Alpine Linux EC2 AMI Build

NOTE: This is not an official Amazon or AWS provided image. This is community built and supported.

This repository contains a packer file and a script to create an EC2 AMI containing Alpine Linux. The AMI is designed to work with most EC2 features such as Elastic Network Adapters and NVME EBS volumes by default. If anything is missing please report a bug.

This image can be launched on any modern instance type. Including T2, M5, C5, I3, R4, P2, P3, X1, X1e, D2. Other instances may also work but have not been tested. If you find an issue with instance support for any current generation instance please file a bug against this project.

To get started use one of the AMIs below. The default user is alpine and will be configured to use whatever SSH keys you chose when you launched the image. If user data is specified it must be a shell script that begins with #!. If a script is provided it will be executed as root after the network is configured.

Note: This image will be updated as Alpine Linux changes over time and as AWS adds regions. This file and releases.yaml will be updated as new regions are made available.

Caveats

This image is being used in production but it's still somewhat early stage in its development and thus there are some sharp edges.

Only EBS-backed HVM instances are supported. While paravirtualized instances are still available from AWS they are not supported on any of the newer hardware so it seems unlikely that they will be supported going forward. Thus this project does not support them.
Not all packages required have been merged into the upstream aports tree. When they are they will still only be available on edge. Until then the image sources a few packages from a testing repo managed by the owner of this repository. The builds in this repository should be identical to what is eventually merged into the official tree.
cloud-init is not currently supported on Alpine Linux. Instead this image uses tiny-ec2-bootstrap. Hostname setting will work as will setting the ssh keys for the Alpine user based on what was configured during instance launch. User data is supported as long as it's a shell script (starts with #!). See the tiny-ec2-bootstrap README for more details. You can still install cloud-init using aports but the version in the tree is somewhat old and may not work correctly for Alpine. If full cloud-init support is important to you please file a bug against this project.
CloudFormation support is still forthcoming. This requires patches and packaging for the upstream cfn tools that have not yet been accepted. Eventually full CloudFormation support will be available.
