app
+
+> New as of 0.8.1
+
+You can get a report about the app's storage status using the `storage:report` command:
+
+```shell
+dokku storage:report
+```
+
+```
+=====> node-js-app storage information
+       Storage build mounts:
+       Storage deploy mounts: -v /var/lib/dokku/data/storage/node-js-app:/app/storage

+```shell
+dokku storage:report node-js-app
+```
+
+```
+=====> node-js-app storage information
+       Storage build mounts:
+       Storage deploy mounts: -v /var/lib/dokku/data/storage/node-js-app:/app/storage
+       Storage run mounts:  -v /var/lib/dokku/data/storage/node-js-app:/app/storage
+```
+
+You can pass flags which will output only the value of the specific information you want. For example:
+
+```shell
+dokku storage:report node-js-app --storage-deploy-mounts
+```
+
+## Use Cases
+
+### Persistent storage
+
+Dokku is powered by Docker containers, which recommends in their [best practices](https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/#containers-should-be-ephemeral) that containers be treated as ephemeral. In order to manage persistent storage for web applications, like user uploads or large binary assets like images, a directory outside the container should be mounted.
+
+### Shared storage between containers
+
+When scaling your app, you may require a common location to access shared assets between containers, a storage mount can be used in this situation.
+
+### Shared storage across environments
+
+Your app may be used in a cluster that requires containers or resources not running on the same host access your data. Mounting a shared file service (like S3FS or EFS) inside your container will give you great flexibility.
+
+### Backing up
+
+Your app may have services that are running in memory and need to be backed up locally (like a key store). Mount a non ephemeral storage mount will allow backups that are not lost when the app is shut down.
+
+### Build phase
+
+By default, Dokku will only bind storage mounts during the deploy and run phases. Under certain conditions, one might want to bind a storage mount during the build phase. This can be accomplished by using the `docker-options` plugin directly.
+
+```shell
+dokku docker-options:add node-js-app build "-v /tmp/python-test:/opt/test"
+```
+
+You cannot use mounted volumes during the build phase of a Dockerfile deploy. This is because Docker does not support volumes when executing `docker build`.
+
+> Note: **This can cause data loss** if you bind a mount under `/app` in buildpack apps as herokuish will attempt to remove the original app path during the build phase.
+
+## Application User and Persistent Storage file ownership (buildpack apps only)
+
+> New as of 0.7.1
+
+By default, Dokku will execute your buildpack application processes as the `herokuishuser` user. You may override this by setting the `DOKKU_APP_USER` config variable.
+
+> NOTE: this user must exist in your herokuish image.
+
+Additionally, the default `docker-local` scheduler that comes with Dokku will ensure your storage mounts are owned by either `herokuishuser` or the overridden value you have set in `DOKKU_APP_USER`. See the [docker-local scheduler documentation](/docs/advanced-usage/schedulers/docker-local.md#disabling-chown-of-persistent-storage) docs for more information.

+
+> Warning: All plugin commands other than `plugin:list` and `plugin:help` require sudo access and must be run directly from the Dokku server.
+
+### Checking if a plugin is installed
+
+You can check if a plugin has been installed via the `plugin:installed` command:
+
+```shell
+dokku plugin:installed postgres
+```
+
+### Installing a plugin
+
+Installing a plugin is easy as well using the `plugin:install` command. This command will also trigger the `install` pluginhook on all existing plugins.
+
+The most common usage is to install a plugin from a url. This url may be any of the following:
+
+- `git`: For git+ssh based plugin repository clones.
+- `ssh`: For git+ssh based plugin repository clones.
+- `file`: For copying plugins from a path on disk.
+- `https`: For http based plugin repository clones.
+
+Additionally, any urls with the extensions `.tar.gz` or `.tgz` are treated as Gzipped Tarballs for installation purposes and will be downloaded and extracted into place.
+
+```shell
+dokku plugin:install https://github.com/dokku/dokku-postgres.git
+```
+
+```
+-----> Cloning plugin repo https://github.com/dokku/dokku-postgres.git to /var/lib/dokku/plugins/available/postgres
+Cloning into 'postgres'...
+remote: Counting objects: 646, done.
+remote: Total 646 (delta 0), reused 0 (delta 0), pack-reused 646
+Receiving objects: 100% (646/646), 134.24 KiB | 0 bytes/s, done.
+Resolving deltas: 100% (406/406), done.
+Checking connectivity... done.
+-----> Plugin postgres enabled
+```
+
+For git-based plugin installation, a commit SHA-like object may be specified (tag/branch/commit sha) via the `--committish` argument and Dokku will attempt to install the specified commit object.
+
+```shell
+# where 2.0.0 is a potential git tag
+dokku plugin:install https://github.com/dokku/dokku-postgres.git --committish 2.0.0
+```
+
+Plugin names are interpolated based on the repository name minus the `dokku-` prefix. If the plugin being installed has a name other than what matches the repository name - or another name is desired - the `--name` flag can be used to override this interpolation.
+
+```shell
+dokku plugin:install https://github.com/dokku/smoke-test-plugin.git --name smoke-test-plugin
+```
+
+The `--core` flag may also be indicated as the sole argument, though it is only for installation of core plugins, and thus not useful for end-user installations.
+
+```shell
+dokku plugin:install --core
+```
+
+Finally, all flags may be omitted to trigger the `install` procedures for both core and third-party plugins:
+
+```shell
+dokku plugin:install
+```
+
+### Installing plugin dependencies
+
+In some cases, plugins will have system-level dependencies. These are not automatically installed via `plugin:install`, and must be separately via the `plugin:install-dependencies` command. This will run through all the `dependencies` trigger for all plugins.
+
+```shell
+dokku plugin:install-dependencies
+```
+
+This command may also target _just_ core plugins via the `--core` flag. This is usually only useful for source-based installs of Dokku.
+
+```shell
+dokku plugin:install-dependencies --core
+```
+
+### Updating a plugin
+
+An installed, third-party plugin can be updated can updated via the `plugin:update` command. This should be done after any upgrades of Dokku as there may be changes in the internal api that require an update of how the plugin interfaces with Dokku.
+
+Please note that this command is only valid for plugin installs that were backed by a git-repository.
+
+```shell
+dokku plugin:update postgres
+```
+
+```
+Plugin (postgres) updated
+```
+
+An optional commit SHA-like object may be specified.
+
+```shell
+dokku plugin:update postgres 2.0.0
+```
+
+### Uninstalling a plugin
+
+Third party plugins can be uninstalled using the `plugin:uninstall` command:
+
+```shell
+dokku plugin:uninstall postgres
+```
+
+```
+-----> Plugin postgres uninstalled
+```
+
+### Disabling a plugin
+
+Disabling a plugin can also be useful for debugging whether a third-party plugin is causing issues in a Dokku installation. Another common use case is for disabling core functionality for replacement with a third-party plugin.
+
+```shell
+dokku plugin:disable postgres
+```
+
+```
+-----> Plugin postgres disabled
+```
+
+### Enabling a plugin
+
+Disabled plugins can be re-enabled via the `plugin:enable` command.
+
+```shell
+dokku plugin:enable postgres
+```
+
+```
+-----> Plugin postgres enabled
+```
+
+### Triggering a plugin trigger
+
+The `plugin:trigger` can be used to call any internal plugin trigger. This may have unintended consequences, and thus should only be called for development or debugging purposes.
+
+```shell
+dokku plugin:trigger some-internal-trigger args-go-here
+```

+```
+
+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.
+
+> Warning: The meaning of a values and it's units are specific to the scheduler in use for a given app. If a value is incorrect for a scheduler, this may result in containers failing to start correctly. 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`
+- `--nvidia-gpu`
+
+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]

+       network-ingress:
+       network-egress:
+       nvidia-gpu:
+```
+
+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
+```

+       network-ingress:
+       network-egress:
+       nvidia-gpu:
+```
+
+#### 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

+```
+-----> 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

+
+- [Kubernetes](https://github.com/dokku/dokku-scheduler-kubernetes)
+- [Nomad](https://github.com/dokku/dokku-scheduler-nomad)
+
+These scheduler implementations may not be complete, though provide enough functionality for a user to get an app deployed via the underlying scheduler.

+
+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

+### 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
+```
+

+## PCI Compliance
+
+By default, Dokku will ship a PCI Compliant nginx configuration. For developers whose users are on older browsers or mobile devices, you may need to ship a custom `nginx.conf.sigil` to enable ciphers for older browsers.
+
+See the [nginx customization](/docs/configuration/nginx/#customizing-the-nginx-configuration) docs for more details.
+
+## Nginx Error Pages
+
+We now ship with nicer error pages by default. You are free to customize your Dokku installation via a custom `nginx.conf.sigil` to change what error pages are displayed in different circumstances.
+
+See the [nginx customization](/docs/configuration/nginx/#customizing-the-nginx-configuration) docs for more details.

+# 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.
+
+### Function renames
+
+- `tar#tar_in_cmd` was renamed to `tar#cmd-tar-in`. Users should avoid using `cmd-*` commands directly, and instead file an issue to have them exposed via a plugin trigger.
+- `tar#tar_from_cmd` was renamed to `tar#cmd-tar-from`. Users should avoid using `cmd-*` commands directly, and instead file an issue to have them exposed 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.
+
+## App report output
+
+When an app is not deployed, the `apps:report` command no longer shows the message `not deployed`. Please use the `--deployed` flag on `ps:report` instead to see if the app has been deployed.
+
+## 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`.

+# 0.21.0 Migration Guide
+
+## Changes
+
+The `tls` name is no longer a reserved app name, and can be used by applications. This was previously a reserved app name due to it's use as a place for global SSL certificate files; Dokku has not supported global SSL certificates for many releases, and thus there is no need to reserve the name.
+
+## Deprecations
+
+- `git#git_deploy_branch()` is deprecated in favor of `plugn trigger git-deploy-branch`.
+- The `config` command is deprecated in favor of `config:show`.
+  - Usage of this command in conjunction with either the `--export` or `--shell` flag is deprecated in favor of `config:export --format` with the correct format value (`exports` or `shell`, respectively).
+- The `nginx:build-config` command is deprecated in favor of `proxy:build-config`.
+
+## Removals
+
+The `apps:destroy` command no longer takes a second argument `force`. Instead, this can be passed as the `--force` flag, either globally or as a flag to the command itself.
+
+The `proxy:enable` and `proxy:disable` no longer restart apps when setting the `DOKKU_DISABLE_PROXY` environment variable. A future release will disable usage of `DOKKU_DISABLE_PROXY` altogether.

+- Underscores are no longer valid characters in app names. Please rename applications before upgrading.
+- Process type names specified in Procfile may no longer use characters not valid in DNS Label Names ([RFC 1123](https://tools.ietf.org/html/rfc1123)).
+- The minimum Docker version is now 17.05.0.
+- The `common.GetDeployingAppImageName()` function now returns an `error` as the second return argument instead of calling `common.LogFail()` internally.

+  - No need to escape literal `$` characters (or other "bash-isms")
+  - Template variables are represented as {{ .VARIABLE_NAME }}
+  - A detailed list of template variables can be found [here](/docs/configuration/nginx.md#available-template-variables)
+- A custom nginx-vhosts template must be named `nginx.conf.sigil`
+  - The default path for this custom template is the root of your repo (i.e. `/app` in the container or `WORKDIR` if defined in a dockerfile app)
+  - Dokku no longer looks for this file in `/home/dokku/node-js-app` on the Dokku server
+  - Check out an example template [here](/docs/configuration/nginx.md)
+- Support for server-wide SSL certs have been dropped in favor of using the `certs` plugin
+  - `dokku certs:add node-js-app < certs.tar`
+- All domains for an SSL-enabled app will be redirected to https by default
+  - This can be overridden with a custom template
+- Replaced "magic" `NO_VHOST` variable with `domains:enable/disable`
+- Simplified zero downtime control
+  - `checks:enable/disable`

+## Proxy port mapping
+
+- You can now configure host -> container proxy port mappings
+  - The UI is handled by the [proxy](/docs/advanced-usage/proxy-management.md) interface plugin by setting the `DOKKU_PROXY_PORT_MAP` config variable in the format of `scheme:host-port:container-port`. The default `nginx-vhosts` proxy plugin supports both the `http` and `https` schemes.
+- Default port mappings
+  - buildpack apps will be set to `http:80:5000` and will also include `https:443:5000` if SSL is enabled.
+  - dockerfile apps with explicitly exposed ports (i.e. using the `EXPOSE` directive) will be configured with a listener on each exposed port that proxies to the same port of the deployed application container.
+    - You may override this behavior with the [`proxy:ports-*` commands](/docs/advanced-usage/proxy-management.md) or by directly setting `DOKKU_PROXY_PORT_MAP` with the `config:set` command
+    - dockerfile apps without explicitly exposed ports will behave the same as a buildpack app
+  - NOTE: These defaults **are not** automatically changed on subsequent pushes and must be manipulated with the aforementioned commands
+
+## Calling the `dokku` binary
+
+- Plugins should *not* call the `dokku` binary directly. Clients using the `--app` argument are potentially broken, amongst others, when doing so. Instead, please source the `functions` file for a given plugin when attempting to call Dokku internal functions. As a result, the following Dokku commands are no longer publicly exposed:
+ - `dokku build`
+ - `dokku receive`
+ - `dokku release`
+ - `dokku tar:build`
+ - `dokku tar:build-locked`
+ - `dokku git:build`

-# Deploying to Dokku
-
-## 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.
-
-```shell
-git clone git@github.com:heroku/ruby-rails-sample.git
-```
-
-### Create the app
-
-Create the application on the Dokku host. You will need to ssh onto the host to run this command.
-
-```shell
-dokku apps:create ruby-rails-sample
-```
-
-### 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](/dokku/plugins/#official-plugins-beta) for common datastores. Our sample app requires a PostgreSQL service:
-
-```shell
-# 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
-```
-
-> Each services 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.
-
-```shell
-# each official datastore offers a `link` method to link a service to any application
-dokku postgres:link rails-database ruby-rails-sample
-```
-
-> You can link a single service to multiple applications or use 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.
-
-```shell
-git remote add dokku dokku@dokku.me:ruby-rails-sample
-git push dokku master
-```
-
-You should see output similar to the following:
-
-```
-Counting objects: 231, done.
-Delta compression using up to 8 threads.
-Compressing objects: 100% (162/162), done.

-
-When the deploy finishes, the application's URL will be shown.
-
-```shell
-=====> Application deployed:
-       http://ruby-rails-sample.dokku.me
-```
-
-Dokku supports deploying applications via [Heroku buildpacks](https://devcenter.heroku.com/articles/buildpacks) with [Herokuish](https://github.com/gliderlabs/herokuish#buildpacks) or using a project's [dockerfile](https://docs.docker.com/reference/builder/).
-
-### Removing a deployed app
-
-You can also remove an application from your Dokku installation. This will unlink all linked services and destroy any config related to the application. Note that linked services will retain their data for later use (or removal).
-
-```shell
-# replace APP with the name of your application
-dokku apps:destroy APP
-```
-
-This will prompt you to verify the application's name before destroying it. You may also use the `--force` flag to circumvent this verification process:
-
-```shell
-# replace APP with the name of your application
-dokku --force apps:destroy APP
-```
-
-### Adding deploy users
-
-While it is possible to use password-based authorization to push to Dokku, it is preferable to use key-based authentication for security. You can add your public key to the dokku user's `authorized_keys` file with the following command:
-
-```shell
-# replace dokku.me with your domain name or the host's IP
-# replace root with your server's root user
-cat ~/.ssh/id_rsa.pub | ssh root@dokku.com "sudo sshcommand acl-add dokku [description]"
-```
-
-### Deploying non-master branch
-
-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```
-
-You can also support pushing multiple branches using the [receive-branch](/dokku/development/plugin-triggers/#receive-branch) plugin trigger in a custom plugin.
-
-### Deploying with private git submodules
-
-Dokku uses git locally (i.e. not a docker image) to build its own copy of your app repo, including submodules. This is done as the `dokku` user. Therefore, in order to deploy private git submodules, you'll need to drop your deploy key in `/home/dokku/.ssh/` and potentially add github.com (or your VCS host key) into `/home/dokku/.ssh/known_hosts`. The following test should help confirm you've done it correctly.
-
-```shell
-su - dokku
-ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts
-ssh -T git@github.com
-```
-
-Note that if the buildpack or dockerfile build process require ssh key access for other reasons, the above may not always apply.
-
-### Specifying a custom buildpack
-
-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.
-
-To use a specific buildpack, you can run the following dokku command:
-
-```shell
-# replace APP with the name of your application
-# replace REPOSITORY_URL with your buildpack's url
-dokku config:set APP BUILDPACK_URL=REPOSITORY_URL
-```
-
-Please check the documentation for your particular build pack as you may need to include configuration files (such as a Procfile) in your project root.
-
-## Deploying to subdomains
-
-The name of remote repository is used as the name of application to be deployed, as for example above:
-
-    $ git remote add dokku dokku@dokku.me:ruby-rails-sample
-    $ git push dokku master
-
-Is deployed to,
-
-    remote: -----> Application deployed:
-    remote:        http://ruby-rails-sample.dokku.me
-
-You can also specify fully qualified names, say `app.dokku.me`, as
-
-    $ git remote add dokku dokku@dokku.me:app.dokku.me
-    $ git push dokku master
-
-So, after deployment the application will be available at,
-
-    remote: -----> Application deployed:
-    remote:        http://app.dokku.me
-
-This is in particular useful, then you want to deploy to root domain, as
-
-    $ git remote add dokku dokku@dokku.me:dokku.me
-    $ git push dokku master
-
-    ... deployment ...
-
-    remote: -----> Application deployed:
-    remote:        http://dokku.me
-
-## Dokku/Docker Container Management Compatibility
-
-Dokku is, at its core, a docker container manager. Thus, it does not necessarily play well with other out-of-band processes interacting with the docker daemon. One thing to note as in [issue #1220](https://github.com/progrium/dokku/issues/1220), dokku executes a cleanup function prior to every deployment. This function removes all exited containers and all 'unattached' images.
