- Get the build system container running on the kluster, see if you can use the actions/actions-runner-controller: Kubernetes controller for GitHub Actions self-hosted runners
- Lets do it vanilla first (running build system container)
- Create the image using base image: Package actions-runner (github.com)
- TODO: push the docker image to a registry so anyone can pull it
Dockerfile (Here temporarily, these are the only 2 files you need to get this to work)

- do 'docker image ls' to ensure its there
- Then you must be an organization administrator, and make a personal access token with the "admin:org" and "repo" scope to create a registration token for an organization (REST API endpoints for self-hosted runners - GitHub Docs)
- Copy the token, and use it in the next step
Run the docker image
Code Block |
---|
docker run \
--env ORGANIZATION=<ORG> \
--env ACCESS_TOKEN=<PERSONAL-TOKEN> \
--name runner1 \
runner-image |
Replace <ORG> with the organization name
Replace <PERSONAL-TOKEN> with the token you created above
- And now your runner should be registered and running
- When done testing make sure to 'ctrl+c' and 'stop' and 'remove' the container
- Start the image using kubectl for our ad-build kubernetes cluster you created above
- For now, use a local registry
- kubectl create deployment runner1 --image=runner-image
- Then we can use that for building buildroot. One of the workflows will be it checking out on /scratch/ in s3df, then build, and output results there.
