+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

-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail

 ## Requirements
 
 A fresh VM running any of the following operating systems:
 
-- Ubuntu x64 - Any currently supported release
-- Debian 8.2+ x64
-- CentOS 7 x64 *(experimental)*
+- 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/v0.16.2/bootstrap.sh
-sudo DOKKU_TAG=v0.16.2 bash bootstrap.sh
+wget https://raw.githubusercontent.com/dokku/dokku/v0.29.2/bootstrap.sh
+sudo DOKKU_TAG=v0.29.2 bash bootstrap.sh
 ```
 
-You can then proceed to the ip address or domain name associated with your server to complete the web-based installation.

-## Backup and Migration Tutorial
+The best plan for disaster recovery is to always keep multiple (remote) copies of your local repo, static assets and periodic database dumps. Backups should be regularly tested for data integrity and completeness.
+
+## TLDR
+
+> Warning: This method has many caveats. Please read this entire document before assuming these backups work as expected, and test your backups on a regular basis.
+
+### Creating a backup
+
+To create a backup, run the following command at a time when not executing any Dokku commands or app deployments:
+
+```shell
+export BACKUP_TIME=$(date +%Y-%m-%d-%H-%M)
+sudo mkdir -p /var/lib/dokku/services
+sudo chown dokku:dokku /var/lib/dokku/services
+mkdir -p /tmp/dokku-backups/
+sudo tar -czvf "/tmp/dokku-backups/${BACKUP_TIME}.tar.gz" /home/dokku /var/lib/dokku/config /var/lib/dokku/data /var/lib/dokku/services /var/lib/dokku/plugins
+```
+
+This will create a point-in-time backup of your entire Dokku installation in the `/tmp/dokku-backups` directory. This backup may be moved offsite to another location via rsync, sftp, or some other protocol.
+
+It is recommended that backups are regularly cleaned from the originating server and tested as necessary.
+
+### Restoring a backup
+
+To extract the backup onto another server, copy the backup to the server and extract it using the following command.
+
+```shell
+sudo tar -xzvf path/to/dokku/backup.tar.gz -C /
+```
+
+At this point, all datastores should be individually started and checked for data integrity. Once this is complete, individual apps can be rebuilt. Please consult the [process management documentation](/docs/processes/process-management.md#rebuilding-apps) for more information on how to rebuild apps.
+
+## Caveats
+
+### App config
+
+Application config is largely held in a small number of places:
+
+- `/var/lib/dokku/config`: Properties set and managed by plugins
+- `/var/lib/dokku/data`: Files generated or extracted by various plugins
+- `/home/dokku`: Certain parts of Dokku core store data in this location
+
+Compressing these directories when no Dokku commands are running is enough to ensure a complete backup of the system.
+
+### Code Repositories
 
 Because Dokku is git based, rebuilding a deployed app is as easy as pushing from git. You can push to a new server by updating the `dokku` remote in you local app's repo.
 
@@ -11,7 +55,20 @@ git remote rm dokku
 git remote add dokku dokku@[dokku.me:dokku.me]
 git push dokku [master]
 ```
-## Databases
+
+### 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.

-## Volumes and Static Assets
+Additionally, data for official datastores is located in the `/var/lib/dokku/services` directory. If the directory is restored and the plugin is available, a `dokku $SERVICE:start` may be enough to restart the service with the underlying data, so long as the datastore version does not change and the underlying data is not corrupt. If this is the case, it may be necessary to re-import all the data onto a fresh version of the datastore service.
+
+### Plugins
+
+The plugin directory is contained at the `/var/lib/dokku/plugins` directory. Core plugins will automatically be included in new installs, but custom plugins may not. The aforementioned `tar` creation command will back all plugins up, and the `tar` extract command will restore the plugins.
+
+Note that restoring a plugin will not trigger any `install` or `dependencies` triggers. You will need to run these manually. See the [plugin management documentation](/docs/advanced-usage/plugin-management.md#installing-a-plugin) for more information on how to trigger these two hooks.
+
+### Volumes and Static Assets
 
 Dokku doesn't enforce a [300mb](https://devcenter.heroku.com/articles/slug-compiler#slug-size) limit on apps, but it's best practice to keep binary assets outside of git. Since containers are considered volatile in Dokku, external stores like s3 or storage mounts should be used for non-volatile items like user uploads. The Dokku storage core plugin can be used to mount local directories / volumes inside the docker container.
 
-See the [persistent storage documentation](/docs/advanced-usage/persistent-storage.md) for more details.
+System administrators are highly encouraged to store persistent data in app-specific subdirectories of the path `/var/lib/dokku/data/storage`. This will help ensure restores of the aforementioned primary Dokku directories will restore service to all apps.
 
+See the [persistent storage documentation](/docs/advanced-usage/persistent-storage.md) for more information on how to attach persistent storage to your app.

-## `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:
+
+```shell
+dokku app-json:report
+```
+
+```
+=====> node-js-app app-json information
+       App-json computed appjson path: app2.json
+       App-json global appjson path:   app.json

+       App-json computed appjson path: app.json
+       App-json global appjson path:   app.json
+       App-json appjson path:
+```
+
+You can run the command for a specific app also.
+
+```shell
+dokku app-json:report node-js-app

+
+```
+=====> node-js-app app-json information
+       App-json computed appjson path: app2.json
+       App-json global appjson path:   app.json
+       App-json appjson path:          app2.json
+```
+
+You can pass flags which will output only the value of the specific information you want. For example:
+
+```shell
+dokku app-json:report node-js-app --app-json-appjson-path
+```
+
+```

-- 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` to `/storage` inside the container.
+```
+-----> Ensuring /var/lib/dokku/data/storage/lollipop exists
+       Setting directory ownership to 32767:32767
+       Directory ready for mounting
+```
 
-Once you have mounted persistent storage, you will also need to restart the application. See the
-[process scaling documentation](/docs/deployment/process-management.md) for more information.
+By default, permissions are set for usage with Herokuish buildpacks. These permissions can be changed via the `--chown` option according to the following table:
+
+- `--chown herokuish` (default): Use `32767:32767` as the folder permissions.
+  - This is used for apps deployed with Buildpacks via Herokuish.
+- `--chown heroku`: Use `1000:1000` as the folder permissions.
+  - This is used for apps deployed with Cloud Native Buildpacks using the `heroku/buildpacks` builder.
+- `--chown packeto`: Use `2000:2000` as the folder permissions.
+  - This is used for apps deployed with Cloud Native Buildpacks using the `cloudfoundry/cnb` or `packeto` builders.
+- `--chown false`: Skips the `chown` call.
+
+Users deploying via Dockerfile will want to specify `--chown false` and manually `chown` the created directory if the user and/or group id  of the runnning process in the deployed container do not correspond to any of the above options.
+
+> Warning: Failing to set the correct directory ownership may result in issues in persisting files written to the mounted storage directory.
+
+### Mounting storage into apps
+
+Dokku supports mounting both explicit host paths as well as docker volumes via the `storage:mount` command. This takes two arguments, an app name and a `host-path:container-path` or `docker-volume:container-path` combination.
+
+```shell
+# mount the directory into your container's /app/storage directory, relative to the container root (/)
+# explicit host paths _must_ exist prior to usage.
+dokku storage:mount node-js-app /var/lib/dokku/data/storage/node-js-app:/app/storage
+
+# mount the docker volume into your container's /app/storage directory, relative to the container root (/)
+# docker volumes _must_ exist prior to usage.
+dokku storage:mount node-js-app some-docker-volume:/app/storage
+```
+
+In the first example, Dokku will then mount the shared contents of `/var/lib/dokku/data/storage/node-js-app` to `/app/storage` inside the container.  The mount point is *not* relative to your app's working directory, and is instead relative to the root (`/`) of the container. Mounts are only available for containers created via `run` and by the deploy process, and not during the build process. In addition, the host path is never auto-created by either Dokku or Docker, and should be an explicit path, not one relative to the current working directory.
+
+> If the `/storage` path within the container had pre-existing content, the container files will be over-written. This may be an issue for users that create assets at build time but then mount a directory at the same place during runtime. Files are not merged.
+
+Once persistent storage is mounted, the app requires a restart. See the [process scaling documentation](/docs/processes/process-management.md) for more information.
 
 ```shell
 dokku ps:restart app-name
 ```
 
-A more complete workflow may require making a custom directory for your application and mounting it within your `/app/storage` directory instead. The mount point is *not* relative to your application's working directory, and is instead relative to the root of the container.
+### Unmounting storage
+
+If an app no longer requires a mounted volume or directory, the `storage:unmount` command can be called. This takes the same arguments as the `storage:mount` command, an app name and a `host-path:container-path` or `docker-volume:container-path` combination.
 
 ```shell
-# creating storage for the app 'node-js-app'
-mkdir -p  /var/lib/dokku/data/storage/node-js-app
+# unmount the directory from your container's /app/storage directory, relative to the container root (/)
+dokku storage:unmount node-js-app /var/lib/dokku/data/storage/node-js-app:/app/storage
 
-# ensure the proper user has access to this directory
-chown -R dokku:dokku /var/lib/dokku/data/storage/node-js-app
-
-# as of 0.7.x, you should chown using the `32767` user and group id for buildpack deploys
-# For dockerfile deploys, substitute the user and group id in use within the image
-chown -R 32767:32767 /var/lib/dokku/data/storage/node-js-app
-
-# mount the directory into your container's /app/storage directory, relative to root
-dokku storage:mount app-name /var/lib/dokku/data/storage/node-js-app:/app/storage
+# unmount the docker volume from your container's /app/storage directory, relative to the container root (/)
+dokku storage:unmount node-js-app some-docker-volume:/app/storage
 ```
 
-You can mount one or more directories as desired by following the above pattern.
+Once persistent storage is unmounted, the app requires a restart. See the [process scaling documentation](/docs/processes/process-management.md) for more information.
+
+```shell
+dokku ps:restart app-name

+```shell
+dokku plugin:install-dependencies

+```
+
+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

-> 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
-```

+
+## 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)

+
+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
+

+### 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`.

+- `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`.

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

+## Deprecations
+
+- Calling `logs:failed` without either a `<name>` or the `--all` flag is deprecated.
+
+## Changes
+
+- Underscores are no longer valid characters in app names. Please rename applications before upgrading.
+- Process type names specified in Procfile may no longer use characters not valid in DNS Label Names ([RFC 1123](https://tools.ietf.org/html/rfc1123)).
+- The minimum Docker version is now 17.05.0.
+- The `common.GetDeployingAppImageName()` function now returns an `error` as the second return argument instead of calling `common.LogFail()` internally.
+- Setting `DOKKU_DISABLE_ANSI_PREFIX_REMOVAL` is deprecated; Dokku 0.23.0 will avoid removing the `remote:` ansi prefix entirely. No warning will be added in this release.
+
+## Removals
+
+The `ps` command has had a few removals as a result of a rewrite to Golang:
+
+- The `ps:set-restart-policy` command has been removed in favor the `ps:set` command.
+- The `ps:restart-policy` command has been removed in favor of the `ps:report` command.
+- The `ps:rebuildall` command has been removed in favor of calling the `ps:rebuild` with the `--all` flag instead of an app name.
+- The `ps:restartall` command has been removed in favor of calling the `ps:restart` with the `--all` flag instead of an app name.
+- The `ps:stopall` command has been removed in favor of calling the `ps:stop` with the `--all` flag instead of an app name.
+- The `ps:startall` command has been removed in favor of calling the `ps:start` with the `--all` flag instead of an app name.
+- The `DOKKU_PROCFILE` file is no longer located in the git directory for a given app on the server. It's location is currently not exposed.
+- The `procfile-get-command` plugin trigger no longer takes a `procfile path` as the final argument.
+- All `ps` functions have been removed. Please us a trigger as appropriate or file a PR to have a new trigger/wrapper function added.

+## Changes
+
+- 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.

+## Changes
+
+- The commands `proxy:enable`, `proxy:disable` and `proxy:build-config` now support the `--all` flag in addition to general parallelism.
+- The `builder-cnb` plugin has been renamed `builder-pack`, and all related plugin triggers have had the suffix `-cnb` changed to `-pack`.
+
+## Deprecations
+
+- The 1.0.0 release of Dokku will no longer select buildpack builders over dockerfile builders if both builders match. Instead, Dokku will choose the first builder that responds to the `builder-detect` trigger. Users that wish to use a specific builder may set a builder using the `builder:set` command, which will force Dokku to use the specified builder regardless of what might be auto-detected.
+- The `tags` plugin is deprecated in favor of the [`git:from-image`](/docs/deployment/methods/git.md#initializing-an-app-repository-from-a-docker-image) command. It will be removed in the next minor release, and is considered unmaintained. Users are highly encouraged to switch their workflows to `git:from-image`.

+
+## 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/advanced-usage/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.
