Automatic deployment using Github Actions, Digital Ocean Registry into a Droplet,

Posted July 27, 2020 96 views

Hi,

I am currently woking on a workflow for my automatic deployment of dockerized application to digital ocean droplet.

Currently I am creating a docker image and pushing it to digital ocean registry using github actions.

Now I want to pull the image into my droplet from digital ocean registry and run the image.

What should be the command I should execute for this?

name: Docker

on:
  push:
    # Publish `master` as Docker `latest` image.
    branches:
      - master

    # Publish `v1.2.3` tags as releases.
    tags:
      - v*

  # Run tests for any PRs.
  pull_request:

env:
  # TODO: Change variable to your image's name.
  IMAGE_NAME: myimagename

jobs:
  # Run tests.
  # See also https://docs.docker.com/docker-hub/builds/automated-testing/
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2

      - name: Run tests
        run: |
          if [ -f docker-compose.test.yml ]; then
            docker-compose --file docker-compose.test.yml build
            docker-compose --file docker-compose.test.yml run sut
          else
            docker build . --file Dockerfile
          fi
  #Push to Digital Ocean private Registry
  pushToDORegistry:
    # Ensure test job passes before pushing image.
    needs: test

    runs-on: ubuntu-latest
    if: github.event_name == 'push' 
    steps:
      - uses: actions/checkout@v2
      - name: Build image
        run: docker build . --file Dockerfile --tag $IMAGE_NAME

      - name: Install doctl                 # install the doctl on the runner
        uses: digitalocean/action-doctl@v2
        with:
            token: ${{ secrets.DIGITALOCEAN_ACCESS_TOKEN }}

      - name: push image to digitalocean
        run: |
          doctl registry login
          docker tag $IMAGE_NAME registry.digitalocean.com/<My Registry>/$IMAGE_NAME
          docker push registry.digitalocean.com/<My Registry>/$IMAGE_NAME
  #Run the container in droplet
  deploy:
    needs: pushToDORegistry
    runs-on: ubuntu-latest
    if: github.event_name == 'push' 
    steps:
        - uses: actions/checkout@v2
        - name: Executing remote  command
          uses: appleboy/ssh-action@master
          with:
            host: ${{ secrets.HOST }}
            USERNAME: ${{ secrets.USERNAME }}
            PORT: ${{ secrets.PORT }}
            password: ${{ secrets.PASSWORD }}
            script: |
