github-runner-REPO-arm64-rpi4-deployment,yml

# Before applying this k8s deployment is necessary to adjust the labels specified in the
# selctor to match the ones in use in your kubernetes cluster.
# It is in addition necessary to replace the __ACCESS_TOKEN__, __REPO_URL__, __REPO_NAME__
# placeholders, the gitlab runner are per repo or per organization, they can't be assigned
# directly to an user.
