Last time i did look into docker it couldn't even tell if a service is up or still starting and there were all kinds of weird hacks around that like "is something listening on the configured port". Did that improve?
Maybe it already has something like this, but I feel like systemd could provide an API endpoint for applications to send a simple status when they are "ready" - at which point it would be up to the developers to provide that at the right time.

Perfect. Thank you!
