GitHub

A collection of tasks to help working with the GitHub API.

GitHub token

Most tasks would expect to have a secret set in the kubernetes secret github-secret with a GitHub token in the key token, you can easily create it on the command line with kubectl like this :

kubectl create secret generic github --from-literal token="MY_TOKEN"

Set Status on a Commit/PR

The github-set-status task allows external services to mark GtiHUB commits with an error, failure, pending, or success state, which is then reflected in pull requests involving those commits.

Statuses include as well a description and a target_url, to give the user informations about the CI statuses or a direct link to the full log.

kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/github/set_status.yaml

• GITHUB_HOST_URL:: The GitHub host domain default: api.github.com
• SHA:: The commit SHA to set the status for e.g: tektoncd/catalog
• TARGET_URL:: The target URL to associate with this status. This URL will be linked from the GitHub UI to allow users to easily see the source of the status. For example you can link to a dashboard URL so users can follow a Pipeline/Task run.

          The cat went here and there
          And the moon spun round like a top,
          And the nearest kin of the moon,
          The creeping cat, looked up.
          Black Minnaloushe stared at the moon,
          For, wander and wail as he would,
          The pure cold light in the sky
          Troubled his animal blood.
