use OLLAMA_HOST when connecting?

[mhdawson]

I'm wondering if its been discussed if using OLLAMA_HOST on the client side makes sense.

There have been a number of instances where I've had to figure out how to pass through the server IP for my remote system running ollama in libraries that use ollama-js under the covers. For example - i-am-bee/bee-agent-framework#83

In this cases it would be easier if we could specify OLLAMA_HOST or something only used at the client like OLLAMA_SERVER without having to figure out how to get it down to the client through the libraries APIs.

It that makes sense I'd be happy to investigate and open a PR but I want to make sure it's something that would be acceptable before investing the time to do that.

I'll add that even on the same host I had an issue where I had set OLLAMA_HOST to something that did not include localhost (ie not 0.0.0.0) and then had to pass in the host even though I was running on the same machine. In that case have the client support OLLAMA_HOST would have made it more straight forward.

Where do you specify the host on client side? I am trying to use an OpenWebUI instance on a remote server which seems to be impossible.

@nise Ollama uses an OLLAMA_HOST environment variable. Depending on your scenario, try something like this:

import { Ollama } from 'ollama'

const ollama = new Ollama({ 
  host: process.env.OLLAMA_HOST || 'http://127.0.0.1:11434'
})

const response = await ollama.chat({
  model: 'llama3.1',
  messages: [{ role: 'user', content: 'Why is the sky blue?' }],
})
