@@ -2758,8 +3339,8 @@ This release is a minor bugfix to fix an issue with ssl support for spdy-enabled
 
 The big-six-o. This release is largely comprised of new features that should allow for easier management of dokku. The highlights of this release are:
 
-- The proxy plugin has been enhanced to allow users to map container ports to host ports. In the 0.5.0 release, we changed the semantics of how Dockerfile `EXPOSE` calls work to better follow Docker's lead, which ended up breaking how some applications were deployed to dokku. Please read our documentation surrounding [port management](http://dokku.viewdocs.io/dokku/proxy/) for more details.

 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.

+## Usage
+
+### Overview
+
 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`)
+- 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` 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
+dokku app-json:set --global appjson-path global-app.json
+```
+
+The default value may be set by passing an empty value for the option.

 - `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.

 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`.

+registry:set <app> <key> (<value>)                                 # Set or clear a registry property for an app
+```
+
+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 imag 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
+dokku registry:set node-js-app push-on-release
+
+# globally
+dokku registry:set --global push-on-release

+## Changes
+
+- The commands `proxy:enable`, `proxy:disable` and `proxy:build-config` now support the `--all` flag in addition to general parallelism.
+- The `builder-cnb` plugin has been renamed `builder-pack`, and all related plugin triggers have had the suffix `-cnb` changed to `-pack`.
+
+## 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. It will be removed in the next minor release, and is considered unmaintained. Users are highly encouraged to switch their workflows to `git:from-image`.

+# 0.25.0 Migration Guide
+
+## 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.
+
+### 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 `formations` 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.

 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.)

 The domains plugin allows you to specify custom domains for applications. This plugin is aware of any ssl certificates that are imported via `certs:add`. Be aware that disabling domains (with `domains:disable`) will override any custom domains.

If your app uses a non-standard port (perhaps you have a dockerfile deploy exposing port `99999`) you may need to manually expose an ssl port via `dokku proxy:ports-add <APP> https:443:99999`.

+### Setting up SSL
+
+> While SSL certificates can be imported, automated SSL via Letsencrypt requires that all domains on an app correctly point at your server's public ip address. Please keep this in mind when using Letsencrypt.
+
+For many users, responding to requests via `https` will be desirable. Dokku has a complete [ssl plugin](/docs/configuration/ssl.md) built in that can be used to import SSL certificates (below is a short example, please refer to the [ssl documentation](/docs/configuration/ssl.md) for more information):
+
+```shell
+dokku certs:add ruby-getting-started server.crt server.key
+```
+
+As an alternative, the Dokku project offers an optional letsencrypt plugin that can be used to automate SSL certificate retrieval and renewal.
+
+```shell
+# on the Dokku host
+# install the letsencrypt plugin
+# plugin installation requires root, hence the user change
+sudo dokku plugin:install https://github.com/dokku/dokku-letsencrypt.git

+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-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
+dokku builder:report
+```
+
+```
+=====> node-js-app builder information
+       Builder build dir:          custom
+       Builder computed build dir: custom
+       Builder computed selected:  herokuish

+       Builder global selected: herokuish

+       Builder computed selected: herokuish
+       Builder global build dir:
+       Builder global selected: herokuish
+       Builder selected:
+```
+
+You can run the command for a specific app also.
+
+```shell
+dokku builder:report node-js-app
+```
+
+```
+=====> node-js-app builder information
+       Builder selected: herokuish
+```
+
+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.

+```
+
+```

+```
+
+### 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

+```
+
+### Displaying builder-dockerfile reports for an app

+```
+
+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 $NODE_ENV
+```
+
+### Building images with Docker Buildkit
+
+If your Dockerfile is using Docker engine's [buildkit](https://docs.docker.com/develop/develop-images/build_enhancements/) (not to be confused with buildpacks), then the `DOCKER_BUILDKIT=1` environment variable needs to be set. Additionally, complete build log output can be forced via `BUILDKIT_PROGRESS=plain`. Both of these environment variables can be set as follows:
+
+```shell
+# via config:set
+dokku config:set --global DOCKER_BUILDKIT=1 BUILDKIT_PROGRESS=plain
+
+# on the /etc/default/dokku file
+echo DOCKER_BUILDKIT=1 | sudo tee -a /etc/default/dokku
+echo BUILDKIT_PROGRESS=plain | sudo tee -a /etc/default/dokku
+```
+
+#### Buildkit directory caching
+
+Buildkit implements the `RUN --mount` option, enabling mount directory caches for `RUN` directives. The following is an example that mounts debian packaging related directories, which can speed up fetching of remote package data.
+
+```Dockerfile
+FROM debian:latest
+RUN --mount=target=/var/lib/apt/lists,type=cache \
+    --mount=target=/var/cache/apt,type=cache \
+    apt-get update \
+ && DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends \
+      git
+```
+
+Mount cache targets may vary depending on the tool in use, and users are encouraged to investigate the directories that apply for their language and framework.
+
+You would adjust the cache directory for whatever application cache you have, e.g. `/root/.pnpm-store/v3` for pnpm, `$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

-
-> 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/methods/herokuish.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
-
-To use this builder instead of either `Dockerfile` or `herokuish`, you must set the `DOKKU_CNB_EXPERIMENTAL` environment variable for your app to `1`.
-
-```shell
-dokku config:set --no-restart node-js-app DOKKU_CNB_EXPERIMENTAL=1
-```
-
-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.

-
-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

-# 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.
-
-To use a Dockerfile for deployment, commit a valid `Dockerfile` to the root of your repository and push the repository to your Dokku installation. If this file is detected, Dokku will default to using it to construct containers *except* in the following two cases:
-
-- The application has a `BUILDPACK_URL` environment variable set via the `dokku config:set` command or in a committed `.env` file. In this case, Dokku will use your specified buildpack.
-- The application has a `.buildpacks` file in the root of the repository. In this case, Dokku will use your specified buildpack(s).
-
-## 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 
-```
-
-## 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'
-```
-
-The location of the `Dockerfile` may also be specified. If the location is changed, the repository **must also** have a `Dockerfile` in the root directory in order to trigger a dockerfile-based deploy.
-
-```shell
-dokku docker-options:add node-js-app build '--file Dockerfile.dokku'
-```
-
-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 $NODE_ENV
-```
-
-## Building images with Docker Buildkit
-
-If your Dockerfile is using Docker engine's [buildkit](https://docs.docker.com/develop/develop-images/build_enhancements/) (not to be confused with buildpacks), then the `DOCKER_BUILDKIT=1` environment variable needs to be set. One way to do this is to edit `/etc/environment` on your dokku host and reboot your instance. Note, for complete build log output, you should also set `BUILDKIT_PROGRESS=plain` in the same file. 
-
-## Customizing the run command
-
-By default no arguments are passed to `docker run` when deploying the container and the `CMD` or `ENTRYPOINT` defined in the `Dockerfile` are executed. You can take advantage of docker ability of overriding the `CMD` or passing parameters to your `ENTRYPOINT` setting `$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

 ### Initializing an application
 
 When an application is created via `git push`, Dokku will create the proper `pre-receive` hook in order to execute the build pipeline. In certain cases - such as when fronting deploys with the [`git-http-backend`](https://git-scm.com/docs/git-http-backend) - this may not be correctly created. As an alternative, the `git:initialize` command can be used to trigger this creation:

+
+### Initializing an app repository from a docker image
+
+> New as of 0.24.0
+
+A Dokku app repository can be initialized or updated from a Docker image via the `git:from-image` command. This command will either initialize the app repository or update it to include the specified Docker image via a `FROM` stanza. This is an excellent way of tracking changes when deploying only a given docker image, especially if deploying an image from a remote CI/CD pipeline.
+
+```shell
+dokku git:from-image node-js-app dokku/node-js-getting-started:latest
+```
+
+In the above example, Dokku will build the app as if the repository contained _only_ a `Dockerfile` with the following content:
+
+```Dockerfile
+FROM dokku/node-js-getting-started:latest
+```
+
+Triggering a build with the same arguments multiple times will result in Dokku exiting `0` early as there will be no changes detected.
+
+The `git:from-image` command can optionally take a git `user.name` and `user.email` argument (in that order) to customize the author. If the arguments are left empty, they will fallback to `Dokku` and `automated@dokku.sh`, respectively.
+
+```shell
+dokku git:from-image node-js-app dokku/node-js-getting-started:latest "Camila" "camila@example.com"
+```
+
+Finally, certain images may require a custom build context in order for `ONBUILD ADD` and `ONBUILD COPY` statements to succeed. A custom build context can be specified via the `--build-dir` flag. All files in the specified `build-dir` will be copied into the repository for use within the `docker build` process. The build context _must_ be specified on each deploy, and is not otherwise persisted between builds.
+
+```shell
+dokku git:from-image --build-dir path/to/build node-js-app dokku/node-js-getting-started:latest "Camila" "camila@example.com"
+```
+
+See the [dockerfile documentation](/docs/deployment/builders/dockerfiles.md) to learn about the different ways to configure Dockerfile-based deploys.
+
+### Initializing an app repository from an archive file
+
+> New as of 0.24.0
+
+A Dokku app repository can be initialized or updated from the contents of an archive file via the `git:from-archive` command. This is an excellent way of tracking changes when deploying pre-built binary archives, such as java jars or go binaries. This can also be useful when deploying directly from a GitHub repository at a specific commit.
+
+```shell
+dokku git:from-archive node-js-app https://github.com/dokku/smoke-test-app/releases/download/2.0.0/smoke-test-app.tar
+```
+
+In the above example, Dokku will build the app as if the repository contained the extracted contents of the specified archive file.
+
+Triggering a build with the same archive file multiple times will result in Dokku exiting `0` early as there will be no changes detected.
+
+The `git:from-archive` command can optionally take a git `user.name` and `user.email` argument (in that order) to customize the author. If the arguments are left empty, they will fallback to `Dokku` and `automated@dokku.sh`, respectively.

+dokku git:from-archive node-js-app https://github.com/dokku/smoke-test-app/releases/download/2.0.0/smoke-test-app.tar "Camila" "camila@example.com"
+```
+
+The default archive type is always set to `.tar`. To use a different archive type, specify the `--archive-type` flag. Failure to do so will result in a failure to extract the archive.
+
+```shell
+dokku git:from-archive --archive-type zip node-js-app https://github.com/dokku/smoke-test-app/archive/2.0.0.zip "Camila" "camila@example.com"

+### Initializing from private repositories
+
+> New as of 0.24.0
+
+Initializing from a private repository requires one of the following:
+
+- A Public SSH Key (`id_rsa.pub` file) configured on the remote server, with the associated private key (`id_rsa`) in the Dokku server's `/home/dokku/.ssh/` directory.
+- A configured [`.netrc`](https://www.gnu.org/software/inetutils/manual/html_node/The-_002enetrc-file.html) entry.
+
+Dokku provides the `git:auth` command which can be used to configure a `netrc` entry for the remote server. This command can be used to add or remove configuration for any remote server.
+
+```shell
+# add credentials for github.com
+dokku git:auth github.com username personal-access-token
+
+# remove credentials for github.com
+dokku git:auth github.com
+```
+
+For syncing to a private repository stored on a remote Git product such as GitHub or GitLab, Dokku's recommendation is to use a personal access token on a bot user where possible. Please see your service's documentation for information regarding the recommended best practices.

 To update the package clone the repository and adjust the files in the repository. Then a helper script - `updpkgsums` - to update the SHA sum could  be called (check against the original SHA sum). Another helper script - `mksrcinfo` - needs to be called to update the meta information of the package in a file called `.SRCINFO`. The next step builds the package locally for verification - `makepkg`. As last step commit your changes and push the commit.

+## Pushing Applications
+
+When exposing the Dokku container's SSH port (22) on 3022, something similar to the following will need to be setup within the user's `~/.ssh/config`:
+
+```
+Host dokku.docker
+  HostName 127.0.0.1
+  Port 3022
+```
+
+In the above example, the hostname `127.0.0.1` is being aliased to `dokku.docker`, while the port is being overriden to `3022`. All SSH commands - including git pushes - for the hostname `dokku.docker` will be transparently sent to `127.0.0.1:3022`.

+#### 2. Optionally connect a domain to your server
 
-Once the installation is complete, you can open a browser to setup your SSH key and virtualhost settings. Open your browser of choice and navigate to the host's IP address - or the domain you assigned to that IP previously - and configure Dokku via the web admin.
+Dokku optionally supports one or more domain names. If you do not own a domain name, you may either purchase one or skip this step.
 
-Alternatively, instructions to skip the web installer with an unattended installation are available in the [advanced install guide](/docs/getting-started/advanced-installation/#configuring). 
+When connecting a domain, either a single domain or a wildcard may be associated to the server's IP.

Please see the [dns documentation](/docs/networking/dns.md) and [domains documentation](/docs/configuration/domains.md) for more details.
 
-> **Warning:** If you don't complete setup via the web installer (even if you set up SSH keys and virtual hosts otherwise) your Dokku installation will remain vulnerable to anyone finding the setup page and inserting their key.

 The `remote rejected` error does not give enough information. Anything could have failed. Enable trace mode and begin debugging. If this does not help you, create a [gist](https://gist.github.com) containing the full log, and create an issue.
 
 One the reasons why you may get this error is because the command that is run in the container exited (without errors). For example, (in Procfile) when you define a new worker container to run Delayed Job and use the bin/delayed_job start command. This command deamonizes the process and exists. The container thinks it's done so it closes itself. The error you get is the one above. To fix the above problem for Delayed Job, you must define the worker to user rake jobs:work, which doesn't deamonize the process.

 This isn't usually an issue with Dokku, but rather an app config problem. This can happen when your application is configured to enforce secure connections/HSTS, but you don't have SSL set up for the app.
 
 In Rails at least, if your `application.rb` or `environmnents/production.rb` include the line `configure.force_ssl = true` which includes HSTS, try commenting that out and redeploying.
 
-If this solves the issue temporarily, longer term you should consider [configuring SSL](http://dokku.viewdocs.io/dokku/configuration/ssl/).
