GitHub Actions:Sådan oprettes forbindelse til Postgres i GithHub Actions

Jeg har en lidt anden opsætning, men dette var det mest relevante spørgsmål, da jeg stødte på den samme fejl, så ville gerne skrive her, hvis det kan hjælpe. De to ting, der var kritiske for mig, var:1) Indstil DB_HOST=localhost 2) Indstil --network="host" argument, når du starter docker-containeren med din rails-app

name: Master Build

on: [push]

env:
  registry: my_registry_name
  # Not sure these are actually being passed down to rails, set them as the default in database.yml
  DB_HOST: localhost
  DB_USERNAME: postgres
  DB_PASSWORD: postgres

jobs:
  my_image_test:
    runs-on: ubuntu-latest

    services:
      postgres:
        image: postgres:latest
        env:
          POSTGRES_DB: postgres        
          POSTGRES_PASSWORD: postgres
          POSTGRES_USER: postgres
        ports:
          - 5432:5432
        # Set health checks to wait until postgres has started
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5

    steps:
      - name: Check out repository
        uses: actions/[email protected]
      - name: Build my_image docker image
        uses: whoan/[email protected]
        with:
          username: "${{secrets.aws_ecr_access_key_id}}"
          password: "${{secrets.aws_ecr_secret_access_key}}"
          registry: "${{env.registry}}"
          image_name: my_image
          context: my_image
      - name: Lint rubocop
        working-directory: ./my_image
        run: docker run $registry/my_image bundle exec rubocop
      - name: Run rails tests
        working-directory: ./my_image
        run: docker run --network="host" $registry/my_image bash -c "RAILS_ENV=test rails db:create && RAILS_ENV=test rails db:migrate && rails test"
