4. Create GitHub Actions Workflow

Create .github/workflows/deploy.yml in your repo:

name: Deploy to QA

on:
  push:
    branches:
      - master  # Runs on direct push to 'qa'

jobs:
  deploy:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout Code
        uses: actions/checkout@v3

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2

      - name: Log in to Docker Hub
        uses: docker/login-action@v2
        with:
          username: ${{ secrets.DOCKER_USERNAME }}
          password: ${{ secrets.DOCKER_PASSWORD }}

      - name: Build and Push Docker Image
        run: |
          docker build -t dockerusername/myapp:${{ github.sha }} .
          docker push dockerusername/myapp:${{ github.sha }}

      - name: Deploy to Server
        uses: appleboy/ssh-action@v0.1.10
        with:
          host: ${{ secrets.SERVER_HOST }}
          username: ubuntu
          key: ${{ secrets.SSH_PRIVATE_KEY }}
          port: 22
          script: |
            docker pull dockerusername/myapp:${{ github.sha }}
            docker ps -a  # Debugging step to check existing containers
            docker stop myapp || true
            docker rm -f myapp || true
            docker run -d -p 3000:3000 --restart unless-stopped --name myapp dockerusername/myapp:${{ github.sha }}
            docker image prune -f

1. myapp - docker image name
2. create account on dockerhub

• this process will login to docker hub , build your image and pull that image to your server
