-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of experience,

-## Backup and Migration Tutorial
+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.
+
+## TLDR
+
+> 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 apps can be rebuilt. Please consult the [process management documentation](/docs/processes/process-management.md#rebuilding-apps) for more information on how to rebuild apps.
+
+## 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.

-## Volumes and Static Assets
+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.
 
-See the [persistent storage documentation](/docs/advanced-usage/persistent-storage.md) for more details.
+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.

+
+- 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

-## `app.json` deployment tasks
+### Changing the `app.json` location
+
+When deploying a monorepo, it may be desirable to specify the specific path of the `app.json` file to use for a given app. This can be done via the `app-json:set` command. If a value is specified and that file does not exist within the repository, Dokku will continue the build process as if the repository has no `app.json` file.
+
+```shell
+dokku app-json:set node-js-app appjson-path second-app.json
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku app-json:set node-js-app appjson-path
+```
+
+The `appjson-path` property can also be set globally. The global default is `app.json`, and the global value is used when no app-specific value is set.
+
+```shell

 ## Usage
 
-This example demonstrates how to mount the recommended directory to `/storage` inside an application called `node-js-app`:
+### Creating storage directories
+
+> New as of 0.25.5
+
+A storage directory can be created with the `storage:ensure-directory` command. This command will create a subdirectory in the recommended `/var/lib/dokku/data/storage` path - created during Dokku installation - and prepare it for use with an 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 storage:ensure-directory lollipop
 ```
 
-Dokku will then mount the shared contents of `/var/lib/dokku/data/storage` to `/storage` inside the container.
+```
+-----> Ensuring /var/lib/dokku/data/storage/lollipop exists
+       Setting directory ownership to 32767:32767
+       Directory ready for mounting
+```
 
-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.
+By default, permissions are set for usage with Herokuish buildpacks. These permissions can be changed via the `--chown` option according to the following table:
+
+- `--chown herokuish` (default): Use `32767:32767` as the folder permissions.
+  - This is used for apps deployed with Buildpacks via Herokuish.
+- `--chown heroku`: Use `1000:1000` as the folder permissions.
+  - This is used for apps deployed with Cloud Native Buildpacks using the `heroku/buildpacks` builder.
+- `--chown packeto`: Use `2000:2000` as the folder permissions.
+  - This is used for apps deployed with Cloud Native Buildpacks using the `cloudfoundry/cnb` or `packeto` builders.
+- `--chown false`: Skips the `chown` call.
+
+Users deploying via Dockerfile will want to specify `--chown false` and manually `chown` the created directory if the user and/or group id  of the runnning process in the deployed container do not correspond to any of the above options.
+
+> Warning: Failing to set the correct directory ownership may result in issues in persisting files written to the mounted storage directory.
+
+### Mounting storage into apps
+
+Dokku supports mounting both explicit host paths as well as docker volumes via the `storage:mount` command. This takes two arguments, an app name and a `host-path:container-path` or `docker-volume:container-path` combination.
+
+```shell
+# mount the directory into your container's /app/storage directory, relative to the container root (/)
+# explicit host paths _must_ exist prior to usage.
+dokku storage:mount node-js-app /var/lib/dokku/data/storage/node-js-app:/app/storage
+
+# mount the docker volume into your container's /app/storage directory, relative to the container root (/)
+# docker volumes _must_ exist prior to usage.
+dokku storage:mount node-js-app some-docker-volume:/app/storage
+```
+
+In the first example, Dokku will then mount the shared contents of `/var/lib/dokku/data/storage/node-js-app` to `/app/storage` inside the container.  The mount point is *not* relative to your app's working directory, and is instead relative to the root (`/`) of the container. Mounts are only available for containers created via `run` and by the deploy process, and not during the build process. In addition, the host path is never auto-created by either Dokku or Docker, and should be an explicit path, not one relative to the current working directory.
+
+> If the `/storage` path within the container had pre-existing content, the container files will be over-written. This may be an issue for users that create assets at build time but then mount a directory at the same place during runtime. Files are not merged.
+
+Once persistent storage is mounted, the app requires a restart. See the [process scaling documentation](/docs/processes/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.
+### Unmounting storage
+
+If an app no longer requires a mounted volume or directory, the `storage:unmount` command can be called. This takes the same arguments as the `storage:mount` command, an app name and a `host-path:container-path` or `docker-volume:container-path` combination.
 
 ```shell
-# creating storage for the app 'node-js-app'
-mkdir -p  /var/lib/dokku/data/storage/node-js-app
+# unmount the directory from your container's /app/storage directory, relative to the container root (/)
+dokku storage:unmount node-js-app /var/lib/dokku/data/storage/node-js-app:/app/storage
 
-# 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
+# unmount the docker volume from your container's /app/storage directory, relative to the container root (/)
+dokku storage:unmount node-js-app some-docker-volume:/app/storage
 ```
 
-You can mount one or more directories as desired by following the above pattern.
+Once persistent storage is unmounted, the app requires a restart. See the [process scaling documentation](/docs/processes/process-management.md) for more information.

+
 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.

-You can also uninstall a third-party plugin using the `plugin:uninstall` command:
+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.

+```
+
+The registry plugin enables interacting with remote registries, which is useful when either deploying images via `git:from-image` or when interacting with custom schedulers to deploy built image artifacts.
+
+## Usage
+
+### Logging into a registry
+
+The `registry:login` command can be used to log into a docker registry. The following are examples for logging into various common registries:
+
+```shell
+# hub.docker.com
+dokku registry:login docker.io $USERNAME $PASSWORD
+
+# digitalocean
+# the username and password are both defined as the same api token
+dokku registry:login registry.digitalocean.com $DIGITALOCEAN_API_TOKEN $DIGITALOCEAN_API_TOKEN
+
+# github container registry
+# see the following link for information on retrieving a personal access token
+#   https://docs.github.com/en/packages/guides/pushing-and-pulling-docker-images#authenticating-to-github-container-registry
+dokku registry:login ghcr.io $USERNAME $REGISTRY_PAT_TOKEN
+
+# quay
+# a robot user may be used to login
+dokku registry:login quay.io $USERNAME $PASSWORD
+```
+
+For security reasons, the password may also be specified as stdin by specifying the `--password-stdin` flag. This is supported regardless of the registry being logged into.
+
+```shell
+echo "$PASSWORD" | dokku registry:login --password-stdin docker.io $USERNAME
+```
+
+For certain Docker registries - such as Amazon ECR or Google's GCR registries - users may instead wish to use a docker credential helper to automatically authenticate against a server; please see the documentation regarding the credential helper in question for further setup instructions.
+
+### Setting a remote server
+
+To specify a remote server registry for pushes, set the `server` property via the `registry:set` command. The default value for this property is empty string. Setting the value to `docker.io` or `hub.docker.com` will result in the computed value being empty string (as that is the default, implicit registry), while any non-zero length value will have a `/` appended to it if there is not one already.
+
+```shell
+dokku registry:set node-js-app server docker.io
+```
+
+This property can be set for a single app or globally via the `--global` flag. When set globally, the app-specific value will always overide the global value. The default global value for this property is empty string.
+
+```shell
+dokku registry:set --global server docker.io
+```
+
+Setting the property value to an empty string will reset the value to the system default. Resetting the value can be done per app or globally.
+
+```shell
+# per-app
+dokku registry:set node-js-app server
+
+# globally
+dokku registry:set --global server
+```
+
+The following are the values that should be used for common remote servers:
+
+- Amazon Elastic Container Registry:
+  - value: `$AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com/`
+  - notes: The `$AWS_ACCOUNT_ID` and `$AWS_REGION` should match the values for your account and region, respectively. Additionally, an IAM profile that allows `push` access to the repository specified by `image-repo` should be attached to your Dokku server.
+- Azure Container Registry:
+  - value `$REGISTRY_NAME.azurecr.io/`
+  - notes: The `$AKS_REGISTRY_NAME` should match the name of the registry created on your account.
+- Docker Hub:
+  - value: `docker.io/`
+  - notes: Requires owning the namespace used in the `image-repo` value.
+- Digitalocean:
+  - value: `registry.digitalocean.com/`
+  - notes: Requires setting the correct `image-repo` value for your registry.
+- Github Container Registry:
+  - value: `ghcr.io/`
+  - notes: Requires that the authenticated user has access to the namespace used in the `image-repo` value.
+- Quay.io:
+  - value: `quay.io/`
+
+### Specifying an image repository name
+
+By default, Dokku uses the value `dokku/$APP_NAME` as the image repository that is pushed and deployed. For certain registries, the `dokku` namespace may not be available to your user. In these cases, the value can be set by changing the value of the `image-repo` property via the `registry:set` command.
+
+```shell
+dokku registry:set node-js-app image-repo my-awesome-prefix/node-js-app
+```
+
+Setting the property value to an empty string will reset the value to the system default. Resetting the value has to be done per-app.
+
+```shell
+# per-app
+dokku registry:set node-js-app push-on-release
+```
+
+### Pushing images on build
+
+To push the image on release, set the `push-on-release` property to `true` via the `registry:set` command. The default value for this property is `false`. Setting the property to `true` will result in the image being tagged with an ID that is incremented with every release. This tag will be what is used for running app code.
+
+```shell
+dokku registry:set node-js-app push-on-release true
+```
+
+This property can be set for a single app or globally via the `--global` flag. When set globally, the app-specific value will always overide the global value. The default global value for this property is `false`.
+
+```shell
+dokku registry:set --global push-on-release true
+```
+
+Setting the property value to an empty string will reset the value to the system default. Resetting the value can be done per app or globally.
+
+```shell
+# per-app

-> Subcommands new as of 0.12.12
-
-```
-scheduler-docker-local:report [<app>] [<flag>]              # Displays a scheduler-docker-local report for one or more apps
-scheduler-docker-local:set <app> <key> (<value>)            # Set or clear a scheduler-docker-local property for an app
-```
-
-> 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.
-- memory: (docker option: `--memory`) and should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes)
-- memory-swap: (docker option: `--memory-swap`) and should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes)
-
-### 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.
+
+### 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)
+
+### Removed 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`.

+## 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.

+- The `plugin:list` command no longer outputs the version for the `plugn` binary.
+- Users building docker images that run Dokku will need to use a new sudoer wrapper for the `docker-image-labeler` binary to work correctly. A reference version has been placed in the `docker` skeleton directory. This should only impact platform developers, and users of our Docker image will already have the file available.
+- The `dokku` user's cron is now in use by Dokku itself. Customizations will be overwritten. Users are encouraged to use a cron entry in `/etc/cron.d/dokku` to avoid this issue.
+- As of 0.23.0, Dokku will now inject the `max-size` log driver option for applications. This is restricted to app-configured log driver values empty, `local` or `json-file` in 0.23.1 to increase setup compatibility. Users who configure alternative log drivers at the system level will need to either set the global `max-size` property to `unlimited` or switch to the built-in `vector` logging support.

+
+## Deprecations
+
+- The 1.0.0 release of Dokku will no longer select buildpack builders over dockerfile builders if both builders match. Instead, Dokku will choose the first builder that responds to the `builder-detect` trigger. Users that wish to use a specific builder may set a builder using the `builder:set` command, which will force Dokku to use the specified builder regardless of what might be auto-detected.
+- The `tags` plugin is deprecated in favor of the [`git:from-image`](/docs/deployment/methods/git.md#initializing-an-app-repository-from-a-docker-image) command.

+## Registry Plugin
+
+The [dokku-registry](https://github.com/dokku/dokku-registry) plugin is now built-in. This comes with a few changes:
+
+- Builder plugins should call `post-release-builder` at the end of the build.
+- The `push` and `pull` command are not implemented. Users wishing to deploy a remote image should use `git:from-image`. Image pushing is not available at this time.
+- At this time, remote docker repositories are not automatically created for AWS, and users must create those repositories for their applications as necessary. This may be implemented in the future.
+- Docker images are only pushed when configured to do so. See the [registry management documentation](/docs/deployment/registry-management.md) for more details.
+
+## Other
+
+### Changes
+
+- The network plugin can now set an `initial-network` for all containers on creation. This is a replacement for specifying the `--network` flag via the `docker-options` plugin. Please see the [network documentation](/docs/networking/network.md#attaching-an-app-to-a-network) for more information.
+- The `dokku run` command now always removes the ephemeral container on exit. Users that need a persistent container should instead specify a `console` process type in their `Procfile` specifying an available shell (usually either `bash` or `sh`) and scale that container appropriately.
+- The `pre-deploy` plugin trigger is now called internally by Dokku. Scheduler plugins should avoid calling this trigger, as any image changes introduced by subsequent trigger calls will be ignored.
+- The default image used for Herokuish Buildpack builds is now `gliderlabs/herokuish:latest-20`, and is based on both the `heroku-20` stack as well as Ubuntu 20.04. Users that wish to stick with the old, `heroku-18`/Ubuntu 18.04 builder may specify `gliderlabs/herokuish:latest-18` as their builder image. Please see the [herokuish buildpack deployment documentation](/docs/deployment/builders/herokuish-buildpacks.md#customizing-the-buildpack-stack-builder) for more information on how to specify a custom buildpack stack builder.
+  - This change does not impact any users of Cloud Native Buildpacks.
+- We fixed an issue that required extracting Procfiles at the beginning of a deploy. Due to this change, a `Dockerfile` app contains a `Procfile` that does not specify a `web` process will fail to start. Usage of a `Procfile` with _only_ a `release` command should be replaced with a `scripts.dokku.postdeploy` deployment task in the `app.json` file. The alternative is to define the `web` process in the `Procfile`. See the [deployment task documentation](/docs/advanced-usage/deployment-tasks.md) for more information.
+
+### Deprecations
+
+- In previous versions of Dokku, the only way to specify a custom `Dockerfile` was to use the `docker-options` plugin to set the `--file` flag for a docker build. As of 0.25.0, the `builder-dockerfile:set` command should be used instead, as outlined in the [docs here](/docs/deployment/builders/dockerfiles.md#changingthe-dockerfile-location). Usage of the old method should be migrated to the new method.
+- The `--rm` and `--rm-container` flags may be specified but no longer have any effect on `dokku run`.
+- The `--detach` flag is deprecated in favor of the `run:detached` command.
+- The `DOKKU_SCALE` file is deprecated. Please see the [process management documentation](/docs/processes/process-management.md#manually-managing-process-scaling) for more information on it's replacement with the `formation` key of the `app.json` file.
+- The hooks `post-release-buildpack`, `post-release-dockerfile`, and `post-release-pack` are deprecated in favor of `post-release-builder`. See the [plugin triggers documentation](https://dokku.com/docs/development/plugin-triggers/#post-release-builder) for more details.
+
+## Removals
+
+- As of April 2021, Ubuntu 16.04 is no longer an LTS release, and support has been removed. Packages may still install on older versions of Ubuntu, but are no longer tested, and therefore no support will be provided.
+- The web installer has been removed. Users are now required to setup Dokku via cli commands. This change was made to combat potential security issues where users ignored the web installer, allowing unauthorized users to add their keys to the host.
+- The `scheduler-docker-cleanup` plugin trigger has been removed from the scheduler interface, and is no longer invoked.

 Given the constraints, running Dokku commands remotely via SSH is fine. For certain configurations, the extra complication of manually invoking ssh can be a burden.
 
-While Dokku does not yet have an official client, there are a multitude of ways in which you can interact with your Dokku installation. The easiest is to use the **bash** client, though you may wish to use another.
+The easiest way to interact with Dokku remotely is by using the official client. Documented below are the various clients that you may wish to use.
 
-## (bash, zsh, etc.) `dokku_client.sh`
+## Official Client
 
-Of all methods, this is the *most* official method of interacting with your Dokku installation. It is a bash script that interacts with a remote Dokku installation via ssh. It is available in `contrib/dokku_client.sh` in the root of the Dokku repository.
-
-To install, simply clone the Dokku repository down and add the `dokku` alias pointing at the script:
-
-```shell
-git clone git@github.com:dokku/dokku.git ~/.dokku
-
-# optional: make sure that the dokku_client.sh version matches your Dokku version
-cd ~/.dokku
-git checkout <tag/branch>
-
-# add the following to either your
-# .bashrc, .bash_profile, or .profile file
-alias dokku='$HOME/.dokku/contrib/dokku_client.sh'
-```
-
-Alternatively, if using another shell such as **zsh**, create an alias command which invokes the script using **bash**:
-
-```shell
-# zsh: add the following to either .zshenv or .zshrc
-alias dokku='bash $HOME/.dokku/contrib/dokku_client.sh'
-
-# fish: add the following to ~/.config/fish/config.fish
-alias dokku 'bash $HOME/.dokku/contrib/dokku_client.sh'
-
-# csh: add the following to .cshrc
-alias dokku 'bash $HOME/.dokku/contrib/dokku_client.sh'
-```
-
-Configure the `DOKKU_HOST` environment variable or run `dokku` from a repository with a git remote named `dokku` pointed at your Dokku host in order to use the script as normal.
-
-You can also configure a `DOKKU_PORT` environment variable if you are running ssh on a non-standard port. This defaults to `22`.
+See the [remote commands documentation](/docs/deployment/remote-commands.md) for more information on how to install and use the official client.

-deploy:

-  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.

 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_PROXY_PORT` and/or `DOKKU_PROXY_SSL_PORT` (for services configured to use SSL.)

 ## Default site
 
-By default, Dokku will route any received request with an unknown HOST header value to the lexicographically first site in the nginx config stack. If this is not the desired behavior, you may want to add the following configuration to the global nginx configuration.
-
-Create the file at `/etc/nginx/conf.d/00-default-vhost.conf`:
-
-```nginx
-server {
-    listen 80 default_server;
-    server_name _;
-    access_log off;
-    return 410;
-}
-
-# To handle HTTPS requests, you can uncomment the following section.
-#
-# Please note that in order to let this work as expected, you need a valid
-# SSL certificate for any domains being served. Browsers will show SSL
-# errors in all other cases.
-#
-# Note that the key and certificate files in the below example need to
-# be copied into /etc/nginx/ssl/ folder.
-#
-# server {
-#     listen 443 ssl;
-#     server_name _;
-#     ssl_certificate /etc/nginx/ssl/cert.crt;
-#     ssl_certificate_key /etc/nginx/ssl/cert.key;
-#     access_log off;
-#     return 410;
-# }
-```
-
-Make sure to reload nginx after creating this file by running `service nginx reload`.
-
-This will catch all unknown HOST header values and return a `410 Gone` response. You can replace the `return 410;` with `return 444;` which will cause nginx to not respond to requests that do not match known domains (connection refused).
-
-The configuration file must be loaded before `/etc/nginx/conf.d/dokku.conf`, so it can not be arranged as a vhost in `/etc/nginx/sites-enabled` that is only processed afterwards.
-
-Alternatively, you may push an app to your Dokku host with a name like "00-default". As long as it lists first in `ls /home/dokku/*/nginx.conf | head`, it will be used as the default nginx vhost.
+This is specific to your proxy plugin of choice. See the [nginx documentation](/docs/configuration/nginx.md#default-site) for more information on how to configure this for the default nginx proxy implementation.

-## Checking access logs
+## Usage
+
+### Request Proxying
+
+By default, the `web` process is the only process proxied by the nginx proxy implementation. Proxying to other process types may be handled by a custom `nginx.conf.sigil` file, as generally described [below](/docs/configuration/nginx.md#customizing-the-nginx-configuration)
+
+Nginx will proxy the requests in a [round-robin balancing fashion](http://nginx.org/en/docs/http/ngx_http_upstream_module.html#upstream) to the different deployed (scaled) containers running the `web` proctype. This way, the host's resources can be fully leveraged for single-threaded applications (e.g. `dokku ps:scale node-js-app web=4` on a 4-core machine)
+
+### 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.
+
+#### Globally disabling the HSTS Header
+
+HSTS Header can be disabled for all apps by setting the `hsts` property to false after passing the `--global` flag to `nginx:set`. Changing this value globally or on a per-app basis will require rebuilding the nginx config via the `proxy:build-config` command.
+
+```shell
+dokku nginx:set --global hsts false
+```
+
+Once the HSTS setting is disabled globally, it can be re-enabled on a per-app basis by setting the `hsts` property as normal.
+
+```shell
+dokku nginx:set node-js-app hsts true
+```

-## Regenerating nginx config
+### Changing log path
 
-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.
+> New as of 0.20.1
+
+The path to where log files are stored can be changed by calling the `nginx:set` command with the following options:
+
+- `access-log-path` (type: string, default: `${NGINX_LOG_ROOT}/${APP}-access.log`): Log path for nginx access logs
+- `error-log-path` (type: string, default: `${NGINX_LOG_ROOT}/${APP}-error.log`): Log path for nginx error logs
+
+The defaults should not be changed without verifying that the paths will be writeable by nginx. However, this setting is useful for enabling or disabling logging by setting the values to `off`.
 
 ```shell
-dokku nginx:build-config node-js-app
+dokku nginx:set node-js-app access-log-path off

-## Validating nginx configs
-
-It may be desired to validate an nginx config outside of the deployment process. To do so, run the `nginx:validate` 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.
+The default value may be set by passing an empty value for the option:
 
 ```shell
-dokku nginx:validate
+dokku nginx:set node-js-app access-log-path
+dokku nginx:set node-js-app error-log-path
 ```
 
-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` command is the exit code of `nginx -t` against the server's real nginx config.
+In all cases, the nginx config must be regenerated after setting the above values.
 
-The `nginx:validate` command also takes an optional `--clean` flag. If specified, invalid nginx configs will be removed.
+### Changing log format
+
+> New as of 0.22.0
+
+The format of the access log can be changed by calling the `nginx:set` command as follows:
+
+```shell
+dokku nginx:set node-js-app access-log-format custom-format
+```
+
+Prior to changing the log-format, log formats should be specified at a file such as `/etc/nginx/conf.d/00-log-formats.conf`. This will ensure they are available within your app's nginx context. For instance, the following may be added to the above file. It only needs to be specified once to be used for all apps.
+
+```nginx
+# /etc/nginx/conf.d/00-log-formats.conf
+# escape=json was added in nginx 1.11.8
+log_format json_combined escape=json
+  '{'
+    '"time_local":"$time_local",'
+    '"remote_addr":"$remote_addr",'
+    '"remote_user":"$remote_user",'
+    '"request":"$request",'
+    '"status":"$status",'
+    '"body_bytes_sent":"$body_bytes_sent",'
+    '"request_time":"$request_time",'
+    '"http_referrer":"$http_referer",'
+    '"http_user_agent":"$http_user_agent"'
+  '}';
+```
+
+Next, the format should be set for the given app.
+
+```shell
+dokku nginx:set node-js-app access-log-format json_combined
+```
+
+Finally, a proxy rebuild will change the format as desired.
+
+```shell
+dokku proxy:build-config node-js-app
+```
+
+### Specifying a read timeout
+
+> New as of 0.21.0
+
+When proxying requests to your applications, it may be useful to specify a proxy read timeout. This can be done via the `nginx:set` command as follows:
+
+```shell
+dokku nginx:set node-js-app proxy-read-timeout 120s
+```
+
+The default value is `60s`, and all numeric values _must_ have a trailing time value specified (`s` for seconds, `m` for minutes).
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku nginx:set node-js-app proxy-read-timeout
+```
+
+In all cases, the nginx config must be regenerated after setting the above value.
+
+### Specifying a custom client_max_body_size
+
+> New as of 0.23.0
+
+Users can override the default `client_max_body_size` value - which limits file uploads - via `nginx:set`. Changing this value will only apply to every `server` stanza of the default `nginx.conf.sigil`; users of custom `nginx.conf.sigil` files must update their templates to support the new value.
+
+```shell
+dokku nginx:set node-js-app client-max-body-size 50m
+```
+
+The default value is empty string, which will result in nginx falling back to any configured, higher-level defaults (or `1m` if unconfigued; all numerical values _must_ have a size unit specified (`k` for kilobytes, `m` for megabytes).
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku nginx:set node-js-app client-max-body-size
+```
+
+In all cases, the nginx config must be regenerated after setting the above value.
+
+Changing this value when using the PHP buildpack (or any other buildpack that uses an intermediary server) will require changing the value in the server config shipped with that buildpack. Consult your buildpack documentation for further details.
+
+### 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

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 --clean
+dokku nginx:validate-config --clean
 ```
 
 The `--clean` flag may also be specified for a given app:
 
 ```shell
-dokku nginx:validate node-js-app --clean
+dokku nginx:validate-config node-js-app --clean
 ```

+builder:report [<app>] [<flag>]   # Displays a builder report for one or more apps
+builder:set <app> <key> (<value>) # Set or clear a builder property for an app
+```
+
+Builders are a way of customizing how an app is built from a source, allowing users flexibility in how artifacts are created for later scheduling.
+
+## Usage
+
+### Builder selection
+
+Dokku supports the following built-in builders:
+
+- `builder-dockerfile`: Builds apps using a `Dockerfile` via `docker build`. See the [dockerfile builder documentation](/docs/deployment/builders/dockerfiles.md) for more information on how this builder functions.
+- `builder-herokuish`: Builds apps with Heroku's v2a Buildpack specification via `gliderlabs/herokuish`. See the [herokuish builder documentation](/docs/deployment/builders/herokuish-buildpacks.md) for more information on how this builder functions.
+- `builder-null`: Does nothing during the build phase. See the [null builder documentation](/docs/deployment/builders/null.md) for more information on how this builder functions.
+- `builder-pack`: Builds apps with Cloud Native Buildpacks via the `pack-cli`  tool. See the [cloud native buildpacks builder documentation](/docs/deployment/builders/cloud-native-buildpacks.md) for more information on how this builder functions.
+
+Builders run a detection script against a source code repository, and the first detected builder will be used to build the app artifact. The exception to this is when a `Dockerfile` is detected and the app is also able to use either `herokuish` or `pack-cli` for building, in which case one of the latter will be chosen.
+
+### Overriding the auto-selected builder
+
+If desired, the builder can be specified via the `builder:set` command by speifying a value for `selected`. The selected builder will always be used.
+
+```shell
+dokku builder:set node-js-app selected dockerfile
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku builder:set node-js-app selected
+```
+
+The `selected` property can also be set globally. The global default is an empty string, and auto-detection will be performed when no value is set per-app or globally.
+
+```shell
+dokku builder:set --global selected herokuish
+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell
+dokku builder:set --global selected
+```
+
+#### Changing the build directory
+
+> Warning: Please keep in mind that setting a custom build directory will result in loss of any changes to the top-level directory, such as the `git.keep-git-dir` property.
+
+When deploying a monorepo, it may be desirable to specify the specific build directory to use for a given app. This can be done via the `builder:set` command. If a value is specified and that directory does not exist within the repository, the build will fail.
+
+```shell
+dokku builder:set node-js-app build-dir app2
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku builder:set node-js-app build-dir
+```
+
+The `build-dir` property can also be set globally. The global default is empty string, and the global value is used when no app-specific value is set.
+
+```shell
+dokku builder:set --global build-dir app2
+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell
+dokku builder:set --global build-dir
+```
+
+### Displaying builder reports for an app
+
+You can get a report about the app's builder status using the `builder:report` command:
+
+```shell

+```
+

+```
+
+You can pass flags which will output only the value of the specific information you want. For example:
+
+```shell
+dokku builder:report node-js-app --builder-selected
+```
+
+### Custom builders
+
+To create a custom builder, the following triggers must be implemented:
+
+- `builder-build`:
+  - arguments: `BUILDER_TYPE` `APP` `SOURCECODE_WORK_DIR`
+  - description: Creates a docker image named with the output of `common#get_app_image_name $APP`.
+- `builder-detect`:
+  - arguments: `APP` `SOURCECODE_WORK_DIR`
+  - description: Outputs the name of the builder (without the `builder-` prefix) to use to build the app.
+- `builder-release`:
+  - arguments: `BUILDER_TYPE` `APP` `IMAGE_AG`
+  - description: A post-build, pre-release trigger that can be used to post-process the image. Usually simply tags and labels the image appropriately.
+
+Custom plugins names _must_ have the prefix `builder-` or builder overriding via `builder:set` may not function as expected.
+
+Builders can use any tools available on the system to build the docker image, and may even be used to schedule building off-server. The only current requirement is that the image must exist on the server at the end of the `builder-build` command, though this requirement may be relaxed in a future release.
+
+For a simple example of how to implement this trigger, see `builder-pack`, which utilizes a cli tool - `pack-cli` - to generate an OCI image that is compatible with Docker and can be scheduled by the official scheduling plugins.

+# Cloud Native Buildpacks (Experimental)
+
+> New as of 0.22.0
+
+```
+buildpacks:set-property [--global|<app>] <key> <value>  # Set or clear a buildpacks property for an app
+```
+
+Cloud Native Buildpacks are an evolution over the Buildpacks technology provided by the Herokuish builder. See the [herokuish buildpacks documentation](/docs/deployment/builders/herokuish-buildpacks.md) for more information on how to clear buildpack build cache for an application.
+
+> Warning: This functionality uses the `pack` cli from the [Cloud Native Buildpacks](https://buildpacks.io) project to build apps. As the integration is experimental in Dokku, it is likely to change over time.
+
+## Usage
+
+### Requirements
+
+The `pack` cli tool is not included by default with Dokku or as a dependency. It must also be installed as shown on [this page](https://buildpacks.io/docs/tools/pack/).
+
+Builds will proceed with the `pack` cli for the app from then on.
+
+### Caveats
+
+As this functionality is highly experimental, there are a number of caveats. Please note that not all issuesare listed below.
+
+- Specifying specific buildpacks is not currently possible.
+  - A future release will add support for specifying buildpacks via the `buildpacks` plugin.
+- There is currently no way to specify extra arguments for `pack` cli invocations.
+  - A future release will add support for injecting extra arguments during the build process.
+- The default process type is `web`.
+- Build cache is stored in Docker volumes instead of on disk. As such, `repo:purge-cache` currently has no effect.
+  - A future version will add integration with the `repo` plugin.
+- `pack` is not currently included with Dokku, nor is it added as a package dependency.
+  - A future version will include it as a package dependency.
+
+### Detection
+
+This builder will be auto-detected in either the following cases:
+
+- The `DOKKU_CNB_EXPERIMENTAL` app environment variable is set to `1`.
+  ```shell
+  dokku config:set --no-restart node-js-app DOKKU_CNB_EXPERIMENTAL=1
+  ```
+- A `project.toml` file exists in the root of the app repository.
+  - This file is consumed by `pack-cli` and used to describe how the app is built.
+
+The builder can also be specified via the `builder:set` command:
+
+```shell
+dokku builder:set node-js-app selected pack
+```
+
+> Dokku will only select the `dockerfile` builder if both the `herokuish` and `pack` builders are not detected and a Dockerfile exists. See the [dockerfile builder documentation](/docs/deployment/builders/dockerfiles.md) for more information on how that builder functions.
+
+### Changing the `project.toml` location
+
+When deploying a monorepo, it may be desirable to specify the specific path of the `project.toml` file to use for a given app. This can be done via the `builder-pack:set` command. If a value other than `project.toml` is specified and that file does not exist in the app's build directory, Dokku will continue the build process as if the repository has no `project.toml`.
+
+```shell
+dokku builder-pack:set node-js-app projecttoml-path project2.toml
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku builder-pack:set node-js-app projecttoml-path
+```
+
+The `projecttoml-path` property can also be set globally. The global default is `project.toml`, and the global value is used when no app-specific value is set.
+
+```shell
+dokku builder-pack:set --global projecttoml-path project2.toml
+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell
+dokku builder-pack:set --global projecttoml-path
+```
+
+### Displaying builder-pack reports for an app
+
+> New as of 0.25.0

+```shell

+```
+
+```

+```
+
+### Customizing the Buildpack stack builder
+
+> New as of 0.23.0
+
+The default stack builder in use by CNB buildpacks in Dokku is based on `heroku/buildpacks`. Users may desire to switch the stack builder to a custom version, either to update the operating system or to customize packages included with the stack builder. This can be performed via the `buildpacks:set-property` command.
+
+```shell
+dokku buildpacks:set-property node-js-app stack paketobuildpacks/build:base-cnb
+```
+
+The specified stack builder can also be unset by omitting the name of the stack builder when calling `buildpacks:set-property`.
+
+```shell
+dokku buildpacks:set-property node-js-app stack
+```
+
+A change in the stack builder value will execute the `post-stack-set` trigger.
+
+Finally, stack builders can be set or unset globally as a fallback. This will take precedence over a globally set `DOKKU_CNB_BUILDER` environment variable (`heroku/buildpacks` by default).
+
+```shell
+# set globally
+dokku buildpacks:set-property --global stack paketobuildpacks/build:base-cnb
+
+# unset globally
+dokku buildpacks:set-property --global stack
+```

+# Dockerfile Deployment
+
+> New as of 0.3.15
+
+While Dokku normally defaults to using [Heroku buildpacks](https://devcenter.heroku.com/articles/buildpacks) for deployment, you can also use Docker's native `Dockerfile` system to define a container.
+
+> Dockerfile support is considered a *power user* feature. By using Dockerfile-based deployment, you agree that you will not have the same comfort as that enjoyed by buildpack users, and Dokku features may work differently. Differences between the two systems will be documented here.
+
+## Usage
+
+### Detection
+
+This builder will be auto-detected in the following case:
+
+- A `Dockerfile` exists in the root of the app repository.
+
+Dokku will only select the `dockerfile` builder if both the `herokuish` and `pack` builders are not detected and a Dockerfile exists. For more information on how those are detected, see the following links:
+
+- [Cloud Native Buildpacks documentation](/docs/deployment/builders/cloud-native-buildpacks.md#detection)
+- [Herokuish documentation](/docs/deployment/builders/herokuish-buildpacks.md#detection)
+
+### Switching from buildpack deployments
+
+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 
+```
+
+### Changing the `Dockerfile` location
+
+> The previous method to perform this - via `docker-options:add` - should be removed in favor of the `builder-dockerfile:set` command outlined here.
+
+When deploying a monorepo, it may be desirable to specify the specific path of the `Dockerfile` file to use for a given app. This can be done via the `builder-dockerfile:set` command. If a value is specified and that file does not exist in the app's build directory, then the build will fail.
+
+```shell
+dokku builder-dockerfile:set node-js-app dockerfile-path Dockerfile2
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku builder-dockerfile:set node-js-app dockerfile-path
+```
+
+The `dockerfile-path` property can also be set globally. The global default is `Dockerfile`, and the global value is used when no app-specific value is set.
+
+```shell
+dokku builder-dockerfile:set --global dockerfile-path Dockerfile2
+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell
+dokku builder-dockerfile:set --global dockerfile-path
+```
+
+### Displaying builder-dockerfile reports for an app
+
+> New as of 0.25.0
+
+You can get a report about the app's storage status using the `builder-dockerfile:report` command:
+
+```shell

+```

+```
+
+You can run the command for a specific app also.
+
+```shell

+```
+
+```
+=====> node-js-app builder-dockerfile information
+       Builder-dockerfile computed dockerfile path: Dockerfile2
+       Builder-dockerfile global dockerfile path:   Dockerfile
+       Builder-dockerfile dockerfile path:          Dockerfile2
+```
+
+You can pass flags which will output only the value of the specific information you want. For example:
+
+```shell
+dokku builder-dockerfile:report node-js-app --builder-dockerfile-dockerfile-path
+```
+
+```
+Dockerfile2
+```
+
+### Build-time configuration variables
+
+For security reasons - and as per [Docker recommendations](https://github.com/docker/docker/issues/13490) - Dockerfile-based deploys have variables available only during runtime.
+
+For users that require customization in the `build` phase, you may use build arguments via the [docker-options plugin](docs/advanced-usage/docker-options.md):
+
+```shell
+dokku docker-options:add node-js-app build '--build-arg NODE_ENV=production'
+```
+
+Once set, the Dockerfile usage would be as follows:
+
+```Dockerfile
+FROM ubuntu:18.04
+
+# set the argument default
+ARG NODE_ENV=production
+
+# use the argument
+RUN echo $NODE_ENV
+```
+
+You may also set the argument as an environment variable
+
+```Dockerfile
+FROM ubuntu:18.04
+
+# set the argument default
+ARG NODE_ENV=production
+
+# assign it to an environment variable
+# we can wrap the variable in brackets
+ENV NODE_ENV ${NODE_ENV}
+
+# or omit them completely
+
+# use the argument
+RUN echo $NODE_ENV
+```
+
+### Building images with Docker Buildkit
+
+If your Dockerfile is using Docker engine's [buildkit](https://docs.docker.com/develop/develop-images/build_enhancements/) (not to be confused with buildpacks), then the `DOCKER_BUILDKIT=1` environment variable needs to be set. Additionally, complete build log output can be forced via `BUILDKIT_PROGRESS=plain`. Both of these environment variables can be set as follows:
+
+```shell
+echo "export DOCKER_BUILDKIT=1" | sudo tee -a /etc/default/dokku
+echo "export BUILDKIT_PROGRESS=plain" | sudo tee -a /etc/default/dokku
+```
+
+#### Buildkit directory caching
+
+Buildkit implements the `RUN --mount` option, enabling mount directory caches for `RUN` directives. The following is an example that mounts debian packaging related directories, which can speed up fetching of remote package data.
+
+```Dockerfile
+FROM debian:latest
+RUN --mount=target=/var/lib/apt/lists,type=cache \
+    --mount=target=/var/cache/apt,type=cache \
+    apt-get update \
+ && DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends \
+      git
+```
+
+Mount cache targets may vary depending on the tool in use, and users are encouraged to investigate the directories that apply for their language and framework.
+
+You would adjust the cache directory for whatever application cache you have, e.g. `/root/.pnpm-store/v3` for pnpm, `$HOME/.m2` for maven, or `/root/.cache` for golang.
+
+### Customizing the run command
+
+By default no arguments are passed to `docker run` when deploying the container and the `CMD` or `ENTRYPOINT` defined in the `Dockerfile` are executed. You can take advantage of docker ability of overriding the `CMD` or passing parameters to your `ENTRYPOINT` setting `$DOKKU_DOCKERFILE_START_CMD`. Let's say for example you are deploying a base Node.js image, with the following `ENTRYPOINT`:
+
+```Dockerfile
+ENTRYPOINT ["node"]
+```
+
+You can do:
+
+```shell
+dokku config:set node-js-app DOKKU_DOCKERFILE_START_CMD="--harmony server.js"
+```
+
+To tell Docker what to run.
+
+Setting `$DOKKU_DOCKERFILE_CACHE_BUILD` to `true` or `false` will enable or disable Docker's image layer cache. Lastly, for more granular build control, you may also pass any `docker build` option to `docker`, by setting `$DOKKU_DOCKER_BUILD_OPTS`.
+
+### Procfiles and multiple processes
+
+> New as of 0.5.0
+
+You can also customize the run command using a `Procfile`, much like you would on Heroku or
+with a buildpack deployed app. The `Procfile` should contain one or more lines defining [process types and associated commands](https://devcenter.heroku.com/articles/procfile#declaring-process-types).
+When you deploy your app, a Docker image will be built. The `Procfile` will be extracted from the image
+(it must be in the folder defined in your `Dockerfile` as `WORKDIR` or `/app`) and the commands
+in it will be passed to `docker run` to start your process(es). Here's an example `Procfile`:
+
+```Procfile
+web: bin/run-prod.sh
+worker: bin/run-worker.sh
+```
+
+And `Dockerfile`:
+
+```Dockerfile
+FROM ubuntu:18.04
+WORKDIR /app
+COPY . ./
+CMD ["bin/run-dev.sh"]
+```
+
+When you deploy this app the `web` process will automatically be scaled to 1 and your Docker container
+will be started basically using the command `docker run bin/run-prod.sh`. If you want to also run
+a worker container for this app, you can run `dokku ps:scale worker=1` and a new container will be
+started by running `docker run bin/run-worker.sh` (the actual `docker run` commands are a bit more
+complex, but this is the basic idea). If you use an `ENTRYPOINT` in your `Dockerfile`, the lines
+in your `Procfile` will be passed as arguments to the `ENTRYPOINT` script instead of being executed.
+
+### Exposed ports
+
+See the [port management documentation](/docs/networking/port-management.md) for more information on how Dokku exposes ports for applications and how you can configure these for your app.

 ## Usage
 
+### Detection
+
+This builder will be auto-detected in either the following cases:
+
+- The `BUILDPACK_URL` app environment variable is set.
+  - 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.
+- A `.buildpacks` file exists in the root of the app repository.
+  - This can be via a committed `.buildpacks` file or managed via the `buildpacks` plugin commands.
+
+The builder can also be specified via the `builder:set` command:
+
+```shell
+dokku builder:set node-js-app selected herokuish
+```
+
+> Dokku will only select the `dockerfile` builder if both the `herokuish` and `pack` builders are not detected and a Dockerfile exists. See the [dockerfile builder documentation](/docs/deployment/builders/dockerfiles.md) for more information on how that builder functions.

+### Customizing the Buildpack stack builder
+
+> New as of 0.23.0
+
+The default stack builder in use by Herokuish buildpacks in Dokku is based on `gliderlabs/herokuish:latest`. Typically, this is installed via an OS package which pulls the requisite Docker image. Users may desire to switch the stack builder to a custom version, either to update the operating system or to customize packages included with the stack builder. This can be performed via the `buildpacks:set-property` command.
+
+```shell
+dokku buildpacks:set-property node-js-app stack gliderlabs/herokuish:latest
+```
+
+The specified stack builder can also be unset by omitting the name of the stack builder when calling `buildpacks:set-property`.
+
+```shell
+dokku buildpacks:set-property node-js-app stack
+```
+
+A change in the stack builder value will execute the `post-stack-set` trigger.
+
+Finally, stack builders can be set or unset globally as a fallback. This will take precedence over a globally set `DOKKU_IMAGE` environment variable (`gliderlabs/herokuish:latest-20` by default).

+```shell
+# set globally
+dokku buildpacks:set-property --global stack gliderlabs/herokuish:latest
