+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.

+
+## 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

+### `user-auth-app`
+
+This is a special plugin trigger that is executed when listing apps or checking if an app exists. All Dokku commands should check if an app exists at least once before interacting with them so as not to circumvent the check.

+The `SSH_USER` is the original ssh user. If you are running remote commands, this user will typically be `dokku`, and as such should not be trusted when checking permissions.

+
+The `SSH_NAME` is the `NAME` variable set via the `sshcommand acl-add` command. For reference, the following command can be run as the root user to specify a specific `NAME` for a given ssh key:
+
+```shell

Finally, Dokku Pro provides an alternative, https-based method for deploying code which can be used in environments that lockdown ssh access to servers.
+
+## Purchasing
+
+Dokku Pro may be purchased online by clicking the following purchase link:
+
+<a data-dpd-type="button" data-text="PURCHASE NOW" data-variant="price-right" data-button-size="dpd-large" data-bg-color="469d3d" data-bg-color-hover="5cc052" data-text-color="ffffff" data-pr-bg-color="ffffff" data-pr-color="000000" data-lightbox="1" href="https://dokku.dpdcart.com/cart/add?product_id=217344&amp;method_id=236878">Dokku Pro Purchase Link</a>

-
-Dokku defaults to being installed via RPM package on CentOS 7. While certain hosts may require extra work to get running, you may optionally wish to automate the installation of Dokku without the use of our `bootstrap.sh` Bash script. The following are the steps run by said script:
-

-# Install docker
-curl -fsSL https://get.docker.com/ | sh
-
-# Install epel for nginx packages to be available
-sudo yum install -y epel-release
-

-sudo yum install -y herokuish dokku

-systemctl enable docker
-systemctl enable nginx
-```
-
-The [devicemapper](https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/) is the default Docker storage driver on CentOS 7 and defaults to a configuration mode known as `loop-lvm`. This mode is designed to work out-of-the-box with no additional configuration. However, production deployments should not run under `loop-lvm` mode. The preferred configuration for production deployments is [`direct-lvm`](https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/#/configure-direct-lvm-mode-for-production).

-# Getting Started with Dokku
-
-## What is Dokku?
-
-Dokku is an extensible, open source Platform as a Service that runs on a single server of your choice.
-
-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>
-
-Dokku is designed for usage on a fresh VM installation, and should install all necessary dependencies if installing via the bootstrap method.
-
-### Installing the latest stable version
-
-#### 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/v0.26.3/bootstrap.sh;
-sudo DOKKU_TAG=v0.26.3 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. 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
-
-```shell
-# usually your key is already available under the current user's `~/.ssh/authorized_keys` file
-cat ~/.ssh/authorized_keys | dokku ssh-keys:add admin
-
-# you can use any domain you already have access to
-dokku domains:set-global dokku.me
-```
-
-See the [user management](/docs/deployment/user-management.md#adding-ssh-keys) and [domains documentation](/docs/configuration/domains.md#customizing-hostnames) for more information.
-
-Alternatively, instructions for an unattended installation are available in the [advanced install guide](/docs/getting-started/advanced-installation.md#configuring). 
-
-#### 4. Deploy your first application
-
-At this point, you should be able to run or [deploy to the Dokku installation](/docs/deployment/application-deployment.md).
-
-### Installing via other methods
-
-For various reasons, certain hosting providers may have other steps that should be preferred to the above. If hosted on any of the following popular hosts, please follow the linked to instructions:

+    - [Ubuntu 18.04/20.04/22.04](https://www.ubuntu.com/download)
+    - [Debian 10+ x64](https://www.debian.org/distrib/)
+- 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
+    - ARMV8 (alternatively known as `arm64`), commonly used for Raspberry PI and AWS Graviton
+
+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-1-gb-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/v0.28.3/bootstrap.sh
+sudo DOKKU_TAG=v0.28.3 bash bootstrap.sh
+```
+
+The installation process takes about 5-10 minutes, depending upon internet connection speed.
+
+#### 2. Setup SSH key and Virtualhost Settings
+
+Once the installation is complete, you should configure an ssh key and set your global domain.
+
+```shell
+# usually your key is already available under the current user's `~/.ssh/authorized_keys` file
+cat ~/.ssh/authorized_keys | dokku ssh-keys:add admin
+
+# you can use any domain you already have access to
+# this domain should have an A record or CNAME pointing at your server's IP
+dokku domains:set-global dokku.me
+
+# 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
+# as you would with a regular domain name
+# this would be done by appending `.sslip.io` to your ip address
+dokku domains:set-global 10.0.0.2.sslip.io
+```
+
+See the [user management](/docs/deployment/user-management.md#adding-ssh-keys) and [domains documentation](/docs/configuration/domains.md#customizing-hostnames) for more information.
+
+#### 3. Deploy your first application
+
+At this point, you should be able to [deploy to the Dokku installation](/docs/deployment/application-deployment.md).
