But after that first load, I didn't get the issue again. It would re-occur if the service started from cold boot. \r\n\r\nI suspect this is a race condition in the supervisord configuration. The errors I got were the same `Connection refused: AH00957: http: attempt to connect to 127.0.0.1:8001 (127.0.0.1) failed`, and that seems to indicate that `datasette` hadn't yet started. \r\n\r\nLooking at the order of logs getting back, the processes reported successfully completing loading after the first 503 was returned, so that makes me think race condition. \r\n\r\nI can replicate this locally, if I `docker run` and request `localhost:5000/prefix` _before_ I get the `datasette entered RUNNING state` message. Cloud Run wakes up when requests are received, so this test would semi-replicate that, but local docker would be the equivalent of a persistent process, hence it doesn't normally exhibit the same issues.\r\n\r\nUnfortunately supervisor/supervisor issue 122 (not linking as to prevent cross-project link spam) seems to say that dependency chaining is a feature that's been asked for for a long time, but hasn't been implemented. You could try some suggestions in that thread.
