* add public_ip variable, setting to 'true' allows packer to build from outside AWS * use smallest instance_type (t2.nano) and volume_size (1 GiB) * eu-west-3 region is live; ap-northeast-3 requires subscription * no longer need setup_staging_repos function... + tiny-ec2-bootstrap is available in main since v3.8 + aws-ena-driver-vanilla is only available in edge/testing * switched to linux-vanilla since linux-hardened is no longer available and linux-virt does not have NVME available + TODO? make kernel choice selectable (significant memory/disk savings linux-virt can be used)

# 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](https://github.com/mcrute/alpine-ec2-ami/blob/master/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.
|
|
|
|
- The aws-ena-driver-vanilla package is still in edge/testing. When it is
|
|
available in a release, the edge/testing repository can be removed from
|
|
/etc/apk/repositories.
|
|
|
|
- [cloud-init](https://cloudinit.readthedocs.io/en/latest/) is not currently
|
|
supported on Alpine Linux. Instead this image uses
|
|
[tiny-ec2-bootstrap](https://github.com/mcrute/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.
