Trying to run two processes in a single Docker container on Cloud Run (Apache 2 and Datasette, to explore some reported bugs with mod_proxy) - urgh, this is so hard!

Found several recipes that work on my laptop but fail when I deploy them to Cloud Run github.com/simonw/dataset…

I'd love to figure this out because running two processes in the same container feels like a really useful trick to have in my pocket, but I may have to give up and run two separate containers instead - annoying when I'm just trying to provide a tiny interactive demo

I did get a new TIL out of this exercise - I figured out how to use the equivalent of "docker build --build-arg" with Google Cloud Build (you have to generate a cloudbuild.yml file and pass it to "gcloud builds submit --config") til.simonwillison.net/cloudrun/using…

Now wondering if the problem might be that Cloud Run restricts CPU between requests, which might be causing some havoc with my separate background process

Ended up deploying my demo to @flydotio instead - datasette-apache-proxy-demo.fly.dev/prefix/ is now live, demonstrating Datasette running behind an Apache 2 proxy (on port 80) that passes /prefix/ through to Datasette (private port 8001)

Dockerfile and fly.toml are here: github.com/simonw/dataset…
