How can I set up CI with Docker Compose?

To set up CI with Docker Compose, you can use a CI tool like GitHub Actions or GitLab CI. Do you have a specific CI tool in mind?

I'm using GitHub Actions. Can you provide a sample workflow?

Sure! Here's a basic example of a GitHub Actions workflow that builds and tests your Docker Compose setup:

name: CI

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    services:
      db:
        image: postgres
        env:
          POSTGRES_USER: user
          POSTGRES_PASSWORD: password
        ports:
          - 5432:5432
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v1
      - name: Build and test
        run: |
          docker-compose up --build -d
          docker-compose exec app npm test

What if I need to run migrations before tests?

You can add a step to run migrations before executing your tests. Modify the workflow like this:

      - name: Run migrations
        run: |
          docker-compose exec app npm run migrate

Thanks! This is really helpful.
