+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.

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-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,
-nationality, personal appearance, race, religion, or sexual identity and
-orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
-advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
-  address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions

-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at dokku@josediazgonzalez.com. All
-complaints will be reviewed and investigated and will result in a response that

+
+## Requirements
+
+A fresh VM running any of the following operating systems:
+
+- Ubuntu 18.04 / 20.04 / 22.04 x64 - Any currently supported release
+- Debian 10+ x64
+- Arch Linux x64 *(experimental)*
+
+An SSH keypair that can be used for application deployment. If this exists before installation, it will be automatically imported into dokku.
+Otherwise, you will need to import the keypair manually after installation using `dokku ssh-keys:add`.
+
+## Installation
+
+To install the latest stable release, run the following commands as a user who has access to `sudo`:
+
+```shell
+wget https://raw.githubusercontent.com/dokku/dokku/v0.28.0/bootstrap.sh
+sudo DOKKU_TAG=v0.28.0 bash bootstrap.sh
+```
+
+You can then proceed to configure your server domain (via `dokku domains:set-global`) and user access (via `dokku ssh-keys:add`) to complete the installation.
+
+If you wish for a more unattended installation method, see [these](https://dokku.com/docs/getting-started/install/debian/#unattended-installation) docs.
+
+### Upgrade

-# Advanced installation
-
-You can always install dokku straight from the latest - potentially unstable - master release via the following bash command:
-
-```shell
-# using a branch results in installing from source
-wget https://raw.githubusercontent.com/dokku/dokku/master/bootstrap.sh
-sudo DOKKU_BRANCH=master bash bootstrap.sh
-```
-
-## Development
-
-If you plan on developing dokku, the easiest way to install from your own repository is cloning the repository and calling the install script. Example:
-
-```shell
-git clone https://github.com/yourusername/dokku.git
-cd dokku
-sudo make install
-```
-
-The `Makefile` allows source URLs to be overridden to include customizations from your own repositories. The `DOCKER_URL`, `PLUGN_URL`, `SSHCOMMAND_URL` and `STACK_URL` environment variables may be set to override the defaults (see the `Makefile` for how these apply). Example:
-
-```shell
-sudo SSHCOMMAND_URL=https://raw.githubusercontent.com/yourusername/sshcommand/master/sshcommand make install
-```
-
-## Bootstrap a server from your own repository
-
-The bootstrap script allows the dokku repository URL to be overridden to bootstrap a host from your own clone of dokku using the `DOKKU_REPO` environment variable. Example:
-
-```shell
-wget https://raw.githubusercontent.com/dokku/dokku/master/bootstrap.sh
-chmod +x bootstrap.sh
-sudo DOKKU_REPO=https://github.com/yourusername/dokku.git DOKKU_BRANCH=master ./bootstrap.sh
-```
-
-## Custom herokuish build
-
-Dokku ships with a pre-built version of version of the [herokuish](https://github.com/gliderlabs/herokuish) component by default. If you want to build your own version you can specify that with an env variable.
-
-```shell
-git clone https://github.com/dokku/dokku.git
-cd dokku
-sudo BUILD_STACK=true STACK_URL=https://github.com/gliderlabs/herokuish.git make install
-```
-
-## Configuring
-
-Once dokku is installed, if you are not using the web-installer, you'll want to configure a the virtualhost setup as well as the push user. If you do not, your installation will be considered incomplete and you will not be able to deploy applications.
-
-*You should also stop and disable the `dokku-installer` service to remove public access to adding SSH keys.*
-
-Set up a domain and a wildcard domain pointing to that host. Make sure `/home/dokku/VHOST` is set to this domain. By default it's set to whatever hostname the host has. This file is only created if the hostname can be resolved by dig (`dig +short $(hostname -f)`). Otherwise you have to create the file manually and set it to your preferred domain. If this file still is not present when you push your app, dokku will publish the app with a port number (i.e. `http://example.com:49154` - note the missing subdomain).
-
-Follow the [user management documentation](/dokku/deployment/user-management) in order to add users to dokku.
-
-That's it!
-
-## VMs with less than 1GB of memory
-
-Having less than 1GB of system memory available for dokku and its containers, for example Digital Ocean's small 512MB machines, might result in unexpected errors, such as **! [remote rejected] master -> master (pre-receive hook declined)** during installation of NPM dependencies (https://github.com/npm/npm/issues/3867).
-
-To work around this issue, it might suffice to augment the linux swap file size to a maximum of twice the physical memory size.
-
-To resize the swap file of a 512MB machine to 1GB, follow these steps while in SSH within your machine:
-
-```shell
-cd /var
-touch swap.img
-chmod 600 swap.img
-
-dd if=/dev/zero of=/var/swap.img bs=1024k count=1000
-mkswap /var/swap.img
-swapon /var/swap.img
-free
-
-echo "/var/swap.img    none    swap    sw    0    0" >> /etc/fstab
-```

+# Backup and Recovery
+
+> The backup plugin was deprecated in 0.4.x, below are backup recommendations for 0.5.x and later.
+
+The best plan for disaster recovery is to always keep multiple (remote) copies of your local repo, static assets and periodic database dumps. Backups should be regularly tested for data integrity and completeness.
+
+## 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.
+
+```shell
+git remote rm dokku
+git remote add dokku dokku@[dokku.me:dokku.me]
+git push dokku [master]
+```
+
+### Docker Networks
+
+Docker networks generated by Dokku should be recreated. Running `dokku network:report` will output all networks in use by various apps, which can then be used to recreate them via `dokku network:create $NETWORK`.
+
+Networks created by tools other than Dokku may be created as they initially were.
+
+### Docker Image and Tar-based Apps
+
+These apps may fail to rebuild via the normal `ps:rebuild` method. Redeploy these apps by running the original commands used to deploy them
+
+### Datastores
+
+> Please note that point-in-time backups of the `/var/lib/dokku/services` directory may contain partially written data due to how various datastores work. Consult the official datastore documentation for the best documentation surrounding proper backup and restore procedures.
+
+Some plugins, like the official [dokku-postgres](https://github.com/dokku/dokku-postgres) plugin, have built-in commands that allow non-volatile data be exported and imported.
+
+For [dokku-postgres](https://github.com/dokku/dokku-postgres), use:
+
+```shell
+dokku postgres:export [db_name] > [db_name].dump
+dokku postgres:import [db_name] < [db_name].dump
+```
+
+Additionally, data for official datastores is located in the `/var/lib/dokku/services` directory. If the directory is restored and the plugin is available, a `dokku $SERVICE:start` may be enough to restart the service with the underlying data, so long as the datastore version does not change and the underlying data is not corrupt. If this is the case, it may be necessary to re-import all the data onto a fresh version of the datastore service.
+
+### Plugins
+
+The plugin directory is contained at the `/var/lib/dokku/plugins` directory. Core plugins will automatically be included in new installs, but custom plugins may not. The aforementioned `tar` creation command will back all plugins up, and the `tar` extract command will restore the plugins.
+
+Note that restoring a plugin will not trigger any `install` or `dependencies` triggers. You will need to run these manually. See the [plugin management documentation](/docs/advanced-usage/plugin-management.md#installing-a-plugin) for more information on how to trigger these two hooks.
+
+### Volumes and Static Assets
+
+Dokku doesn't enforce a [300mb](https://devcenter.heroku.com/articles/slug-compiler#slug-size) limit on apps, but it's best practice to keep binary assets outside of git. Since containers are considered volatile in Dokku, external stores like s3 or storage mounts should be used for non-volatile items like user uploads. The Dokku storage core plugin can be used to mount local directories / volumes inside the docker container.
+
+System administrators are highly encouraged to store persistent data in app-specific subdirectories of the path `/var/lib/dokku/data/storage`. This will help ensure restores of the aforementioned primary Dokku directories will restore service to all apps.
+
+See the [persistent storage documentation](/docs/advanced-usage/persistent-storage.md) for more information on how to attach persistent storage to your app.
+
+## Recovering app code
+
+In case of an emergency when your git repo and backups are completely lost, you can recover the last pushed copy from your remote Dokku server (assuming you still have the ssh key).
+
+```shell
+mkdir [app-name] ; cd !$
+git init && git remote add dokku dokku@[dokku.me:app-name]
+git pull dokku/master && git checkout dokku/master
+```

+# Deployment Tasks
+
+> New as of 0.5.0
+
+## 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`)
+
+To support this, Dokku provides support for a special `release` command within your app's `Procfile`, as well as a special `scripts.dokku` key inside of your app's `app.json` file. Be aware that all commands are run within the context of the built docker image - no commands affect the host unless there are volume mounts attached to your app.
+
+Each "phase" has different expectations and limitations:
+
+- `app.json`: `scripts.dokku.predeploy`
+  - When to use: This should be used if your app does not support arbitrary build commands and you need to make changes to the built image.
+  - Are changes committed to the image at this phase: Yes
+  - Example use-cases
+    - Bundling assets in a slightly different way
+    - Installing a custom package from source or copying a binary into place
+- `app.json`: `scripts.dokku.postdeploy`
+  - When to use: This should be used in conjunction with external systems to signal the completion of your deploy.
+  - Are changes committed to the image at this phase: No
+  - Example use-cases
+    - Notifying slack that your app is deployed
+    - Coordinating traffic routing with a central load balancer
+- `app.json`: `scripts.postdeploy`
+  - When to use: This should be used when you wish to run a command _once_, after the app is created and not on subsequent deploys to the app.
+  - Are changes committed to the image at this phase: No
+  - Example use-cases
+    - Setting up OAuth clients and DNS
+    - Loading seed/test data into the app’s test database
+- `Procfile`: `release`
+  - When to use: This should be used in conjunction with external systems to signal the completion of your app image build.
+  - Are changes committed to the image at this phase: No
+  - Example use-cases
+    - Sending CSS, JS, and other assets from your app’s slug to a CDN or S3 bucket
+    - Priming or invalidating cache stores
+    - Running database migrations
+
+Additionally, if using a Dockerfile with an `ENTRYPOINT`, the deployment task is passed to that entrypoint as is. The exceptions are if the entrypoint is one of the following:

+
+### 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

+
+### Deployment tasks
+
+#### `app.json` deployment tasks
+
+Dokku provides limited support for the `app.json` manifest from Heroku (documentation available [here](https://devcenter.heroku.com/articles/app-json-schema)). The keys available for use with Deployment Tasks are:
+
+- `scripts.dokku.predeploy`: This is run _after_ an app's docker image is built, but _before_ any containers are scheduled. Changes made to your image are committed at this phase.
+- `scripts.dokku.postdeploy`: This is run _after_ an app's containers are scheduled. Changes made to your image are _not_ committed at this phase.
+- `scripts.postdeploy`: This is run _after_ an app's containers are scheduled. Changes made to your image are _not_ committed at this phase.
+
+For buildpack-based deployments, the location of the `app.json` file should be at the root of your repository. Dockerfile-based app deploys should have the `app.json` in the configured `WORKDIR` directory; otherwise Dokku defaults to the buildpack app behavior of looking in `/app`.
+
+> Warning: Any failed `app.json` deployment task will fail the deploy. In the case of either phase, a failure will not affect any running containers.
+
+The following is an example `app.json` file. Please note that only the `scripts.dokku.predeploy` and `scripts.dokku.postdeploy` tasks are supported by Dokku at this time. All other fields will be ignored and can be omitted.
+
+```json
+{
+  "scripts": {
+    "dokku": {
+      "predeploy": "touch /app/predeploy.test",
+      "postdeploy": "curl https://some.external.api.service.com/deployment?state=success"
+    },
+    "postdeploy": "curl https://some.external.api.service.com/created?state=success"
+  }
+}
+```
+
+#### Procfile Release command
+
+> New as of 0.14.0
+
+The `Procfile` also supports a special `release` command which acts in a similar way to the [Heroku Release Phase](https://devcenter.heroku.com/articles/release-phase). This command is executed _after_ an app's docker image is built, but _before_ any containers are scheduled. This is also run _after_ any command executed by `scripts.dokku.predeploy`.
+
+To use the `release` command, simply add a `release` stanza to your Procfile.
+
+```Procfile
+release: curl https://some.external.api.service.com/deployment?state=built
+```
+
+Unlike the `scripts.dokku.predeploy` command, changes made during by the `release` command are _not_ persisted to disk.
+
+> Warning: scaling the release command up will likely result in unspecified issues within your deployment, and is highly discouraged.

+>
+> ```shell
+> dokku docker-options:add node-js-app deploy,run "-v /var/log/node-js-app:/app/logs"
+> ```
+
+## About Dokku phases
+
+Dokku deploys your application in multiple "phases" and the `docker-options` plugin allows you to pass arguments to their underlying docker container:
+
+- `build`: the container that executes the appropriate buildpack
+- `deploy`: the container that executes your running/deployed application
+- `run`: the container that executes any arbitrary command via `dokku run`
+
+Manipulation of docker options will not restart running containers. This enables multiple options to be set/unset before final application. As such, changing an app's docker options must be followed by a `dokku ps:rebuild` in order to take effect.
+
+More information on supported Docker options can be found here: https://docs.docker.com/engine/reference/commandline/run/.
+
+Container options configured via the `docker-options` plugin are not used to modify the process a container runs. Container options are the `[OPTIONS]` portion of the following, where `[CONTAINER_COMMAND]` and `[ARG]` are the process and the arguments passed to it that are launched in the created container: `docker run [OPTIONS] [CONTAINER_COMMAND] [ARG...]`. Please see the documentation for [customizing the run command](/docs/deployment/builders/dockerfiles.md#customizing-the-run-command) or use a [Procfile](/docs/deployment/builders/dockerfiles.md#procfiles-and-multiple-processes) to modify the command used by a Dockerfile-based container.
+
+## Examples
+
+### Add Docker options
+
+Add some options for the deployed/running app and when executing [`dokku run`](/docs/processes/one-off-tasks.md):
+
+```shell
+# Mount a host volume in a Docker container: "-v /host/path:/container/path"
+dokku docker-options:add node-js-app deploy "-v /var/log/node-js-app:/app/logs"
+dokku docker-options:add node-js-app run "-v /var/log/node-js-app:/app/logs"
+```
+
+> Note: When [mounting a host directory](https://docs.docker.com/engine/reference/run/#volume-shared-filesystems) in a Dokku app you should first create that directory as user `dokku` and then mount the directory under `/app` in the container using `docker-options` as above. Otherwise the app will lack write permission in the directory.
+
+### Remove a Docker option
+
+```shell
+dokku docker-options:remove node-js-app run "-v /var/log/node-js-app:/app/logs"
+```
+
+### Clear all Docker options for an app
+
+Docker options can be removed for a specific app using the `docker-options:clear` command.
+
+```shell
+dokku docker-options:clear node-js-app
+```
+
+```
+-----> Clearing docker-options for node-js-app on all phases
+```

+# Persistent Storage
+
+> New as of 0.5.0
+
+The preferred method to mount external containers to a Dokku managed container, is to use the Dokku storage plugin.
+
+```
+storage:ensure-directory [--chown option] <directory>  # Creates a persistent storage directory in the recommended storage path
+storage:list <app>                                     # List bind mounts for app's container(s) (host:container)
+storage:mount <app> <host-dir:container-dir>           # Create a new bind mount
+storage:report [<app>] [<flag>]                        # Displays a checks report for one or more apps
+storage:unmount <app> <host-dir:container-dir>         # Remove an existing bind mount
+```
+
+> The storage plugin is compatible with storage mounts created with the docker-options. The storage plugin will only list mounts from the deploy/run phase.
+
+The storage plugin supports the following mount points:
+
+- explicit paths that exist on the host
+- docker volumes
+
+## Usage
+
+### 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
+dokku storage:ensure-directory lollipop
+```
+
+```
+-----> Ensuring /var/lib/dokku/data/storage/lollipop exists
+       Setting directory ownership to 32767:32767
+       Directory ready for mounting
+```
+
+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
+```
+
+### 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
+# 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
+
+# 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
+```
+
+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
+```

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

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

+```
+
+The 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
+dokku registry:set --global push-on-release

+```
+
+The resource plugin is meant to allow users to limit or reserve resources for a given app/process-type combination.
+
+## Usage
+
+By default, Dokku allows unlimited resource access to apps deployed on a server. In some cases, it may be desirable to limit this on a per-app or per-process-type basis. The `resource` plugin allows management of both resource "limits" and resource "reservations", where each resource request type has specific meaning to the scheduler in use for a given app.
+
+> Warning: The meaning of a values and it's units are specific to the scheduler in use for a given app. If a value is incorrect for a scheduler, this may result in containers failing to start correctly. If a scheduler does not support a given resource type combination, it will be ignored. All resource commands require an app rebuild or deploy in order to take effect.
+
+Valid resource options include:
+
+- `--cpu`
+- `--memory`
+- `--memory-swap`
+- `--network`
+- `--network-ingress`
+- `--network-egress`
+- `--nvidia-gpu`
+
+See the [Supported Resource Management Properties](/docs/advanced-usage/schedulers/docker-local.md#supported-resource-management-properties) section of the docker local scheduler documentation for more information on how each resource limit maps to Docker.
+
+Resource limits and reservations are applied only during the `run` and `deploy` phases of an application, and will not impact the `build` phase of an application.
+
+### Resource Limits
+
+When specified and supported, a resource limit will ensure that your app does not go _over_ the specified value. If this occurs, the underlying scheduler may either cap resource utilization, or it may decide to terminate and reschedule your process.
+
+Resource limits may be set via the `resource:limit` command:
+
+```shell
+dokku resource:limit --memory 100 node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app
+       memory: 100
+```
+

+```
+
+```
+=====> Setting resource limits for node-js-app
+       cpu: 100
+       memory: 100
+```
+
+Resources can also be limited on a per-process type basis. If specified, this will override any generic limits set for the app.
+
+```shell
+dokku resource:limit --cpu 100 --memory 100 --process-type worker node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app (worker)
+       cpu: 100
+       memory: 100
+```
+
+A resource value can be individually cleared by setting the value to the special value `clear`.
+
+```shell
+dokku resource:limit --cpu clear node-js-app
+```
+
+```
+=====> Setting resource limits for node-js-app
+       cpu: cleared

+
+#### Displaying Resource Limits
+
+Running the `resource:limit` command without any flags will display the currently configured default app limits.
+
+```shell
+dokku resource:limit node-js-app
+```
+
+```
+=====> resource limits node-js-app information [defaults]

+       network-ingress:
+       network-egress:
+       nvidia-gpu:
+```
+
+This may also be combined with the `--process-type` flag to see app limits on a process-type level. Note that the displayed values are not merged with the defaults.
+
+```shell

+       network-egress:
+       nvidia-gpu:
+```
+
+#### Clearing Resource Limits
+
+In cases where the values are incorrect - or there is no desire to limit resources - resource limits may be cleared using the `resource:limit-clear` command.
+
+```shell
+dokku resource:limit-clear node-js-app
+```
+
+```
+-----> Clearing resource limit for node-js-app

+
+### Resource Reservations
+
+When specified and supported, a resource reservation will ensure that your server has _at least_ the specified resources before placing a given app's process. If there a resource exhaustion, future rebuilds and deploys may fail.
+
+Resource reservations may be set via the `resource:reserve` command:
+
+```shell
+dokku resource:reserve --memory 100 node-js-app
+```

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

+# 0.20.0 Migration Guide
+
+## Removals
+
+### Command removals
+
+The following commands were previously deprecated and were removed in this release.
+
+- `apps`: Use `apps:list` instead.
+- `certs`: Use `certs:report` instead.
+- `certs:info`: Use `certs:report` instead.
+- `checks`: Use `checks:report` instead.
+- `docker-options`: Use `docker-options:report` instead.
+- `domains`: Use `domains:report` instead.
+- `plugin`: Use `plugin:list` instead.
+- `proxy`: Use `proxy:report` instead.
+- `trace`: Use `trace:on` or `trace:off` instead.
+- `ps`: Use `enter` with a container ID instead to run `ps auxww` within a container.
+
+The refactor of the proxy plugin removes the following functions from being sourced in plugins:
+
+- `proxy#get_app_proxy_port_map()`
+- `proxy#list_app_proxy_ports()`
+- `proxy#filter_app_proxy_ports()`
+- `proxy#add_proxy_ports()`
+- `proxy#remove_proxy_ports()`
+- `proxy#set_proxy_ports()`
+
+The informal policy is to allow removal of functions within a `functions` file if they are not used in OSS plugins. Should you be affected by any such removals, please file an issue to expose the functionality via a plugin trigger.
+
+### Function renames
+
+- `tar#tar_in_cmd` was renamed to `tar#cmd-tar-in`. Users should avoid using `cmd-*` commands directly, and instead file an issue to have them exposed via a plugin trigger.
+- `tar#tar_from_cmd` was renamed to `tar#cmd-tar-from`. Users should avoid using `cmd-*` commands directly, and instead file an issue to have them exposed via a plugin trigger.
+
+### Remove support for Unsupported Operating Systems
+
+Dokku will no longer distribute packages for Ubuntu versions that have reached either End of Life or End of Standard Support (for LTS releases). This currently includes the following releases:
+
+- Ubuntu 14.04 (trusty)
+- Ubuntu 14.10 (utopic)
+- Ubuntu 15.04 (vivid)
+- Ubuntu 15.10 (wily)
+- Ubuntu 16.10 (yakkety)
+- Ubuntu 17.04 (zesty)
+- Ubuntu 17.10 (artful)
+
+Dokku will no longer distribute packages for Debian versions that are not `stable` or `oldstable`. This currently includes the following releases:
+
+- Debian 7 (wheezy)
+- Debian 8 (jessie)
+
+### 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. 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`.

+## 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.

+# 0.8.0 Migration Guide
+
+## Domain Management
+
+You can now set global and app domains via `domains:set` and `domains:set-global`. See the [domains documentation](/docs/configuration/domains/) for more details.
+
+## Plugin Uninstallation
+
+A new `uninstall` plugin trigger was introduced. This functionality may be in use for newer plugins, so be aware that older Dokku versions may require manual cleanup.
+
+See the [uninstall trigger documentation](/docs/development/plugin-triggers/#uninstall) for implementation instructions.
+
+## Deployment Tasks
+
+Should a pre or post deployment task fail, we now fail the entire deploy.
+
+## Nginx HTTP2 Support
+
+Due to bugs in Nginx, the minimum version for HTTP2 is now 1.11.5.

+# 0.9.0 Migration Guide
+
+## Golang Migration
+
+There is an ongoing migration to rewrite Dokku in Golang. The reasons are beyond the scope of this document, but this may impact any patches you have for Dokku. As of 0.9.0, only the `repo` plugin is in Golang.
+
+The following shall remain true, regardless of the state of our rewrite:
+
+- You will be able to write custom plugins in any language.
+- You will be able to enable or disable core plugins.
+- `plugn` will continue to be used for executing plugin triggers.
+- We will provide bash wrappers that can be sourced to execute core functionality that is implemented in golang.

-# Deploying to Dokku
-
-## Deploy tutorial
-
-Once Dokku has been configured with at least one user, applications can be deployed via a `git push` command. To quickly see Dokku deployment in action, you can use the Heroku Ruby on Rails example app.
-
-```shell
-# from your local machine
-git clone git@github.com:heroku/ruby-rails-sample.git
-```
-
-### Create the app
-
-Create the application on the Dokku host. You will need to ssh onto the host to run this command.
-
-```shell
-# on your dokku host
-dokku apps:create ruby-rails-sample
-```
-
-### Create the backing services
-
-When you create a new app, Dokku by default *does not* provide any datastores such as MySQL or PostgreSQL. You will need to install plugins to handle that, but fortunately [Dokku has official plugins](/dokku/plugins/#official-plugins-beta) for common datastores. Our sample app requires a PostgreSQL service:
-
-```shell
-# on your dokku host
-# install the postgres plugin
-# plugin installation requires root, hence the user change
-sudo dokku plugin:install https://github.com/dokku/dokku-postgres.git
-
-# create a postgres service with the name rails-database
-dokku postgres:create rails-database
-```
-
-> Each services may take a few moments to create.
-
-### Linking backing services to applications
-
-Once the service creation is complete, set the `POSTGRES_URL` environment variable by linking the service.
-
-```shell
-# on your dokku host
-# each official datastore offers a `link` method to link a service to any application
-dokku postgres:link rails-database ruby-rails-sample
-```
-
-> You can link a single service to multiple applications or use one service per application.
-
-### Deploy the app
-
-Now you can deploy the `ruby-rails-sample` app to your Dokku server. All you have to do is add a remote to name the app. Applications are created on-the-fly on the Dokku server.
-
-```shell
-# from your local machine
-git remote add dokku dokku@dokku.me:ruby-rails-sample
-git push dokku master
-```
-
-You should see output similar to the following:
-
-```
-Counting objects: 231, done.
-Delta compression using up to 8 threads.
-Compressing objects: 100% (162/162), done.
-Writing objects: 100% (231/231), 36.96 KiB | 0 bytes/s, done.
-Total 231 (delta 93), reused 147 (delta 53)

-```
-
-When the deploy finishes, the application's URL will be shown.
-
-```shell
-=====> Application deployed:
-       http://ruby-rails-sample.dokku.me
-```
-
-Dokku supports deploying applications via [Heroku buildpacks](https://devcenter.heroku.com/articles/buildpacks) with [Herokuish](https://github.com/gliderlabs/herokuish#buildpacks) or using a project's [dockerfile](https://docs.docker.com/reference/builder/).
-
-### Removing a deployed app
-
-You can also remove an application from your Dokku installation. This will unlink all linked services and destroy any config related to the application. Note that linked services will retain their data for later use (or removal).
-
-```shell
-# on your dokku host
-# replace APP with the name of your application
-dokku apps:destroy APP
-```
-
-This will prompt you to verify the application's name before destroying it. You may also use the `--force` flag to circumvent this verification process:
-
-```shell
-# on your dokku host
-# replace APP with the name of your application
-dokku --force apps:destroy APP
-```
-
-### Renaming a deployed app
-
-> New as of 0.4.7
-
-You can rename a deployed app using the `apps:rename` CLI tool:
-
-```shell
-# on your dokku host
-dokku apps:rename OLD_NAME NEW_NAME
-```
-
-This will copy all of your app's contents into a new app directory with the name of your choice, delete your old app, then rebuild the new version of the app and deploy it. All of your config variables, including database urls, will be preserved.
-
-### Deploying non-master branch
-
-Dokku only supports deploying from its master branch, so if you'd like to deploy a different local branch use: ```git push dokku <local branch>:master```
-
-You can also support pushing multiple branches using the [receive-branch](/dokku/development/plugin-triggers/#receive-branch) plugin trigger in a custom plugin.
-
-### Skipping deployment
-
-If you only want to rebuild and tag a container, you can skip the deployment phase by setting `$DOKKU_SKIP_DEPLOY` to `true` by running:
-
-``` shell
-# on your dokku host
-dokku config:set ruby-rails-sample DOKKU_SKIP_DEPLOY=true
-```
-
-### Deploying with private git submodules
-
-Dokku uses git locally (i.e. not a docker image) to build its own copy of your app repo, including submodules. This is done as the `dokku` user. Therefore, in order to deploy private git submodules, you'll need to drop your deploy key in `/home/dokku/.ssh/` and potentially add github.com (or your VCS host key) into `/home/dokku/.ssh/known_hosts`. The following test should help confirm you've done it correctly.
-
-```shell
-# on your dokku host
-su - dokku
-ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts
-ssh -T git@github.com
-```
-
-Note that if the buildpack or dockerfile build process require ssh key access for other reasons, the above may not always apply.
-
-## Deploying to subdomains
-
-The name of remote repository is used as the name of application to be deployed, as for example above:
-
-    $ git remote add dokku dokku@dokku.me:ruby-rails-sample
-    $ git push dokku master
-
-Is deployed to,
-
-    remote: -----> Application deployed:
-    remote:        http://ruby-rails-sample.dokku.me
-
-You can also specify fully qualified names, say `app.dokku.me`, as
-
-    $ git remote add dokku dokku@dokku.me:app.dokku.me
-    $ git push dokku master
-
-So, after deployment the application will be available at,
-
-    remote: -----> Application deployed:
-    remote:        http://app.dokku.me
-
-This is in particular useful, then you want to deploy to root domain, as
-
-    $ git remote add dokku dokku@dokku.me:dokku.me
-    $ git push dokku master
-
-    ... deployment ...
-
-    remote: -----> Application deployed:
-    remote:        http://dokku.me
-
-## Dokku/Docker Container Management Compatibility
-
-Dokku is, at its core, a docker container manager. Thus, it does not necessarily play well with other out-of-band processes interacting with the docker daemon. One thing to note as in [issue #1220](https://github.com/dokku/dokku/issues/1220), dokku executes a cleanup function prior to every deployment.
-
-As of 0.5.x, this function removes all containers with the label `dokku` where the status is either `dead` or `exited`, as well as all `dangling` images. Previous versions would remove `dead` or `exited` containers, regardless of their label.
-
-## Adding deploy users
-
-See the [user management documentation](/dokku/deployment/user-management).
-
-## Default vhost
-
-See the [nginx documentation](/dokku/nginx/#default-site).
-
-## Dockerfile deployment
-
-See the [dockerfile documentation](/dokku/deployment/dockerfiles/).
-
-## Specifying a custom buildpack
-
-See the [buildpack documentation](/dokku/deployment/buildpacks/).
-
-## Image tagging
-
-See the [image tagging documentation](/dokku/deployment/images).
-
-## Zero downtime deploy
-
-See the [zero-downtime deploy documentation](/dokku/checks-examples/).
