depends_on:
depends_on does not wait for db and redis to be “ready” before starting web - only until they have been started. If you need to wait for a service to be ready, see Controlling startup order for more on this problem and strategies for solving it.
Version 3 no longer supports the condition form of depends_on.
- The depends_on option is ignored when deploying a stack in swarm mode with a version 3 Compose file.
