quipper/actions-runner

This is a container image extending actions/runner.

For maintainability and security,

• Align to the official image
• Keep the script simple
• Do not add extra packages

Features

We extend the official image for the following issues:

• Run both runner and Dockerd in same container for the resource efficiency of Kubernetes nodes. This image starts Dockerd under docker-init.
• Add some essential packages such as git
• Support Ubuntu 20.04 runner for backward compatibility
• Run a job on both amd64 and arm64 nodes. This repository provides a multi-architectures image. (community#56720) (resolved by actions/runner#2601)
• Support ruby/setup-ruby which does not support Debian. This image is based on Ubuntu. (actions-runner-controller#2610) (resolved by actions/runner#2651)
• Add a hosted tool cache for actions/setup-node (#160) (resolved by actions/setup-node#857)
• Automatically set the cloud-local APT sources to reduce time of apt-get (#432)

We are looking for the official supports, but need to maintain our custom image for now.

Release

When a new version of actions/runner is released,

1. Renovate creates a pull request to update a dependency
2. Renovate automatically merges it
3. GitHub Actions automatically creates a release corresponding to the runner version

Here is the versioning policy.

• Use same version as the upstream, such as 2.304.0
• If we have added a change, increment the patch version. For example, if the upstream is 2.304.0, we will create 2.304.1
