ported from: https://github.com/shivaraj-bh/ollama-flake/blob/main/services/open-webui.nix

This was also recently upstreamed to nixpkgs: NixOS/nixpkgs#316248

TODO:

• Document how to use it with ollama service
• Use open-browser process in example and documentation

I get the following on mac:

       error: The option `perSystem.aarch64-darwin.process-compose.default.services.open-webui' does not exist. Definition values:

Ah sorry (I was just checking with just ex-llm in devShell), this should work:

 nix run "github:juspay/services-flake/open-webui?dir=example/llm" --refresh --override-input services-flake github:juspay/services-flake/open-webui

The processes are running in two different namespaces (default and ollama1) ... shouldn't they be under the same namespace?

In our current design, every service belongs to its own namespace. We could manually modify this, if that’s what we desire here.

Fantastic, worked on mac!

I don't remember what we do. But this doesn't seem to be the case for the llm example because only the ollama1 service is running in its own namespace (ollama1). Not the open-webui1 service, as it is running in the default namespace.

Fixed it in the recent commit

Re-ran nix run and everything still works (re-using the already downloaded models). This will be a cool video demo (especially if it finishes with writing prompts in the browser app).

LGTM, once the hardcoded strings in the docs are addressed.

Thanks for all the feedback @srid and @drupol! ❤️
