Tailscale GitHub Action with ACL Labels Support

An manual-written fork of https://github.com/tailscale/github-action, with support for ACL tags. Currently only available on Linux, but PRs are generally welcome. :)

Usage

    - name: Setup Wireguard VPN through Tailscale
      # or use main branch to go on the bleeding edge
      uses: MadeByThePinsHub/[email protected]
      with:
        # secret name may varies on your org
        authkey: ${{ secrets.TAILSCALE_RECAPTIMEBOT_CICD_KEY }}
        # the defaults tag goes here, plus some addons.
        labels: tag:gh-actions,tag:linux,tag:msft-azure,tag:ssh,tag:docker
        # Going to unstable is risky, beware!
        version: "1.17.91"

Supported Configuration

• authkey: The Tailscale pre-auth key, usually an ephemeral authkey, to ensure your tailnet's machines' list don't clutter.
• labels: ACL labels for your tailnet admins' rules, defaults to our configuration tag:gh-actions,tag:linux,tag:msft-azure, where:
  • tag:gh-actions is an GitHub Actions runner, either hosted by M$FT/GitHub or self-hosted.
  • tag:linux is our meta-label for Linux machines, not required to add per-distro labels.
  • tag:msft-axure is our another meta-labels for VMs managed on Azure.
• version: Use this to install Tailscale from unstable track (tl;dr the minor version shouldn't be divisible by 2), check https://pkgs.tailscale.com/unstable/ for latest unstable version.

Troubleeshooting and Notes

• Remember NOT to enable manual approval on newer devices, since this will make execution time longer + may hit the hard timeout limit of 30 days in GitHub if left alone.
• The default labels assumes they have atleast one tagOwner on your tailnet's ACL policy. If not, they would consider as invalid tags so add these JSON code from our ACL config below. Make sure to customize these before hitting Save!

  "tagOwners": {
    "tag:linux": [
      "group:admins",
      "group:squad",
      "group:bots"
    ],
    "tag:gh-actions": [
      "group:bots"
    ],
    "tag:msft-azure": [
      "group:admins",
      "group:squad",
      "group:bots"
    ],
    "tag:docker": [
      "group:admins",
      "group:squad",
      "group:bots"
    ]
  }

Maintainer Notes

The GitHub Actions workflow for testing the workflow if works uses @ajhalili2006's ephemeral pre-auth keys for testing on his personal tailnet.
