docker-compose可以一次性安裝多個容器，並且能按照順序依次啟動，可以更方便的啟動容器和能解決依賴問題

安裝單機編排工具： docker-compose

yum install -y epel-release
yum install -y python-pip
pip install docker-compose

docker-compose version ,出現版本號就是成功

vim docker-compose.yml

version: "2"
services:
  app1:
    image: 127.0.0.1:5000/chao/nginx
    ports:
      - "8080:80"
 

    networks:
      - "net1"
    volumes:
      - /data/:/data
  app2:
    image: redis
    networks:
      - "net2"
    volumes:
      - /data/:/data1
    entrypoint: tail -f /etc/passwd
networks:
  net1:
    driver: bridge
  net2:
    driver: bridge

啟動容器：

[[email protected] compose]# docker-compose up -d
 

Creating network "compose_net2" with driver "bridge"
Creating network "compose_net1" with driver "bridge"
Creating compose_app2_1 ... done
Creating compose_app1_1 ... done

up代表啟動， -d代表後臺啟動

[[email protected] compose]# docker ps
CONTAINER ID        IMAGE                       COMMAND                  CREATED              STATUS              PORTS                    NAMES

關閉容器：（關閉的同時移除了容器）

[[email protected] compose]# docker-compose down
Stopping compose_app2_1 ... done
Stopping compose_app1_1 ... done
Removing compose_app2_1 ... done
Removing compose_app1_1 ... done
Removing network compose_net2
