Github Action to deploy Docker Image from Github Packages

Question

I am coming from Heroku and want to get used to Docker and learn more about DevOps. So I informed myself about Github Actions and Github Packages.

Now I am searching for a starting point for my problem as I want to deploy via commit to a Digital Ocean Dropplet.

I have found the doctl lib. and some another question which unfortunately is using digital ocean registry.

If someone could share the actions.yml file for me, this would help me a lot.

Thanks

I successfully pushed my image to Github Container Registry with the following workflow name: GHCR-DigitalOcean on: # Trigger the workflow on push push: branches: - main jobs: push_to_registry: name: Push to GHCR -> DigitlOcean runs-on: ubuntu-latest steps: # Checkout the Repository - name: Checking out the repository uses: actions/checkout@v2 # Setting up Docker Builder - name: Set up Docker Builder uses: docker/setup-buildx-action@v1 # Set Github Access Token with "write:packages" scope for Github Container Registry. # Then go to repository setings and add the copied token as a secret called "CR_PAT" # https://github.com/settings/tokens/new?scopes=repo,write:packages&description=Github+Container+Registry - name: Log into GitHub Container Registry uses: docker/login-action@v1 with: registry: ghcr.io username: ${{ github.repository_owner }} password: ${{ secrets.CR_PAT }} # Push to Github Container Registry - name: Push to Github Container Registry uses: docker/build-push-action@v2 with: context: . version: latest file: dockerfile push: true tags: ghcr.io/${{ github.repository }}:latest

Unfortunately I got stuck by the ssh handshake as I try to provide the credentials instead of a key. 2020/12/*** 13:30:13 ssh: handshake failed: ssh: unable to authenticate, attempted methods [none password], no supported methods remain deploy_to_digital_ocean_dropplet: name: Deploy to Digital Ocean Droplet runs-on: ubuntu-latest needs: push_to_github_container_registry steps: - name: Deploy to Digital Ocean droplet via SSH action uses: appleboy/ssh-action@v0.1.3 with: HOST: ${{ secrets.HOST }} USERNAME: ${{ secrets.USERNAME }} PASSWORD: ${{ secrets.PASSWORD }} PORT: ${{ secrets.PORT }} script: | # Stop running container docker stop ${{ github.repository_owner }} # Remove old container docker rm ${{ github.repository_owner }} # Login to Github Container Registry docker login https://ghcr.io -u ${{ github.repository_owner }} -p ${{ secrets.CR_PAT }} # Pull the Docker Image docker pull ghcr.io/${{ github.repository }}:latest # Run a new container from a new image docker run -d \ --restart always \ --env-file .env \ -p 8000:8080 \ --name $(echo $${{ github.repository }})
