+description: Is your deploy failing while building your application using buildpacks? Check this out.
+labels: ["upstream: buildpacks"]
+body:
+  - type: markdown
+    attributes:
+      value: |
+        If your build is stuck downloading something, compiling a file, or seems to always fail around the same area, Github Issues is not a great place to debug. This is because these sorts of issues tend to take a lot of back and forth to figure out, and the code for buildpacks is not generally maintained by the Dokku project.
+
+        <details>
+        <summary>Debugging tips:</summary>
+
+        - If you see text that says `Killed` in your output, attempt to increase free memory by using a larger server or [add swap memory](https://dokku.com/docs/getting-started/troubleshooting/#build-fails-with-killed-message).
+        - Turn on buildpack trace mode via `dokku config:set $APP_NAME BUILDPACK_XTRACE=1` and retry your deploy. Not all buildpacks support this, but many will output extra debugging information.
+        - Your hosting provider may have issues accessing AWS S3. Verify a slow/stalled download works by directly curling the file from your host.
+        - Many buildpacks allow downloading a file from an alternative location specified via environment variable.
+        - [Increase curl timeouts](https://dokku.com/docs/getting-started/troubleshooting/#deployment-fails-because-of-slow-internet-connection-messages-s) if you see gzip download issues.
+        - If using multi-buildpack support but a buildpack is failing to apply, ensure you have any files necessary for the `bin/detect` script of the buildpack to `exit 0`. Selected buildpacks must still pass the detection phase in order to be used.
+        </details>
+
+        If you are still having issues, file a ticket here and then further discussing the ticket in one of our [Monitored Support Channels](https://dokku.com/docs/getting-started/where-to-get-help/#monitored-locations) (Discord, Github Discussions, Slack). Your filed ticket may be closed or locked, but any subsequent discovery will be posted to the ticket for posterity.

 ### Volumes and Static Assets
 
 Dokku doesn't enforce a [300mb](https://devcenter.heroku.com/articles/slug-compiler#slug-size) limit on apps, but it's best practice to keep binary assets outside of git. Since containers are considered volatile in Dokku, external stores like s3 or storage mounts should be used for non-volatile items like user uploads. The Dokku storage core plugin can be used to mount local directories / volumes inside the docker container.
 
 System administrators are highly encouraged to store persistent data in app-specific subdirectories of the path `/var/lib/dokku/data/storage`. This will help ensure restores of the aforementioned primary Dokku directories will restore service to all apps.

+## 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

+- `["/usr/bin/tini", "--"]`

-## `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.
+
+```shell
+dokku app-json:set --global appjson-path
+```
+
+### Displaying app-json reports for an app
+
+> New as of 0.25.0
+
+You can get a report about the app's storage status using the `app-json:report` command:
+

-- Using implicit paths that do not exist are no longer supported, and actually deprecated in [Docker 1.9.0](https://github.com/docker/docker/releases/tag/v1.9.0). When you specify a persistent storage mount, the host directory is **not** autocreated by either Dokku or Docker.
-- We recommend using the directory `/var/lib/dokku/data/storage` directory as the root host path for mounts, and we create this on Dokku installation.
-- Mounts are only available at run and deploy times, and you **must** redeploy (restart) an app to mount or unmount to an existing app's container.
-- When a directory is mounted, any existing files within the container will be overwritten. If you are writing assets during the build process and then replace the directory with a mount, those files will no longer exist. This is a Docker limitation.
-- Paths are mounted within the container at the root of the disk - `/` - and are **not** relative to `/app` (for buildpacks deploys) or the `WORKDIR` (for Dockerfile/Docker images).
-- For applications using buildpack deploys, the host directory should be owned by the user and group id `32767`. This is due to how permissions within Herokuish - which builds the Docker images - works. For Dockerfile or Docker image deployments, please use the user and group id which corresponds to the one running the process within the container.

 ## Usage
 
-This example demonstrates how to mount the recommended directory to `/storage` inside an application called `node-js-app`:
+### 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/node-js-app` 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/processes/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.
+
+```shell
+dokku ps:restart app-name
+```

+```
+
+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
+dokku registry:set node-js-app push-on-release
+
+# globally

-# Alternative Schedulers
-
-In addition to the built-in [docker-local scheduler](/docs/advanced-usage/schedulers/docker-local.md), Dokku also supports two scheduler plugins:
-
-- [Kubernetes](https://github.com/dokku/dokku-scheduler-kubernetes)
-- [Nomad](https://github.com/dokku/dokku-scheduler-nomad)
-
-These scheduler implementations may not be complete, though provide enough functionality for a user to get an app deployed via the underlying scheduler.
-
-For users that require additional functionality, please refer to the [Sponsoring Documentation](https://github.com/dokku/.github/blob/master/SPONSORING.md).

-
-```
-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-app-rename-setup`
-- `post-create`
-- `post-delete`
-- `pre-deploy`
-- `pre-restore`
-- `scheduler-app-status`

-- `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
-

+# 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.
+
+Before upgrading, uninstall the registry plugin via `dokku plugin:uninstall registry`. Not doing so will cause issues with Dokku.
+
+## 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.

 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.)

+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:
+

+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.

+# Lambda Builder
+
+> New as of 0.28.0
+
+The `lambda` builder builds AWS Lambda functions in an environment simulating AWS Lambda runtimes via [lambda-builder](https://github.com/dokku/lambda-builder). Apps built via this builder can run natively in Dokku and may also have their artifacts scheduled to Lambda via an appropriate scheduler.
+
+## Usage
+
+### Detection
+
+This builder will be auto-detected in the following case:
+
+- A `lambda.yml` exists in the root of the app repository.
+
+The builder may also be selected via the `builder:set` command
+
+```shell
+dokku builder:set node-js-app selected lambda
+```
+
+### Supported languages
+
+The `lambda` builder plugin supports the following AWS runtime languages on Amazon Linux 2:
+
+- dotnet
+- go (builder is based on AL1)
+- nodejs
+- python
+- ruby
+
+See the [lambda-builder](https://github.com/dokku/lambda-builder#how-does-it-work) documentation for more information on how specific languages are detected.
+
+### Customizing the build environment
+
+The `lambda` builder plugin delegates all build logic to [lambda-builder](https://github.com/dokku/lambda-builder), including language detection and build/runtime environment specification. The lambda-builder tool supports a `lambda.yml` file format for customizing how apps are built. Please see the readme for lambda-builder for more information on different options.
+
+### Changing the `lambda.yml` location
+
+When deploying a monorepo, it may be desirable to specify the specific path of the `lambda.yml` file to use for a given app. This can be done via the `builder-lambda: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-lambda:set node-js-app lambdayml-path lambda2.yml
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku builder-lambda:set node-js-app lambdayml-path
+```
+
+The `lambdayml-path` property can also be set globally. The global default is `lambda.yml`, and the global value is used when no app-specific value is set.
+
+```shell

+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell

-The Dokku tags plugin allows you to add Docker image tags to the currently deployed app image for versioning and subsequent deployment.
-
-> When triggering `dokku ps:rebuild APP` on an application deployed via the `tags` plugin, the following may occur:
->
-> - Applications previously deployed via another method (`git`/`tar`): The application may revert to a state before the latest custom image tag was deployed.
-> - Applications that were only ever deployed via the `tags` plugin: No action will be taken against your application.
->
-> Please use the `tags:deploy` command when redeploying an application deployed via Docker image.
-
-## Usage
-
-### 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.
-
-### Listing tags for an application
-
-For example, you can list all tags for a given application:
-
-```shell
-dokku tags node-js-app
-```
-
-```
-=====> Image tags for dokku/node-js-app
-REPOSITORY          TAG                 IMAGE ID            CREATED              VIRTUAL SIZE
-dokku/node-js-app   latest              936a42f25901        About a minute ago   1.025 GB
-```
-
-### Creating a tag
-
-You can also create new tags for that app using the `tags:create` function. Tags should conform to the Docker tagging specification for your Docker version. As of 1.10, that specification is available [here](https://github.com/docker/docker/blob/master/image/spec/v1.1.md), while users of older versions can check the documentation [here](https://github.com/docker/docker/blob/master/image/spec/v1.md).
-
-```shell
-dokku tags:create node-js-app v1
-```
-
-```
-=====> Added v1 tag to dokku/node-js-app
-```
-
-Once the tag is created, you can see the output by running the `tags` command again.
-
-```shell
-dokku tags node-js-app
-```
-
-```
-=====> Image tags for dokku/node-js-app
-REPOSITORY          TAG                 IMAGE ID            CREATED              VIRTUAL SIZE
-dokku/node-js-app   latest              936a42f25901        About a minute ago   1.025 GB
-dokku/node-js-app   v1                  936a42f25901        About a minute ago   1.025 GB
-```
-
-### Deploying an image tag
-
-Finally, you can also deploy a local image using the `tags:deploy` command. When specifying a tag that is not `latest`, the released image will be retagged as the `latest` image tag for the app.
-
-> Warning: For images based on Herokuish, using the `tags:deploy` command will reset environment variables written into the image, causing a retag to occur. This will - on average - add two extra layers to your deployed image. Note that this does not affect Dockerfile-based images, which are the majority of images deployed via the `tags` command.
-
-```shell
-dokku tags:deploy node-js-app v1

-
-## Image workflows
-
-### Deploying from a Docker registry
-
-You can alternatively add image pulled from a Docker registry and deploy from it by using tagging feature. In this example, we are deploying from Docker Hub.
-
-1. Create Dokku app as usual.
-
-    ```shell
-    dokku apps:create test-app
-    ```
-
-2. Pull image from Docker Hub.
-
-    ```shell
-    docker pull demo-repo/some-image:v12
-    ```
-
-3. Retag the image to match the created app.
-
-    ```shell
-    docker tag demo-repo/some-image:v12 dokku/test-app:v12
-    ```
-
-4. Deploy tag.
-
-    ```shell
-    dokku tags:deploy test-app v12
-    ```
-
-### Deploying an image from CI
-
-To ensure your builds are always reproducible, it's considered bad practice to store build
-artifacts in your repository. For some projects however, building artifacts during deployment
-to Dokku may affect the performance of running applications.
-
-One solution is to build a finished Docker image on a CI service (or even locally) and deploy
-it directly to the host running Dokku.
-
-1. Build image on CI (or locally).
-
-    ```shell
-    docker build -t dokku/test-app:v12 .
-    # Note: The image must be tagged `dokku/<app-name>:<version>`
-    ```
-
-2. Deploy image to Dokku host.
-
-    ```shell
-    docker save dokku/test-app:v12 | ssh my.dokku.host "docker load | dokku tags:deploy test-app v12"
-    ```
-
-> Note: You can also use a Docker registry to push and pull
-> the image rather than uploading it directly.
-
-Here's a more complete example using the above method:
-
-```shell
-# build the image
-docker build -t dokku/test-app:v12 .
-# copy the image to the dokku host
-docker save dokku/test-app:v12 | bzip2 | ssh my.dokku.host "bunzip2 | docker load"
-# tag and deploy the image
-ssh my.dokku.host "dokku tags:create test-app previous; dokku tags:deploy test-app v12"
-```

-
-### Deploying from a tarball
-
-In some cases, it may be useful to deploy an application from a tarball. For instance, if you implemented a non-Git based deployment plugin, tarring the generated artifact may be an easier route to interface with the existing Dokku infrastructure.
-
-You can place the tarball on an external webserver and deploy via the `tar:from` command.
-
-```shell
-dokku tar:from node-js-app https://dokku.me/releases/node-js-app/v1
-```
-
-### Deploying via stdin
-

+```
+
+> 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
+```
+
+### Disabling the init process
+
+The `scheduler-docker-local` injects an init process by default via the `--init`. For some apps - such as those where the built docker image uses S6 as the init - this may be undesirable and cause issues with process starts. 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 init-process false
+```
+
+Once set, you may re-enable it by setting a blank value for `init-process`:
+
+```shell
+dokku scheduler-docker-local:set node-js-app init-process
+```
+
+All image containers with the label `org.opencontainers.image.vendor=linuxserver.io` will have the automatic init process injection force-disabled without further intervention.
+
+### Deploying Process Types in Parallel
+
+> New as of 0.25.5
+
+By default, Dokku deploys an app's processes one-by-one in order, with the `web` process being deployed first. Deployment parallelism may be achieved by setting the `parallel-schedule-count` property, which defaults to `1`. Increasing this number increases the number of process types that may be deployed in parallel (with the web process being the exception).
+
+```shell
+# Increase parallelism from 1 process type at a time to 4 process types at a time.
+dokku scheduler-docker-local:set node-js-app parallel-schedule-count 4
+```
+
+Once set, you may reset it by setting a blank value for `parallel-schedule-count`:
+
+```shell
+dokku scheduler-docker-local:set node-js-app parallel-schedule-count
+```
+
+If the value of `parallel-schedule-count` is increased and a given process type fails to schedule successfully, then any in-flight process types will continue to be processed, while all process types that have not been scheduled will be skipped before the deployment finally fails.
+
+Container scheduling output is shown in the order it is received, and thus may be out of order in case of output to stderr.
+
+Note that increasing the value of `parallel-schedule-count` may significantly impact CPU utilization on your host as your app containers - and their respective processes - start up. Setting a value higher than the number of available CPUs is discouraged. It is recommended that users carefully set this value so as not to overburden their server.
+
+#### Increasing parallelism within a process deploy
+
+> New as of 0.26.0
+
+By default, Dokku will deploy one instance of a given process type at a time. This can be increased by customizing the `app.json` `formation` key to include a `max_parallel` key for the given process type.
+
+An `app.json` file can be committed to the root of the pushed app repository, and must be within the built image artifact in the image's working directory as shown below.
+
+- Buildpacks: `/app/app.json`
+- Dockerfile: `WORKDIR/app.json` or `/app.json` (if no working directory specified)
+- Docker Image: `WORKDIR/app.json` or `/app.json` (if no working directory specified)
+
+The `formation` key should be specified as follows in the `app.json` file:
+
+```Procfile
+{
+  "formation": {
+    "web": {
+      "max_parallel": 1
+    },
+    "worker": {
+      "max_parallel": 4
+    }
+  }
+}
+```
+
+Omitting or removing the entry will result in parallelism for that process type to return to 1 entry at a time. This can be combined with the  `parallel-schedule-count` property to speed up deployments.
+
+Note that increasing the value of `max_parallel` may significantly impact CPU utilization on your host as your app containers - and their respective processes - start up. Setting a value higher than the number of available CPUs is discouraged. It is recommended that users carefully set this value so as not to overburden their server.
+
+## Scheduler Interface
+
+The following sections describe implemented scheduler functionality for the `docker-local` scheduler.
+
+### Implemented Commands and 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.
+
+- `apps:clone`
+- `apps:destroy`
+- `apps:rename`
+- `deploy`
+- `enter`
+- `logs`
+- `ps:inspect`
+- `ps:stop`
+- `run`
+
+
+### Logging support
+
+App logs for the `logs` command are fetched from running containers via the `docker` cli. To persist logs across deployments, consider using Dokku's [vector integration](deployment/logs.md#vector-logging-shipping) to ship logs to another service or a third-party platform.
+
+### 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`), is specified in number of CPUs a process can access.
+  - See the ["CPU" section](https://docs.docker.com/config/containers/resource_constraints/#cpu) of the Docker Runtime Options documentation for more information.
+- memory: (docker option: `--memory`) should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes). Default unit is `m` (megabytes).
+  - See the ["Memory" section](https://docs.docker.com/config/containers/resource_constraints/#memory) of the Docker Runtime Options documentation for more information.
+- memory-swap: (docker option: `--memory-swap`) should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes)
+  - See the ["Memory" section](https://docs.docker.com/config/containers/resource_constraints/#memory) of the Docker Runtime Options documentation for more information.
+- nvidia-gpus: (docker option: `--gpus`), is specified in number of Nvidia GPUs a process can access.
+  - See the ["GPU" section](https://docs.docker.com/config/containers/resource_constraints/#gpu) of the Docker Runtime Options documentation for more information.
+
+#### Resource Reservations
+
+- memory: (docker option: `--memory-reservation`) should be specified with a suffix of `b` (bytes), `k` (kilobytes), `m` (megabytes), `g` (gigabytes). Default unit is `m` (megabytes).
+  - See the ["Memory" section](https://docs.docker.com/config/containers/resource_constraints/#memory) of the Docker Runtime Options documentation for more information.
