Readme

open-webui

Open WebUI — a feature-rich, self-hosted ChatGPT-style interface for local LLMs via Ollama (and any OpenAI-compatible API): multi-model chats, RAG over your documents, prompts, and user management. Host-networked Nomad service with a persistent volume. Pairs with the ollama pack.

Usage

nomad-pack registry add nomploy github.com/Nomploy/nomad-packs
nomad-pack run open-webui --registry nomploy

In nomploy: create a Compose service, type Nomad Pack, pack open-webui, custom registry github.com/Nomploy/nomad-packs, then Deploy. Open http://<node-ip>:3008 and create the admin account (the first user is the admin).

Run the ollama pack alongside it (and ollama pull <model>), so there's a model to chat with. By default Open WebUI talks to Ollama at http://127.0.0.1:11434 (same node).
