Docker Github Actions Runner

Docker Pulls awesome-runners

This will run the new self-hosted github actions runners.

Quick-Start (Examples and Usage)

Please see the wiki

Notes

Security

It is known that currently tokens (ACCESS_TOKEN / RUNNER_TOKEN ) are not safe from exfiltration. If you are using this runner make sure that any workflow changes are gated by a verification process (in the actions settings) so that malicious PR's cannot exfiltrate these.

Docker Support

Please note that while this runner installs and allows docker, github actions itself does not support using docker from a self hosted runner yet. For more information:

Also, some GitHub Actions Workflow features, like Job Services, won't be usable and will result in an error.

Containerd Support

Currently runners do not support containerd

Docker-Compose on ARM

Please note docker-compose does not currently work on ARM (see issue) so it is not installed on ARM based builds here. A workaround exists, please see here

Docker Artifacts

Container Base Supported Architectures Tag Regex Docker Tags Description Notes
ubuntu focal x86_64,arm64 /\d\.\d{3}\.\d+/ /\d\.\d{3}\.\d+-ubuntu-focal/ latest ubuntu-focal This is the latest build (Rebuilt nightly and on master merges). Tags without an OS name are included. Tags with -ubuntu-focal are included and created on upstream tags.
ubuntu jammy x86_64,arm64 /\d\.\d{3}\.\d+-ubuntu-jammy/ ubuntu-jammy This is the latest build from jammy (Rebuilt nightly and on master merges). Tags with -ubuntu-jammy are included and created on upstream tags. There is currently an issue with jammy from inside a 20.04LTS host which is why this is not latest
ubuntu bionic x86_64,arm64 /\d\.\d{3}\.\d+-ubuntu-bionic/ ubuntu-bionic This is the latest build from bionic (Rebuilt nightly and on master merges). Tags with -ubuntu-bionic are included and created on upstream tags.
debian buster (now deprecated) x86_64,arm64 /\d\.\d{3}\.\d+-debian-buster/ debian-buster Debian buster is now deprecated. The packages for arm v7 are in flux and are wildly causing build failures (git as well as apt-key and liblttng-ust#. Tags with -debian-buster are included and created on upstream tags.
debian bullseye x86_64,arm64 /\d\.\d{3}\.\d+-debian-bullseye/ debian-bullseye This is the latest build from bullseye (Rebuilt nightly and on master merges). Tags with -debian-bullseye are included and created on upstream tags.
debian sid x86_64,arm64 /\d\.\d{3}\.\d+-debian-sid/ debian-sid This is the latest build from sid (Rebuilt nightly and on master merges). Tags with -debian-sid are included and created on upstream tags.

These containers are built via Github actions that copy the dockerfile, changing the FROM and building to provide simplicity.

Environment Variables

Environment Variable Description
RUNNER_NAME The name of the runner to use. Supercedes (overrides) RUNNER_NAME_PREFIX
RUNNER_NAME_PREFIX A prefix for a randomly generated name (followed by a random 13 digit string). You must not also provide RUNNER_NAME. Defaults to github-runner
ACCESS_TOKEN A github PAT to use to generate RUNNER_TOKEN dynamically at container start. Not using this requires a valid RUNNER_TOKEN
RUNNER_SCOPE The scope the runner will be registered on. Valid values are repo, org and ent. For 'org' and 'enterprise', ACCESS_TOKEN is required and REPO_URL is unneccesary. If 'org', requires ORG_NAME; if 'enterprise', requires ENTERPRISE_NAME. Default is 'repo'.
ORG_NAME The organization name for the runner to register under. Requires RUNNER_SCOPE to be 'org'. No default value.
ENTERPRISE_NAME The enterprise name for the runner to register under. Requires RUNNER_SCOPE to be 'enterprise'. No default value.
LABELS A comma separated string to indicate the labels. Default is 'default'
REPO_URL If using a non-organization runner this is the full repository url to register under such as 'https://github.com/myoung34/repo'
RUNNER_TOKEN If not using a PAT for ACCESS_TOKEN this will be the runner token provided by the Add Runner UI (a manual process). Note: This token is short lived and will change frequently. ACCESS_TOKEN is likely preferred.
RUNNER_WORKDIR The working directory for the runner. Runners on the same host should not share this directory. Default is '/_work'. This must match the source path for the bind-mounted volume at RUNNER_WORKDIR, in order for container actions to access files.
RUNNER_GROUP Name of the runner group to add this runner to (defaults to the default runner group)
GITHUB_HOST Optional URL of the Github Enterprise server e.g github.mycompany.com. Defaults to github.com.
DISABLE_AUTOMATIC_DEREGISTRATION Optional flag to disable signal catching for deregistration. Default is false. Any value other than exactly false is considered true. See here
CONFIGURED_ACTIONS_RUNNER_FILES_DIR Path to use for runner data. It allows avoiding reregistration each the start of the runner. No default value.
EPHEMERAL Optional flag to configure runner with --ephemeral option. Ephemeral runners are suitable for autoscaling.
DISABLE_AUTO_UPDATE Optional environment variable to disable auto updates. Auto updates are enabled by default to preserve past behavior. Any value is considered truthy and will disable them.
