一、修改docker.service文件，添加监听端口

vi /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

重启docker服务

systemctl daemon-reload
systemctl start docker

二、idea的docker-compose启动配置（分四步）

1. Docker（Server）
2. docker-compose.yml

   version : '3.9'
   services:
     ruoyi-gateway-test:
       #image: ruoyi/ruoyi-gateway:1.0.0
       container_name: ruoyi-gateway-test
       build:
         context: ../ruoyi-gateway
         dockerfile: Dockerfile
       environment:
         # 时区上海
         TZ: Asia/Shanghai
       volumes:
         # 配置文件
         - /docker/zj-cloud/logs/ruoyi-gateway/:/ruoyi/ruoyi-gateway/logs/
       ports:
         - "8889:8889"
       command: [
         "--server.port=8889"
       ]
       privileged: true
       network_mode: "host"
       restart: always
     ruoyi-auth-test:
       #image: ruoyi/ruoyi-auth:1.0.0
       container_name: ruoyi-auth-test
       build:
         context: ../ruoyi-auth
         dockerfile: Dockerfile
       ports:
         - "9299:9299"
       volumes:
         # 配置文件
         - /docker/zj-cloud/logs/ruoyi-auth/:/ruoyi/ruoyi-auth/logs/
       privileged: true
       network_mode: "host"
       restart: always
     ruoyi-modules-system-man-test:
       #image: ruoyi/ruoyi-modules-system-man:1.0.0
       container_name: ruoyi-modules-system-man-test
       build:
         context: ../ruoyi-modules/ruoyi-system-man
         dockerfile: Dockerfile
       environment:
         # 时区上海
         TZ: Asia/Shanghai
       volumes:
         # 配置文件
         - /docker/zj-cloud/logs/ruoyi-modules-system-man/:/ruoyi/ruoyi-modules-system-man/logs
       ports:
         - "9399:9399"
       privileged: true
       network_mode: "host"
       restart: always
     ruoyi-modules-system-ops-test:
       #image: ruoyi/ruoyi-modules-system-ops:1.0.0
       container_name: ruoyi-modules-system-ops-test
       build:
         context: ../ruoyi-modules/ruoyi-system-ops
         dockerfile: Dockerfile
       environment:
         # 时区上海
         TZ: Asia/Shanghai
       volumes:
         # 配置文件
         - /docker/zj-cloud/logs/ruoyi-modules-system-ops/:/ruoyi/ruoyi-modules-system-ops/logs
       ports:
         - "9499:9499"
       privileged: true
       network_mode: "host"
       restart: always
     ruoyi-modules-man-test:
       #image: ruoyi/ruoyi-modules-system-ops:1.0.0
       container_name: ruoyi-modules-man-test
       build:
         context: ../ruoyi-modules/ruoyi-man
         dockerfile: Dockerfile
       environment:
         # 时区上海
         TZ: Asia/Shanghai
       volumes:
         # 配置文件
         - /docker/zj-cloud/logs/ruoyi-modules-man/:/ruoyi/ruoyi-modules-man/logs
       ports:
         - "9302:9302"
       privileged: true
       network_mode: "host"
       restart: always
     ruoyi-modules-ops-test:
       #image: ruoyi/ruoyi-modules-system-ops:1.0.0
       container_name: ruoyi-modules-ops-test
       build:
         context: ../ruoyi-modules/ruoyi-ops
         dockerfile: Dockerfile
       environment:
         # 时区上海
         TZ: Asia/Shanghai
       volumes:
         # 配置文件
         - /docker/zj-cloud/logs/ruoyi-modules-ops/:/ruoyi/ruoyi-modules-ops/logs
       ports:
         - "9301:9301"
       privileged: true
       network_mode: "host"
       restart: always

3. 命令，一定要勾选build，每次尽量重新构建镜像，同时如果需要单独启动/build某几个服务，就只需要输入对应服务名，逗号隔开，为空则时启动/build全部服务

4. 启动之前可以执行maven 的clean和package命令【clean package -Dmaven.test.skip=true -U】
