services:
  redis:
    # image has to be in the canonical format, i.e., an image called `redis` is actually docker.io/library/redis
    image: docker.io/library/redis:6.0.20
    # ports is a usual mapping like in docker compose, notice that depending on the env it will be mapped on the localhost
    # or on whatever host is running the docker (like host `docker` in gitlab) so we don't bind the ports on 127.0.0.1
    # if you're really concerned about security, an option would be to define a MAYBE_BIND_PORT in each of the env vars files as:
    # default.env: `MAYBE_BIND_PORT=127.0.0.1:` (ending with a colon)
    # gitlab.env: `MAYBE_BIND_PORT=` [empty]
    # and then bind ports as: `- ${MAYBE_BIND_PORTS}6379:6379`
    ports:
      - 6379:6379
    # ignore_logs can be used to surpress the logs of some chatty containers
    # you can still read them after the test has finished by running `docker logs redis`
