+# 0.28.0 Migration Guide
+
+## Removals
+
+Support for the following operating systems has been removed:
+
+- CentOS 7
+- Debian 9 (Stretch)
+- Fedora
+- OpenSuse
+
+Dokku will no longer provide packages for RPM based systems. Debian 9 users _may_ use new Debian packages, though support is not guaranteed.
+
+All users are encouraged to install Dokku via the [Docker-based installation method](/docs/getting-started/install/docker.md), or switch to a supported operating system.
+
+## Deprecations
+
+Ubuntu 18.04 is now a deprecated installation target. The operating system will be considered EOL by Canonical in April 2023. Users are encouraged to upgrade to Ubuntu 22.04 or consider switching their instllation method to the [Docker-based installation method](/docs/getting-started/install/docker.md) to avoid any disruption in usage.
+
+## Additions
+
+New in 0.28.0 are the Caddy and Traefik plugins. As community plugins wrapping these proxies exist, users should:
+
+- Recommended: Uninstall the community plugin in question and switch all config to the new plugins.
+- Upgrade the community plugin to a version that does not use the `proxy:set` value of `caddy` or `traefik`.

+# Lambda Builder
+
+> New as of 0.28.0
+
+The `lambda` builder builds AWS Lambda functions in an environment simulating AWS Lambda runtimes via [lambda-builder](https://github.com/dokku/lambda-builder). Apps built via this builder can run natively in Dokku and may also have their artifacts scheduled to Lambda via an appropriate scheduler.
+
+## Usage
+
+### Detection
+
+This builder will be auto-detected in the following case:
+
+- A `lambda.yml` exists in the root of the app repository.
+
+The builder may also be selected via the `builder:set` command
+
+```shell
+dokku builder:set node-js-app selected lambda
+```
+
+### Supported languages
+
+The `lambda` builder plugin supports the following AWS runtime languages on Amazon Linux 2:
+
+- dotnet
+- go (builder is based on AL1)
+- nodejs
+- python
+- ruby
+
+See the [lambda-builder](https://github.com/dokku/lambda-builder#how-does-it-work) documentation for more information on how specific languages are detected.
+
+### Customizing the build environment
+
+The `lambda` builder plugin delegates all build logic to [lambda-builder](https://github.com/dokku/lambda-builder), including language detection and build/runtime environment specification. The lambda-builder tool supports a `lambda.yml` file format for customizing how apps are built. Please see the readme for lambda-builder for more information on different options.
+
+### Changing the `lambda.yml` location
+
+When deploying a monorepo, it may be desirable to specify the specific path of the `lambda.yml` file to use for a given app. This can be done via the `builder-lambda:set` command. If a value is specified and that file does not exist in the app's build directory, then the build will fail.
+
+```shell
+dokku builder-lambda:set node-js-app lambdayml-path lambda2.yml
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku builder-lambda:set node-js-app lambdayml-path
+```
+
+The `lambdayml-path` property can also be set globally. The global default is `lambda.yml`, and the global value is used when no app-specific value is set.
+
+```shell
+dokku builder-lambda:set --global lambdayml-path lambda2.yml
+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell
+dokku builder-lambda:set --global lambdayml-path
+```
+
+### Displaying builder-lambda reports for an app
+
+You can get a report about the app's storage status using the `builder-lambda:report` command:
+
+```shell
+dokku builder-lambda-json:report
+```
+
+```
+=====> node-js-app builder-lambda information
+       Builder-lambda computed lambdayml path: lambda2.yml

+```
+

+# Caddy Proxy
+
+> New as of 0.28.0
+
+Dokku provides integration with the [Caddy](https://caddyserver.com/) proxy service by utilizing the Docker label-based integration implemented by Caddy.
+
+```
+caddy:report [<app>] [<flag>]            # Displays a caddy report for one or more apps
+caddy:logs [--num num] [--tail]          # Display caddy log output
+caddy:set <app> <property> (<value>)     # Set or clear an caddy property for an app
+caddy:show-config <app>                  # Display caddy compose config
+caddy:start                              # Starts the caddy server
+caddy:stop                               # Stops the caddy server
+```
+
+## Requirements
+
+Using the `caddy` plugin integration requires the `docker-compose-plugin` for Docker. See [this document](https://docs.docker.com/compose/install/compose-plugin/) from the Docker documentation for more information on the installation process for the `docker-compose-plugin`.
+
+## Usage
+
+> Warning: As using multiple proxy plugins on a single Dokku installation can lead to issues routing requests to apps, doing so should be avoided. As the default proxy implementation is nginx, users are encouraged to stop the nginx service before switching to Caddy.
+
+The Caddy plugin has specific rules for routing requests:
+
+- Caddy integration is exposed via docker labels attached to containers. Changes in labels require either app deploys or rebuilds.
+- While Caddy will respect labels associated with other containers, only `web` containers have Caddy labels injected by the plugin.
+- Only `http:80` and `https:443` port mappings are supported.
+- Caddy will automatically enable SSL if the letsencrypt email property is set. SSL will be disabled otherwise.
+- If no `http:80` mapping is found, the first `http` port mapping is used for http requests.
+- If no `https:443` mapping is found, the first `https` port mapping is used for https requests.
+- If no `https` mapping is found, the container port from `http:80` will be used for https requests.
+- Requests are routed as soon as the container is running and passing healthchecks.
+
+### Switching to Caddy
+
+To use the Caddy plugin, use the `proxy:set` command for the app in question:
+
+```shell
+dokku proxy:set node-js-app caddy
+```
+
+This will enable the docker label-based Caddy integration. All future deploys will inject the correct labels for Caddy to read and route requests to containers. Due to the docker label-based integration used by Caddy, a single deploy or rebuild will be required before requests will route successfully.
+
+```shell
+dokku ps:rebuild node-js-app
+```
+
+Any changes to domains or port mappings will also require either a deploy or rebuild.
+
+### Starting Caddy container
+
+Caddy can be started via the `caddy:start` command. This will start a Caddy container via the `docker compose up` command.
+
+```shell
+dokku caddy:start
+```
+
+### Stopping the Caddy container
+
+Caddy may be stopped via the `caddy:stop` command.
+
+```shell
+dokku caddy:stop
+```
+
+The Caddy container will be stopped and removed from the system. If the container is not running, this command will do nothing.
+
+### Showing the Caddy compose config
+
+For debugging purposes, it may be useful to show the Caddy compose config. This can be achieved via the `caddy:show-config` command.
+
+```shell
+dokku caddy:show-config
+```
+
+### Customizing the Caddy container image
+
+While the default Caddy image is hardcoded, users may specify an alternative by setting the `image` property with the `--global` flag:
+
+```shell
+dokku caddy:set --global image lucaslorentz/caddy-docker-proxy:2.7
+```
+
+#### Checking the Caddy container's logs
+
+It may be necessary to check the Caddy container's logs to ensure that Caddy is operating as expected. This can be performed with the `caddy:logs` command.
+
+```shell
+dokku caddy:logs
+```
+
+This command also supports the following modifiers:
+
+```shell
+--num NUM        # the number of lines to display
+--tail           # continually stream logs
+```
+
+You can use these modifiers as follows:
+
+```shell
+dokku caddy:logs --tail --num 10
+```
+
+The above command will show logs continually from the vector container, with an initial history of 10 log lines
+
+### Changing the Caddy log level
+
+Caddy log output is set to `ERROR` by default. It may be changed by setting the `log-level` property with the `--global` flag:
+
+```shell
+dokku caddy:set --global log-level DEBUG
+```
+
+After modifying,  the Caddy container will need to be restarted.
+
+### SSL Configuration
+
+The caddy plugin only supports automatic ssl certificates from it's letsencrypt integration. Managed certificates provided by the `certs` plugin are ignored.
+
+#### Enabling letsencrypt integration
+
+By default, letsencrypt is disabled and https port mappings are ignored. To enable, set the `letsencrypt-email` property with the `--global` flag:
+
+```shell
+dokku caddy:set --global letsencrypt-email automated@dokku.sh
+```
+
+After enabling, the Caddy container will need to be restarted and apps will need to be rebuilt. All http requests will then be redirected to https.
+
+#### Customizing the letsencrypt server
+
+The letsencrypt integration is set to the production letsencrypt server by default. To change this, set the `letsencrypt-server` property with the `--global` flag:
+
+```shell
+dokku caddy:set --global letsencrypt-server https://acme-staging-v02.api.letsencrypt.org/directory
+```
+
+After enabling, the Caddy container will need to be restarted and apps will need to be rebuilt to retrieve certificates from the new server.

+# Traefik Proxy
+
+> New as of 0.28.0
+
+Dokku provides integration with the [Traefik](https://traefik.io/) proxy service by utilizing the Docker label-based integration implemented by Traefik.
+
+```
+traefik:report [<app>] [<flag>]          # Displays a traefik report for one or more apps
+traefik:logs [--num num] [--tail]        # Display traefik log output

+traefik:stop                             # Stops the traefik server
+```
+
+## Requirements
+
+Using the `traefik` plugin integration requires the `docker-compose-plugin` for Docker. See [this document](https://docs.docker.com/compose/install/compose-plugin/) from the Docker documentation for more information on the installation process for the `docker-compose-plugin`.
+
+## Usage
+
+> Warning: As using multiple proxy plugins on a single Dokku installation can lead to issues routing requests to apps, doing so should be avoided. As the default proxy implementation is nginx, users are encouraged to stop the nginx service before switching to Traefik.
+
+The Traefik plugin has specific rules for routing requests:
+
+- Traefik integration is exposed via docker labels attached to containers. Changes in labels require either app deploys or rebuilds.
+- While Traefik will respect labels associated with other containers, only `web` containers have Traefik labels injected by the plugin.
+- Only `http:80` and `https:443` port mappings are supported.
+- If no `http:80` mapping is found, the first `http` port mapping is used for http requests.
+- If no `https:443` mapping is found, the first `https` port mapping is used for https requests.
+- If no `https` mapping is found, the container port from `http:80` will be used for https requests.
+- Requests are routed as soon as the container is running and passing healthchecks.
+
+### Switching to Traefik
+
+To use the Traefik plugin, use the `proxy:set` command for the app in question:
+
+```shell
+dokku proxy:set node-js-app traefik
+```
+
+This will enable the docker label-based Traefik integration. All future deploys will inject the correct labels for Traefik to read and route requests to containers. Due to the docker label-based integration used by Traefik, a single deploy or rebuild will be required before requests will route successfully.
+
+```shell
+dokku ps:rebuild node-js-app
+```
+
+Any changes to domains or port mappings will also require either a deploy or rebuild.
+
+### Starting Traefik container
+
+Traefik can be started via the `traefik:start` command. This will start a Traefik container via the `docker compose up` command.
+
+```shell
+dokku traefik:start
+```
+
+### Stopping the Traefik container
+
+Traefik may be stopped via the `traefik:stop` command.
+
+```shell
+dokku traefik:stop
+```
+
+The Traefik container will be stopped and removed from the system. If the container is not running, this command will do nothing.
+
+### Showing the Traefik compose config
+
+For debugging purposes, it may be useful to show the Traefik compose config. This can be achieved via the `traefik:show-config` command.
+
+```shell
+dokku traefik:show-config
+```
+
+### Customizing the Traefik container image
+
+While the default Traefik image is hardcoded, users may specify an alternative by setting the `image` property with the `--global` flag:
+
+```shell
+dokku traefik:set --global image traefik:v2.8
+```
+
+#### Checking the Traefik container's logs
+
+It may be necessary to check the Traefik container's logs to ensure that Traefik is operating as expected. This can be performed with the `traefik:logs` command.
+
+```shell
+dokku traefik:logs
+```
+
+This command also supports the following modifiers:
+
+```shell
+--num NUM        # the number of lines to display
+--tail           # continually stream logs
+```
+
+You can use these modifiers as follows:
+
+```shell
+dokku traefik:logs --tail --num 10
+```
+
+The above command will show logs continually from the vector container, with an initial history of 10 log lines
+
+### Changing the Traefik log level
+
+Traefik log output is set to `ERROR` by default. It may be changed by setting the `log-level` property with the `--global` flag:
+
+```shell
+dokku traefik:set --global log-level DEBUG
+```
+
+After modifying,  the Traefik container will need to be restarted.
+
+### SSL Configuration
+
+The traefik plugin only supports automatic ssl certificates from it's letsencrypt integration. Managed certificates provided by the `certs` plugin are ignored.
+
+#### Enabling letsencrypt integration
+
+By default, letsencrypt is disabled and https port mappings are ignored. To enable, set the `letsencrypt-email` property with the `--global` flag:
+
+```shell
+dokku traefik:set --global letsencrypt-email automated@dokku.sh
+```
+
+After enabling, apps will need to be rebuilt and the Traefik container will need to be restarted. All http requests will then be redirected to https.
+
+#### Customizing the letsencrypt server
+
+The letsencrypt integration is set to the production letsencrypt server by default. To change this, set the `letsencrypt-server` property with the `--global` flag:
+
+```shell
+dokku traefik:set --global letsencrypt-server https://acme-staging-v02.api.letsencrypt.org/directory
+```
+
+After enabling, the Traefik container will need to be restarted and apps will need to be rebuilt to retrieve certificates from the new server.
+
+### API Access
+
+Traefik exposes an API and Dashboard, which Dokku disables by default for security reasons. It can be exposed and customized as described below.
+
+#### Enabling the api
+
+> Warning: Users enabling the dashboard should also enable api basic auth.
+
+By default, the api is disabled. To enable, set the `api` property with the `--global` flag:
+
+```shell
+dokku traefik:set --global api true
+```
+
+After enabling, the Traefik container will need to be restarted.
+
+#### Enabling the dashboard
+
+> Warning: Users enabling the dashboard should also enable api basic auth.
+
+By default, the dashboard is disabled. To enable, set the `dashboard` property with the `--global` flag:
+
+```shell
+dokku traefik:set --global dashboard true
+```
+
+After enabling, the Traefik container will need to be restarted.
+
+#### Enabling api basic auth
+
+Users enabling either the api or dashboard are encouraged to enable basic auth. This will apply _only_ to the api/dashboard, and not to apps. To enable, set the `basic-auth-username` and `basic-auth-password` properties with the `--global` flag:. Both must be set or basic auth will not be enabled.
+
+```shell
+dokku traefik:set --global basic-auth-username username
+dokku traefik:set --global basic-auth-password password
+```
+
+After enabling, the Traefik container will need to be restarted.
+
+#### Customizing the api hostname
+
+The hostname used for the api and dashboard is set to `traefik.dokku.me` by default. It can be customized by setting the `api-vhost` property with the `--global` flag:
+
+```shell
+dokku traefik:set --global api-vhost lb.dokku.me
+```
+
+After enabling, the Traefik container will need to be restarted.
+
+## Displaying Traefik reports for an app

 From Dokku versions `0.5.0` until `0.11.0`, enabling or disabling an application's proxy would **also** control whether or not the application was bound to all interfaces - e.g. `0.0.0.0`. As of `0.11.0`, this is now controlled by the network plugin. Please see the [network documentation](/docs/networking/network.md#container-network-interface-binding) for more information.
+
+## Implementing a Proxy
+
+Custom plugins names _must_ have the suffix `-vhosts` or scheduler overriding via `proxy:set` may not function as expected.
+
+At this time, the following dokku commands are used to implement a complete proxy implementation. 
+
+- `domains:add`: Adds a given domain to an app.
+  - trigers: `post-domains-update`
+- `domains:clear`: Clears out an app's associated domains.
+  - trigers: `post-domains-update`
+- `domains:disable`: Disables domains for an app.
+  - trigers: `pre-disable-vhost`
+- `domains:enable`: Enables domains for an app.
+  - trigers: `pre-enable-vhost`
+- `domains:remove`: Removes a domain from an app.
+  - trigers: `post-domains-update`
+- `domains:set`: Sets all domains for a given app.
+  - trigers: `post-domains-update`
+- `proxy:build-config`: Builds - or rebuilds - external proxy configuration.
+  - triggers: `proxy-build-config`
+- `proxy:clear-config`: Clears out external proxy configuration.
+  - triggers: `proxy-clear-config`
+- `proxy:disable`: Disables the proxy configuration for an app.
+  - triggers: `proxy-disable`
+- `proxy:enable`: Enables the proxy configuration for an app.
+  - triggers: `proxy-enable`
+- `proxy:ports-add`: Adds one or more port mappings to an app
+  - triggers: `post-proxy-ports-update`
+- `proxy:ports-clear`: Clears out all port mappings for an app.
+  - triggers: `post-proxy-ports-update`
+- `proxy:ports-remove`: Removes one or more port mappings from an app.
+  - triggers: `post-proxy-ports-update`
+- `proxy:ports-set`: Sets all port mappings for an app.
+  - triggers: `post-proxy-ports-update`
+
+Proxy implementations may decide to omit some functionality here, or use plugin triggers to supplement config with information from other plugins.
+
+Individual proxy implementations _may_ trigger app rebuilds, depending on how proxy metadata is exposed for the proxy implementation.
+
+Finally, proxy implementations _may_ install extra software needed for the proxy itself in whatever manner deemed fit. Proxy software can run on the host itself or within a running Docker container with either exposed ports or host networking.
