docker compose可以方便我們快捷高效地管理容器的啟動、停止、重啟等操作，它類似linux下的shell腳本，基於yaml語法，在該文件裏我們可以描述應用的架構，比如用什麽鏡像、數據卷、網絡模式、監聽端口等信息。我們可以在一個compose文件中定義一個多容器的應用，然後通過該compose來啟動這個應用。

編輯docker-compose.yml

version: "2"
services:
  app1:
    image: centos:nginx
    ports:
      - "8080:80"
    networks:
      - "net1"
    volumes:
      - /data/:/data
  app2:
    image: centos:net-tools
    networks:
      - "net2"
    volumes:
      - /data/:/data1
    entrypoint: tail -f /etc/passwd
networks:
  net1:
    driver: bridge
  net2:
    driver: bridge
