Add devcontainer

[dbrgn]

This adds a devcontainer for working on this project.

Includes:

• PostgreSQL server running locally in container
• OpenCode
• Non-root user and isolation options to ensure strict sandboxing

To do:

• Port 3000 is forwarded, but when I access it I get redirected to https. Why?
• Cache ruby gems on rebuild
• Cache Postgres database on rebuild

@rnestler do you want to give it a try? In VS Code (the version from Microsoft, unfortunately not Code OSS) you can open the project, then it asks you whether you want to reopen the project in the dev container. Alternatively, press Ctrl+Shift+P and type "reopen in dev".

Sounds like the app runs in production instead of development mode/config.

Haha, it was a different project: The gfroerli-api Docker container was already running and blocking port 3000, thus VSCode exposed it on port 3001 :D

Do I need some kind of plugin? I installed visual-studio-code-bin-1.107.1-1 from the AUR.

I installed the "Dev containers" extension, but now I'm greeted with

Since adding a user to the docker group is basically giving root permissions without any password I'm not sure I like this...

Yes, you need the extension.

That's your choice, I generally allow it on my development machines. You could also try whether rootless podman works, but that has its own quirks.

I didn't test it, but I guess you can just merge it if it works for you 👍
