User guide

docker deployment

  1. We can enable gRPC mode by setting these environment variables in api and worker container in docker-compose.yaml:
QDRANT_GRPC_ENABLED:  'true'    
QDRANT_GRPC_PORT: xxxx
  1. Add port mapping to port 6334 of the qdrant container as below:
   qdrant:
     image: langgenius/qdrant:v1.7.3
     restart: always
     volumes:
       - ./volumes/qdrant:/qdrant/storage
     environment:
       QDRANT_API_KEY: 'difyai123456'
     # uncomment to expose qdrant port to host
      ports:
       - "6333:6333"
       - "xxxx:6334"
  1. You can replace xxxx to your port

source deployment(api)

  1. Add 2 lines to api/.env as below:
QDRANT_GRPC_ENABLED=true
QDRANT_GRPC_PORT=xxxx
  1. You can replace xxxx to your port
