   The ordering is technically fine (depends_on field in the compose file manages the ordering). The problem is, each container has a bootstrap process that takes some time to complete (e.g. mysql), so just because it has started it doesn't mean it's ready. In this case devlake is trying to talk to mysql before it is fully ready, and that throws an error.
   
   With docker-compose v2 one would define healthchecks in the compose file and have the containers wait using conditions until their dependencies are healthy before boostrapping. v3 removed this feature as far as I am aware.
   
   So our options are:
   1. Use the v2 docker-compose spec, and use healthchecks and conditions in the compose file
   2. Enhance the devlake service logic to retry DB connectivity for a while
   3. Apparently the more recent compose versions allow backwards portability as far as support for conditions go [see this discussion](https://github.com/peter-evans/docker-compose-healthcheck/issues/3). Maybe investigate this and see if it'll work.
