我试图在docker中部署gRPC（go）服务器并在本地端口中公开端口，但是端口绑定不起作用

Question

I tried to deploy gRPC server and mongodb in docker. After that I trying to binding docker ports to my local ports. mongodb ports binding was working fine. But, gRPC server ports are not binding my local port

ports:
  - "50051:50051"

like this i tried in docker-compose.yml

docker-compose.yml

services:
  auth_server:
    container_name: auth_service
    build: .
    command: go run server.go
    volumes:
      - .:/go/src/auth_server
    working_dir: /go/src/auth_server
    ports:
      - "50051:50051"
    environment:
      PORT: 50051

In client gRPC file I used host and port like, 0.0.0.0:50051

conn, err := grpc.Dial("0.0.0.0:50051", grpc.WithInsecure())

but it was not working. I can't find any bug, so I assume I am doing something incorrectly.

Answer 1

You should use 127.0.0.1:50051 when connecting from a client on the host machine, or auth_server:50051 if you are connecting from docker-compose network.
