Sure, I run OpenWebUI in a docker container from my TrueNAS SCALE home server (it's one of their standard packages, so basically a 1-click install). From there I've configured API use with OpenAI, Gemini, Anthropic and DeepSeek (part of my job involves evaluating the performance of these big models for various in-house tasks), along with pipelines for some of our specific workflows and MCP via mcpo.
I previously had my ollama installation in another docker container but didn't like having a big GPU in my NAS box, so I moved it to its own box. I am mostly interested in testing small/tiny models there. I again have Ollama running in a Docker container (just the official Docker image), but this time on a Debian bare-metal server, and I configured another OpenWebUI pipeline to point to that (OpenWebUI lets you select which LLM(s) you want to use on a conversation-by-conversation basis, so there's no problem having a bunch of them hooked up at the same time).
