github action services: mysql, redis and elasticsearch

A few days ago, I needed to setup github actions for running Rails tests that required MySQL, Redis, and Elasticsearch to be installed.

Here is a is a sample configuration to boot MySQL, Redis, and elasticsearch that can be accessed from 127.0.0.1 address.

    services:
      mysql:
        image: mysql:8.0
        ports:
          - 3306:3306
        env:
          MYSQL_DATABASE: sample_database_test
          MYSQL_ROOT_PASSWORD: root
        options: >-
          --health-cmd "mysqladmin ping"
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5
      redis:
        image: redis
        ports:
          - 6379:6379
        # Set health checks to wait until redis has started
        options: >-
          --health-cmd "redis-cli ping"
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:8.13.0
        ports:
          - 9200:9200
        options: --health-cmd="curl http://localhost:9200/_cluster/health" -e "discovery.type=single-node" -e "xpack.security.enabled=false"
