Authenticating to docker using gcloud isn't working after this action

[atrauzzi]

TL;DR

Authenticating to docker using gcloud isn't working, despite what looks like a successful login.

Expected behavior

Docker to be successfully authenticated.

Observed behavior

Docker authentication doesn't seem to be working in combination with this actions output?

Action YAML

      - name: 'Authenticate to Google Cloud'
        uses: 'google-github-actions/auth@v0'
        with:
          credentials_json: '${{ secrets.GOOGLE_CLOUD_TOKEN }}'

      - name: 'Set up Cloud SDK'
        uses: 'google-github-actions/setup-gcloud@v0'

      - name: Docker Login
        run: "gcloud auth configure-docker --quiet us-central1-docker.pkg.dev"

      - uses: actions/checkout@v2

      - name: Build Docker Image
        run: "docker build ."

Log output

Getting:


ERROR: (gcloud.auth.docker-helper) Failed to load credential file: [/home/runner/work/api/api/39c413352e4b4825126e788d].  File /home/runner/work/api/api/39c413352e4b4825126e788d was not found.

Even though:

[sethvargo]

checkout should be the first step before doing anything else. This is documented in the readme.

If you move actions/checkout@v2 to before auth, that will fix your issue.

[atrauzzi]

Apologies, it might be worthwhile to reorganize the readme into essential sections at the top and then break out the individual flows away from that. A lot of it is all blended together, so I took a hunt-and-peck approach while reading it 🐔
