Added docker setup for better compatibility

[animalite]

— Easy environment management
— Adds compatibility with Intel Macs
— Added setup function to devsetup.sh —> dockerized()
— Updated local_settings.py.example to include actual useful values. (ports)

I wanted to setup the dev environment and was impossible to do in my machine because of Torch incompatibilities. Now I can set it up reliably. However, building the image takes a long time, but it's the only option for me.

Hey, thanks for creating this PR and figuring out all the details! Seems very useful. A couple of thoughts:

• It might be nice to split up the Django app and the frontend into separate containers and to add them to the existing compose-dev.yaml, instead of creating a new docker-compose.yml.
• For installing pnpm, I recommend using corepack, which is built-in to Node.js. TL;DR: Run corepack enable after installing Node.js.
• For installing uv, the authors recommend using a COPY --from in the Dockerfile (see the docs).
• There seems to be quite a bit of code duplication between the Dockerfile and devsetup.sh. Maybe we can bring them a little closer together?

Thanks again, looking forward to merging this.

Is skipping checks required, i.e. are they failing in Docker?

[animalite]

It's not necessary. I was just following the Readme and current code. Will be removed.

[animalite]

After some checks, yes, it is necessary since the db is empty and django checks for tables that don't exist yet. I'll put it back.

[animalite]

I didn't change the current compose-dev.yaml so not to give a surprise to other devs that use a venv with suddenly a 14GB build... Also, it follows the standard (docker compose up).

[animalite]

Seems to be working fine now. Should the README be updated as well?

[krmax44]

Sorry for the delay! I'm thinking about how we can integrate this with well froide, i.e. by having froide base images that we can pick up in this project. Your PR is a great starting point for this, so thanks again! Since we're not using Docker outside of running Postgres + ElasticSearch during development, this doesn't have super high priority right now. But it might be handy for use in CI as well, see okfde/froide#1237.
