Documented steps

  1. Use the short-form list syntax: `depends_on: [db, redis]` on a service to make Compose start `db` and `redis` before it.
  2. Short syntax behaves like `condition: service_started` for each dependency.
  3. Example: app: { depends_on: [db] } starts db before app.
  4. Official docs: https://docs.docker.com/compose/how-tos/depends_on/ and https://docs.docker.com/reference/compose-file/services/#depends_on
