标题: 在docker compose中配置外部网络

定义外部网络

定义一个外部网络只需为其添加子配置项external，示例

version: "3.7"
networks:
  docker-compose-network:
  external-network-custom-network:
    external:
      name: custom-network

将容器加入该网络

之后为需要加入该外部网络的容器配置网络选项，示例

version: "3.7"
services:
  redis:
    image: redis
    command: redis-server /etc/redis/redis.conf
    volumes:
      - /etc/redis/redis.conf:/etc/redis/redis.conf
    ports:
      - 6379:6379
    networks:
      - docker-compose-network
      - external-network-custom-network
