Depending on which web framework you’re using, there might be better options than exactly reproducing the Toolforge environment. (Unless you’re debugging issues specific to that environment, I suppose.) For instance, Flask has a development mode which automatically reloads source files as soon as they change on disk, and offers you an in-browser debugger when an error occurs. It’s amazing, I can’t recommend it enough.

I've found it very useful with php tools to use the instructions here:

https://wikitech.wikimedia.org/wiki/Help:Toolforge/Kubernetes#PHP

where it says "You may run the container on your local computer (not on Toolforge servers) by executing a command like this: ..."

which allows testing changes locally in a nice way before deploying them.

However there doesn't seem to be anything equivalent for the python images - I can see what's available here:

https://wikitech.wikimedia.org/wiki/Help:Toolforge/Web#Python_(uWSGI)

and I can see I should use the image
docker-registry.tools.wmflabs.org/toolforge-python37-web
(by the way, docker-registry.toolforge.org does NOT work right now when fetching images!)

but I can't figure out how to tell the image where to find the python app in the docker start command. Any hints out there?
