Service elasticsearch is not visible when run tests

Question

name: Rspec
on: [push]
jobs:
  build:
    runs-on: [self-hosted, linux]
    services:
      elasticsearch:
        image: docker.         


        

Answer 1

You have to map the ports of your service containers and use localhost:host-port as address in your steps running on the GitHub Actions runner.

If you configure the job to run directly on the runner machine and your step doesn't use a container action, you must map any required Docker service container ports to the Docker host (the runner machine). You can access the service container using localhost and the mapped port.

name: Rspec
on: [push]
jobs:
  build:
    runs-on: [self-hosted, linux]
    services:
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:7.9.2
        env:
          discovery.type: single-node
        options: >-
          --health-cmd "curl http://localhost:9200/_cluster/health"
          --health-interval 10s
          --health-timeout 5s
          --health-retries 10
        ports:
        # :
        - 9200:9200
      redis:
        image: redis
        options: --entrypoint redis-server
    steps:
      - uses: actions/checkout@v2
      - name: running tests
        run: |
          sleep 60
          curl -X GET http://localhost:9200/

Alternative: Also run your job in a container. Then the job has to access the service containers by hostname.

name: Rspec
on: [push]
jobs:
  build:
    services:
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:7.9.2
        env:
          discovery.type: single-node
        options: >-
          --health-cmd "curl http://localhost:9200/_cluster/health"
          --health-interval 10s
          --health-timeout 5s
          --health-retries 10
      redis:
        image: redis
        options: --entrypoint redis-server
    # Containers must run in Linux based operating systems
    runs-on: [self-hosted, linux]
    # Docker Hub image that this job executes in, pick any image that works for you
    container: node:10.18-jessie
    steps:
      - uses: actions/checkout@v2
      - name: running tests
        run: |
          sleep 60
          curl -X GET http://elasticsearch:9200/
