I tried deploying the most recent version of the Dockerfile in this thread (link to comment), and after trying a few different different combinations, I was only successful when I used --no-cpu-throttling ("CPU Is always allocated" in the UI)

Using this method, I got a very similar issue to you: The first time I'd load the site I'd get a 503. But after that first load, I didn't get the issue again. It would re-occur if the service started from cold boot.

I 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.

Looking 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.

I 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.

Unfortunately 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.

Would it make sense to run datasette with a fswatch/inotifywait on a folder, then?

It looks like if the files argument is a directory, config_dir is set, but files in that folder are only loaded into self.files at the Datasette class initialisation.

I tried seeing if I could get --reload to work, but I'm getting issues trying to use that command when specifying a directory, as the command serve ends up in the files list(?):

datasette serve . --reload Error: Invalid value for '[FILES]...': Path 'serve' does not exist.

I am also getting this issue, using the currently most recent version of datasette

$ datasette --version datasette, version 0.59.1

If I run datasette within just a folder of files,

$ datasette serve .

Adding new files while datasette is running shows no new files, and removing files causes datasette to return 500 errors.
