docker-compose自定义子网及固定容器IP

docker-compose定义子网，需要指定version为2，如果version设置为3则会报如下错误

ERROR: The Compose file './docker-compose-xxx.yml' is invalid because:
networks.default.ipam.config value Additional properties are not allowed ('gateway' was unexpected)

配置Docker-compose自定义子网及固定IP

version: '2'    #这里必须是版本2
services: 
  docker-nacos-server:
    image: nacos/nacos-server:latest
    container_name: nacos-server-2
    ports:
      - "8848:8848"
      - "9555:9555"
#------------------ 引用子网 ----------------------------------#      
    networks:
      nacosnat:  #nacosnat是自定义的网络名称
        ipv4_address: 10.100.20.10   #固定IP为10.100.20.10
#------------------ 结束区域 ----------------------------------#       
    restart: on-failure
    privileged: true
    environment:
      PREFER_HOST_MODE: ip
      SPRING_DATASOURCE_PLATFORM: mysql
      NACOS_SERVER_IP: 192.168.1.202
      NACOS_SERVERS: 192.168.1.201:8848 192.168.1.202:8848 192.168.1.203:8848

      MYSQL_MASTER_SERVICE_PORT: 3305
      MYSQL_MASTER_SERVICE_DB_NAME: nacos_config
      MYSQL_MASTER_SERVICE_USER: root
      MYSQL_MASTER_SERVICE_PASSWORD: root
      MYSQL_SLAVE_SERVICE_HOST: 192.168.1.201
      MYSQL_SLAVE_SERVICE_PORT: 3304
    volumes:
      - /data/A/nacos2:/home/nacos/logs 
      - ../init.d/custom.properties:/home/nacos/init.d/custom.properties

#------------------ 定义子网信息 ----------------------------------# 
networks:
  nacosnat:  #nacosnat是自定义的网络名称
    driver: bridge
    ipam:
      config:
        - subnet: 10.100.20.0/24     #指定子网
          gateway: 10.100.20.1       #指定网关
#------------------ 结束区域 ----------------------------------#         

验证容器IP

$ docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 1c68d336c524
10.100.20.10
