如何docker 将客户端和服务端都组合成grpc？

Question

我正在尝试使用 grpc 端口的配置创建 docker-compose yaml 文件，但我不知道该怎么做。我研究但无法找到任何示例或通过此 spring 引导阅读 - grpc java

此配置有效，但 grpc 端口未显示，如果我运行在终端中。

您需要将端口标记添加到您的 cartservice 服务，以便您指定需要公开此端口。

//docker-compose.yaml
version: '3.8'

networks:
    cartservice-net:
        driver: bridge

services:


    cartservice:
      image: cartservice:latest
      container_name: cartservice
      depends_on:
        - cart-mysqldb
      restart: always
      build:
        context: ./
        dockerfile: Dockerfile
      ports: 
        - "9090:9090"
      networks:
        - cartservice-net
      environment:
        MYSQL_HOST: cart-mysqldb
        MYSQL_USER: root
        MYSQL_PASSWORD: root
        MYSQL_PORT: 3306

    cart-mysqldb:
      image: mysql:8.0.28
      restart: unless-stopped
      container_name: cart-mysqldb
      ports: 
        - "3307:3306"
      networks:
        - cartservice-net
      cap_add:
        - SYS_NICE
      environment:
        MYSQL_DATABASE: dbpoc
