For private repositories, additional registry authentication arguments are required for the `--with-registry-auth` flag to work properly with the [stack-deploy-action](https://github.com/cssnr/stack-deploy-action). The following registry configuration needs to be added: ```yaml - name: Docker Stack Deploy uses: cssnr/stack-deploy-action@v1 with: name: zenfulstats file: docker-stack.yaml host: zenful.site user: deploy ssh_key: ${{ secrets.DEPLOY_SSH_PRIVATE_KEY }} env_file: ./envfile registry_auth: true registry_host: "ghcr.io" registry_user: ${{ github.actor }} # or your specific GitHub username registry_pass: ${{ secrets.GITHUB_TOKEN }} # or ${{ secrets.USER_PAT }}
