+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.

 > 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.
@@ -20,50 +21,77 @@ The storage plugin supports the following mount points:
 
 ## Usage
 
-This example demonstrates how to mount the recommended directory to `/storage` inside an application called `node-js-app`. For simplicity, the Dokku project recommends using the directory `/var/lib/dokku/data/storage` directory as the root host path for mounts. This directory is created on Dokku installation.
+### Creating storage directories
+
+> New as of 0.25.5
+
+A storage directory can be created with the `storage:ensure-directory` command. This command will create a subdirectory in the recommended `/var/lib/dokku/data/storage` path - created during Dokku installation - and prepare it for use with an app.
 
 ```shell
-# we use a subdirectory inside of the host directory to scope it to just the app
-dokku storage:mount node-js-app /var/lib/dokku/data/storage/node-js-app:/storage
+dokku storage:ensure-directory lollipop
 ```
 
-Dokku will then mount the shared contents of `/var/lib/dokku/data/storage/node-js-app` to `/storage` inside the container. Mounts are only available for containers crated 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.
+```
+-----> Ensuring /var/lib/dokku/data/storage/lollipop exists
+       Setting directory ownership to 32767:32767
+       Directory ready for mounting
+```
 
-> If the `/storage` path within the container had pre-existing content, the container files will be overrwritten. 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.
+By default, permissions are set for usage with Herokuish buildpacks. These permissions can be changed via the `--chown` option according to the following table:
 
-Once you have mounted persistent storage, you will also need to restart the application. See the
-[process scaling documentation](/docs/processes/process-management.md) for more information.
+- `--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
 
-# set the directory ownership. Below is an example for herokuish
-# but see the `Directory Permissions` section for more details
-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.
 
-### Directory Permissions
-
-The host directory should always be owned by the container user and group id. If this is not the case, files may not persist when written to mounted storage.
-
-- Buildpacks via Herokuish: Use `32767:32767` as the file permissions
-- For Cloud Native Buildpacks: This will depend on the builder in question, but can be retrieved via the `CNB_USER_ID` and `CNB_GROUP_ID` environment variables on the builder image. Common builders are as follows:
-  - heroku/buildpacks: `1000:1000`
-  - cloudfoundry/cnb: `2000:2000`
-  - packeto: `2000:2000`
-- Dockerfile and Docker Image: Use the user and group id which corresponds to the one running the process within the container.

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 `formations` key of the `app.json` file.
+- 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
+
+- The `tags` plugin - deprecated in [0.24.0](/docs/appendices/0.24.0-migration-guide.md) - was removed. Users are highly encouraged to switch their workflows to `git:from-image`.
+- The `tar` plugin - deprecated in [0.24.0](/docs/appendices/0.24.0-migration-guide.md) - was removed. Users are highly encouraged to switch their workflows to `git:from-archive`.
+
+## Changes
+
+- The `scheduler` plugin now controls the scheduler in use for deploys. Apps will have their `DOKKU_SCHEDULER` environment variables migrated to the scheduler plugin, after which that value will be removed from said app. Please see the [scheduler documentation](/docs/deployment/schedulers/scheduler-management.md) for more information.
+- The `deploy-source` metadata from `apps:report` is now no longer computed on the fly, but hydrated at deploy time via the `deploy-source-set` trigger. This value may be empty until your next deploy.
+  - Additionally, the `deploy-source` trigger has now been removed.

-
-You can also create new tags for that app using the `tags:create` function. Tags should conform to the Docker tagging specification for your Docker version. As of 1.10, that specification is available [here](https://github.com/docker/docker/blob/master/image/spec/v1.1.md), while users of older versions can check the documentation [here](https://github.com/docker/docker/blob/master/image/spec/v1.md).
-
-```shell
-dokku tags:create node-js-app v1
-```
-
-```
-=====> Added v1 tag to dokku/node-js-app
-```
-
-Once the tag is created, you can see the output by running the `tags` command again.
-
-```shell
-dokku tags node-js-app
-```
-
-```
-=====> Image tags for dokku/node-js-app
-REPOSITORY          TAG                 IMAGE ID            CREATED              VIRTUAL SIZE

-```
-
-### Deploying an image tag
-
-Finally, you can also deploy a local image using the `tags:deploy` command. When specifying a tag that is not `latest`, the released image will be retagged as the `latest` image tag for the app.
-
-> Warning: For images based on Herokuish, using the `tags:deploy` command will reset environment variables written into the image, causing a retag to occur. This will - on average - add two extra layers to your deployed image. Note that this does not affect Dockerfile-based images, which are the majority of images deployed via the `tags` command.

-dokku tags:deploy node-js-app v1

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

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

+### Deploying Process Types in Parallel
+
+> New as of 0.25.5
+
+By default, Dokku deploys an app's processes one-by-one in order, with the `web` process being deployed first. Deployment parallelism may be achieved by setting the `parallel-schedule-count` property, which defaults to `1`. Increasing this number increases the number of process types that may be deployed in parallel (with the web process being the exception).
+
+```shell
+# Increase parallelism from 1 process type at a time to 4 process types at a time.
+dokku scheduler-docker-local:set node-js-app parallel-schedule-count 4
+```
+
+Once set, you may reset it by setting a blank value for `parallel-schedule-count`:
+
+```shell
+dokku scheduler-docker-local:set node-js-app parallel-schedule-count
+```
+
+If the value of `parallel-schedule-count` is increased and a given process type fails to schedule successfully, then any in-flight process types will continue to be processed, while all process types that have not been scheduled will be skipped before the deployment finally fails.
+
+Container scheduling output is shown in the order it is received, and thus may be out of order in case of output to stderr.
+
+Note that increasing the value of `parallel-schedule-count` may significantly impact CPU utilization on your host as your app containers - and their respective processes - start up. Setting a value higher than the number of available CPUs is discouraged. It is recommended that users carefully set this value so as not to overburden their server.
+
+#### Increasing parallelism within a process deploy
+
+> New as of 0.26.0
+
+By default, Dokku will deploy one instance of a given process type at a time. This can be increased by customizing the `app.json` `formation` key to include a `max_parallel` key for the given process type.
+
+An `app.json` file can be committed to the root of the pushed app repository, and must be within the built image artifact in the image's working directory as shown below.
+
+- Buildpacks: `/app/app.json`
+- Dockerfile: `WORKDIR/app.json` or `/app.json` (if no working directory specified)
+- Docker Image: `WORKDIR/app.json` or `/app.json` (if no working directory specified)
+
+The `formation` key should be specified as follows in the `app.json` file:
+
+```Procfile
+{
+  "formation": {
+    "web": {
+      "max_parallel": 1
+    },
+    "worker": {
+      "max_parallel": 4
+    }
+  }
+}
+```
+
+Omitting or removing the entry will result in parallelism for that process type to return to 1 entry at a time. This can be combined with the  `parallel-schedule-count` property to speed up deployments.
+
+Note that increasing the value of `max_parallel` may significantly impact CPU utilization on your host as your app containers - and their respective processes - start up. Setting a value higher than the number of available CPUs is discouraged. It is recommended that users carefully set this value so as not to overburden their server.

+
+Schedulers are a way of customizing how an app image is deployed, and can be used to interact with non-local systems such as Kubernetes and Nomad.
+
+## Usage
+
+### Scheduler selection
+
+Dokku supports the following built-in schedulers:
+
+- `scheduler-docker-local`: Schedules apps against the local docker socket and runs containers directly on the Dokku host. See the [docker-local scheduler documentation](/docs/deployment/schedulers/docker-local.md) for more information on how this scheduler functions.
+- `scheduler-null`: Does nothing during the scheduler phase. See the [null scheduler documentation](/docs/deployment/schedulers/null.md) for more information on how this scheduler functions.
+
+See the [alternate schedulers documentation](/docs/deployment/schedulers/alternate-schedulers.md) for more information on other scheduler plugins.
+
+### Overriding the auto-selected scheduler
+
+If desired, the scheduler can be specified via the `scheduler:set` command by speifying a value for `selected`. The selected scheduler will always be used.
+
+```shell
+dokku scheduler:set node-js-app selected docker-local
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku scheduler:set node-js-app selected
+```
+
+The `selected` property can also be set globally. The global default is an empty string, and auto-detection will be performed when no value is set per-app or globally.
+
+```shell
+dokku scheduler:set --global selected docker-local
+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell
+dokku scheduler:set --global selected
+```
+
+### Displaying scheduler reports for an app
+
+You can get a report about the app's scheduler status using the `scheduler:report` command:
+
+```shell
+dokku scheduler:report
+```
+
+```
+=====> node-js-app scheduler information
+       Scheduler computed selected:  herokuish
+       Scheduler global selected: herokuish

+       Scheduler computed selected: herokuish
+       Scheduler global selected: herokuish
+       Scheduler selected:

+
+You can run the command for a specific app also.
+
+```shell
+dokku scheduler:report node-js-app
+```
+
+```
+=====> node-js-app scheduler information
+       Scheduler selected: herokuish
+```
+
+You can pass flags which will output only the value of the specific information you want. For example:
+
+```shell
+dokku scheduler:report node-js-app --scheduler-selected
+```
+
+## Implementing a Scheduler
+
+Custom plugins names _must_ have the prefix `scheduler-` or scheduler overriding via `scheduler:set` may not function as expected.
+
+At this time, the following dokku commands are used to implement a complete scheduler.
+
+- `apps:destroy`: stops the app processes on the scheduler
+  - triggers: post-delete, scheduler-register-retired, scheduler-retire
+- `apps:rename`: handles app renaming
+  - triggers: post-app-rename-setup
+- `apps:clone`: handles app cloning
+  - triggers: post-app-clone-setup
+- `deploy`: deploys app proceses and checks the status of a deploy
+  - triggers: scheduler-app-status, scheduler-deploy, scheduler-is-deployed, scheduler-logs-failed
+- `enter`: enters a running container
+  - triggers: scheduler-enter
+- `logs`: fetches app logs
+  - triggers: scheduler-logs
+- `run`: starts one-off run containers (detached and non-detached) as well as listing run processes
+  - triggers: scheduler-run, scheduler-run-list
+- `ps:stop`: stops app processes
+  - triggers: scheduler-stop
+- `ps:inspect`: outputs inspect output for processes in an app
+  - triggers: scheduler-inspect
+
+Schedulers may decide to omit some functionality here, or use plugin triggers to supplement config with information from other plugins. Additionally, a scheduler may implement other triggers in order handle any extra processes needed during a deploy.
+
+Schedulers can use any tools available on the system to build the docker image, and may even be used to interact with off-server systems. The only current requirement is that the scheduler must have access to the image built in the build phase. If this is not the case, the registry plugin can be used to push the image to a registry that the scheduler software can access.
+
+Deployment tasks are currently executed directly on the primary Dokku server.

 # Getting Started with Dokku
 
-## What is Dokku?
+### What is Dokku?
 
-Dokku is an extensible, open source Platform as a Service that runs on a single server of your choice.
+Dokku is an extensible, open source Platform as a Service that runs on a single server of your choice. Dokku supports building apps on the fly from a `git push` via either Dockerfile or by auto-detecting the language with Buildpacks, and then starts containers based on your built image. Using technologies such as nginx and cron, Web processes are automatically routed to, while background processes and automated cron tasks are also managed by Dokku.
+
+### System Requirements
 
 To start using Dokku, you'll need a system that meets the following minimum requirements:
 
-- A fresh installation of [Ubuntu 18.04/20.04 x64](https://www.ubuntu.com/download), [Debian 9+ x64](https://www.debian.org/distrib/) or [CentOS 7 x64](https://www.centos.org/download/) *(experimental)* with the FQDN set <sup>[1]</sup>
-- At least 1 GB of system memory <sup>[2]</sup>
+- A fresh installation of any of the following operating systems:
+    - [Ubuntu 18.04/20.04 x64](https://www.ubuntu.com/download)
+    - [Debian 9+ x64](https://www.debian.org/distrib/)
+    - [CentOS 7 x64](https://www.centos.org/download/) *(experimental)*
+- A server with one of the following architectures
+    - AMD64 (alternatively known as `x86_64`), commonly used for Intel cloud servers 
+    - ARMV7 (alternatively known as `armhf`), commonly used for Raspberry PI
 
-Dokku is designed for usage on a fresh VM installation, and should install all necessary dependencies if installing via the bootstrap method.
+To avoid memory pressure during builds or runtime of your applications, we suggest the following:
+
+- At least 1 GB of system memory
+    - If your system has less than 1GB of memory, you can use [this workaround](/docs/getting-started/advanced-installation.md#vms-with-less-than-1gb-of-memory).
+
+Finally, we recommend attaching at least one domain name to your server. This is not required, but using a domain name will make app access easier. When connecting a domain, either a single domain or a wildcard may be associated to the server's IP.
+
+- Wildcard domain (`*.domain.tld` A Record): will allow access to apps via `$APP.domain.tld`.
+- Single domain (`domain.tld` A or CNAME Record): will result in apps being accessed via `domain.tld:$RANDOM_PORT`.
+
+Please see the [dns documentation](/docs/networking/dns.md) and [domains documentation](/docs/configuration/domains.md) for more details.
 
 ### Installing the latest stable version
 
+This is the simple method of installing Dokku. For alternative methods of installation, see the [advanced install guide](/docs/getting-started/advanced-installation.md#configuring). 
+
 #### 1. Install Dokku
 
 To install the latest stable version of Dokku, you can run the following shell commands:
 
 ```shell
 # for debian systems, installs Dokku via apt-get
-wget https://raw.githubusercontent.com/dokku/dokku/v0.25.2/bootstrap.sh;
-sudo DOKKU_TAG=v0.25.2 bash bootstrap.sh
+wget https://raw.githubusercontent.com/dokku/dokku/v0.27.2/bootstrap.sh;
+sudo DOKKU_TAG=v0.27.2 bash bootstrap.sh
 ```
 
 The installation process takes about 5-10 minutes, depending upon internet connection speed.
 
-If you're using Debian 9+ or Ubuntu 18.04, make sure your package manager is configured to install a sufficiently recent version of nginx<sup>[3]</sup>, otherwise, the installation may fail due to `unmet dependencies` relating nginx.
+#### 2. Setup SSH key and Virtualhost Settings
 
-#### 2. Optionally connect a domain to your server
-
-Dokku optionally supports one or more domain names. If you do not own a domain name, you may either purchase one or skip this step.
-
-When connecting a domain, either a single domain or a wildcard may be associated to the server's IP. A wildcard domain will allow access to apps via `$APP.domain.tld`, whereas associating only a single domain name will result in apps being access via `domain.tld:$RANDOM_PORT`. Please see the [dns documentation](/docs/networking/dns.md) and [domains documentation](/docs/configuration/domains.md) for more details.
-
-#### 3. Setup SSH key and Virtualhost Settings
-
-Once the installation is complete, you should configure an ssh key and set your global domain:from-archive
+Once the installation is complete, you should configure an ssh key and set your global domain.

+
+# you can also use the ip of your server
+dokku domains:set-global 10.0.0.2
+
+# finally, you can use sslip.io to get subdomain support

+Using the `EXPOSE` directive in a Dockerfile may be another reason why you might see the default site. When the `EXPOSE` directive is in use and a proxy plugin is enabled (the default), the proxy plugin will listen to requests on the ports specified in the `EXPOSE` stanza.
+
+For example, if you have an `EXPOSE` directive like so:
+
+```Dockerfile
+EXPOSE 8000
+```
+
+The proxy port mapping will be `http:8000:8000`.
+
+To avoid this issue, either of the following can be done:
+
+- Remove `EXPOSE` directive: This will require respecting the `$PORT` environment variable (automatically set by Dokku). Once that change is deployed, the port mapping should be cleared via the `dokku proxy:ports-clear $APP` command (where `$APP` is your app name).
+- Update the port mapping: Updating the port mapping to redirect port `80` to your app's exposed port via `dokku proxy:ports-set $APP http:80:$EXPOSED_PORT` can also fix the issue. This will also allow certificate management and the letsencrypt plugin to work correctly.
+
+See the [port management documentation](/docs/networking/port-management.md) for more information on how Dokku exposes ports for applications and how you can configure these for your app.

+### Restoring apps after a server reboot
+
+When a server reboots or Docker is restarted/upgraded, Docker may or may not start old app containers automatically, and may in some cases re-assign container IP addresses. To combat this issue, Dokku uses an init process that triggers `dokku ps:restore` after the Docker daemon is detected as starting. When triggered, the `dokku ps:restore` command will serially (one by one) run the following for each:
+
+- Start all linked services.
+- Clear generated proxy configuration files.
+- Start the app if it has not been manually stopped.
+  - If the app containers still exist, they will be started and the generated proxy configuration files will be rebuilt.
+  - If any of the app containers are missing, the entire app will be rebuilt.
+
+During this time, requests may route to the incorrect app if the assigned IPs correspond to those for other apps. While dokku makes all efforts to avoid this, there may be a few minutes where urls may route to the wrong app. To avoid this, either use a custom proxy plugin or wait a few minutes until the restoration process is complete.
