Describe the feature you'd like

The downloaded model can be saved in a fixed location to avoid re-downloading each time Docker is restarted.

And the following models will be downloaded if you select them in the RAGFlow UI.
- BAAI/bge-base-en-v1.5
- BAAI/bge-large-en-v1.5
- BAAI/bge-small-en-v1.5

Not container restart but recreation redownload models.
To avoid redownload, you can change docker-compose.yml to mount a host directory into ragflow container's /root/.ragflow directory.

[biofer]

As per the previous response, I have modified the docker-compose.yml file to map the host directory to the container's /root/.ragflow directory to avoid re-downloading models on container restart. My updated configuration is as follows:

volumes:
  - ./service_conf.yaml:/ragflow/conf/service_conf.yaml
  - ./ragflow-logs:/ragflow/logs
  - ./nginx/ragflow.conf:/etc/nginx/conf.d/ragflow.conf
  - ./nginx/proxy.conf:/etc/nginx/proxy.conf
  - ./nginx/nginx.conf:/etc/nginx/nginx.conf
  - ../model:/root/.ragflow

After starting the container, the model files are successfully created inside the container in the `/root/.ragflow` directory. However, the corresponding host directory `../model` remains empty. So, how can I map the files successfully？@yuzhichang
