   Watch out, the `depends_on` sounds like an appealing idea, but won't do it here because: _"for startup Compose does not wait until a container is “ready” (whatever that means for your particular application) - only until it’s running"_ as mentioned in the Docker documentation (https://docs.docker.com/compose/startup-order/).
   
   So the other containers will actually start as soon as `superset-init` is _started_, not once it's _done_ doing all the stuff it's made to do.
   
   Also been hitting this issue, and similarly to https://github.com/apache/superset/issues/10711 be aware initializing can just fail from time to time for reasons I do not know. The timing of the containers _might_ be the reason, and if that's the case some better coordination between `superset-init` and the other containers would then be needed (like a `wait-for-init.sh` such as the one described in the Docker docs) to actually fix the issue.

   Simply said, until the _real_ reasons are found and fixed, if you are facing this issue:
   
   1. just `CTRL+C` then remove the containers **and their volumes** with the `-v` option :
      `docker-compose -f docker-compose-non-dev.yml down -v`
      
   2. restart and enjoy:
      `docker-compose -f docker-compose-non-dev.yml down`
