Runn Ollama via Open WebUI using Docker compose and Apache as reverse proxy for SSL

Wanted to have a quick but secure Ollama + Open WebUI setup using docker compose.

Here is a working version using Apache as a reverse proxy. The options used are pretty self-explanatory, otherwise leave a comment.

compose.yaml

services:
  ollama:
    image: ollama/ollama:latest
    ports:
      - 11434:11434
    volumes:
      - ollama:/root/.ollama
    container_name: ollama
    tty: true
    restart: unless-stopped

  open-webui:
    image: ghcr.io/open-webui/open-webui:main
    ports:
      - 3000:8080
    depends_on:
      - ollama
    environment:
      - 'OLLAMA_BASE_URL=http://ollama:11434'
      - 'WEBUI_AUTH=true'
      - 'DEFAULT_MODELS=ai/llama3.2'
      - 'WEBUI_URL=https://my.server.com'
      - 'CORS_ALLOW_ORIGIN=https://my.server.com;http://localhost:3000'
      - 'WEBUI_SESSION_COOKIE_SECURE=true'
      - 'WEBUI_AUTH_COOKIE_SECURE=true'
    extra_hosts:
      - host.docker.internal:host-gateway
    volumes:
      - open-webui:/app/backend/data
    restart: unless-stopped

volumes:
  ollama: {}
  open-webui: {}

As usual, run it via docker compose up.

That’s it.
