action-common-setup

A little composite action to consistently setup GitHub Actions across my homelab runner environments.

• If the ssh-agent bin exists
  • Starts a fresh ssh-agent
  • Sets the env vars for future steps
• Installs the step binary for step-ca commands
• Bootstraps the environment for the Homelab SPM CA Trust
  • Tries to update any CA certs for the system that were missed.
  • Configures git commands for https://git.auengun.net to use the Root CA for trust.
• If JWK_PASSWORD is defined:
  • Attempts to provision a ssh user certificate for the ${{ github.actor }} (username of the user that triggered the initial workflow run) for clone/inter-node actions.
  • Runs step ssh config to update known hosts and other params for easier ssh commands.
• Clones the repo's code into the /workspace using https://code.forgejo.org/actions/checkout
