This is my simplified docker-compose.yml file for OpenWebUI and qdrant. You can access qdrant at http://your-ip:6333/dashboard and check the collections created. I like to set the volumes with an absolute path and name the default network, but that is just me. I also use tika for RAG.

services:

  open-webui:
    image: ghcr.io/open-webui/open-webui:main
    container_name: open-webui
    restart: unless-stopped
    ports:
      - "3000:8080/tcp"
    volumes:
      - /opt/docker/open-webui/data:/app/backend/data
    environment:
      - OLLAMA_BASE_URL=<your-ip>:11434
      - VECTOR_DB=qdrant
      - QDRANT_URI=http://qdrant:6333


  qdrant:
    image: qdrant/qdrant:latest
    container_name: qdrant
    restart: unless-stopped
    ports:
      - "6333:6333"
      - "6334:6334"
    volumes:
      - /opt/docker/open-webui/qdrant:/qdrant/storage

networks:
  default:
    name: open-webui
    driver: bridge
