I am trying to use tailscale/github-action@v2 Github action. You can find my Github action code below

name: tailscale test

on:
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2

      - name: Tailscale
        uses: tailscale/github-action@v2
        with:
          authkey: ${{ secrets.TAILSCALE_AUTHKEY }}
          args: --reset --accept-routes --exit-node nas1
          hostname: github-action-${{ github.run_id }}

However, when running above action, I am getting error invalid value "nas1" for --exit-node; must be IP or unique node name

I can successfully run Tailscale using nas1 as exit node when using Tailscale CLI

sudo tailscale up --authkey "${{ secrets.TAILSCALE_AUTHKEY }}" --hostname "github-action-${{ github.run_id }}"
sudo tailscale up --reset --accept-routes --exit-node "nas1" --hostname "github-action-${{ github.run_id }}"

Could you guide me on how to debug this issue, please?

I ran into this as well, no matter what I do I cannot get the action to come up and assign an exit node so I broke it up into two different actions in the yaml file.

Would be interesting to know if this is by-design and if so, could it be documented?

    - name: Tailscale
      uses: tailscale/github-action@v2
      with:
        oauth-client-id: ${{ secrets.TS_OAUTH_CLIENTID }}
        oauth-secret: ${{ secrets.TS_OAUTH_KEY }}
        tags: tag:ci
        #args: "--exit-node=nas1" #using this we get an error: must be IP or unique node name
    - name: Tailscale - ReRun Up Command To Set ExitNode to pfsense
      uses: tailscale/github-action@v2
      with:
        oauth-client-id: ${{ secrets.TS_OAUTH_CLIENTID }}
        oauth-secret: ${{ secrets.TS_OAUTH_KEY  }}
        tags: tag:ci
        args: "--exit-node=nas1"

FYI I found the reference issue explaining why this happens (again, I really think this needs to be documented somehow in the github action itself as it seems like anyone wanting to use this action would probably have to deal with the problem).

FYI you can just run an additional tailscale set command:

- name: tailscale connect
      uses: tailscale/github-action@v2
      with:
        oauth-client-id: ...
        oauth-secret: ...
        tags: ...
    - name: use named exit node in tailscale
      run: |
        timeout 5m sudo -E tailscale set --exit-node=<name>
