求助，微服务用jar包用bat启动正常启动，打包到docker里后链接报错（已解决）

[create_bug]

 

这个是我的dockerfile 包括jar包一共有5个这样的

version: '3.8'

services:
  dc3-center-auth:
    image: dc3-center-auth:2024.08.02
    ports:
      - "8082:8082"
    container_name: dc3-center-auth
    environment:
      - JAVA_OPTS=-Xmx512m
    networks:
      - my-network

  dc3-center-data:
    image: dc3-center-data:2024.08.02
    ports:
      - "8083:8083"
    container_name: dc3-center-data
    environment:
      - JAVA_OPTS=-Xmx512m
    networks:
      - my-network

  dc3-center-manager:
    image: dc3-center-manager:2024.08.02
    ports:
      - "8066:8066"
    container_name: dc3-center-manager
    environment:
      - JAVA_OPTS=-Xmx512m
    networks:
      - my-network

  dc3-driver-modbus-tcp:
    image: dc3-driver-modbus-tcp:2024.08.02
    ports:
      - "8096:8096"
    container_name: dc3-driver-modbus-tcp
    environment:
      - JAVA_OPTS=-Xmx512m
    networks:
      - my-network

  dc3-gateway:
    image: dc3-gateway:2024.08.02
    ports:
      - "8097:8097"
    container_name: dc3-gateway
    environment:
      - JAVA_OPTS=-Xmx512m
    networks:
      - my-network

networks:
  my-network:
    driver: bridge

这个是我的yml文件配置，我是先打包镜像然后用

docker-compose -f dc3-docker-compose-dev.yml up -d dc3-gateway dc3-driver-modbus-tcp dc3-center-manager dc3-center-data dc3-center-auth

一次性打包。一般用bat方式启动的时候可以在docker部署的nacos查看服务。但是我从docker里启动后五个全部报错然后停止。日志主要是报RabbitMQ服务和MySQL服务无法建立连接，研究一天了不清楚怎么回事，bat正常在docker就会有问题

---

解决方案：因为在docker内部启动MySQL镜像担心端口冲突映射端口和端口设置为33306和3306；在jar里的设置的端口访问都是33306，但是进入内部后应该访问的3306.

其次可能是配置项问题，导致两个Docker Compose即使挂在了同一个networks也无法互相通信。目前没有好的方法解决问题只能无奈把所有的打包到一起
