[root@localhost ~]#
在根目录下创建目录：
[root@localhost /]# mkdir compose

[root@localhost compose]# pwd

/compose
新建文件：
[root@localhost compose]# touch docker-compose.yml
往文件docker-compose.yml添加内容：
version: '2'

services:

App1:

    image: nginx

    ports:

      - "8080:80"

    networks:

      - "netName1"

    volumes:

      - /opt/conf/:/mnt

App2:

    image: nginx

    ports:

      - "8081:80"

    networks:

App3:

    image: nginx

    ports:

      - "8082:80"

    networks:

      - "netName2"

networks:

netName1:

    driver: bridge

netName2:

    driver: bridge
后台服务启动docker-compose.yml的服务：
[root@localhost compose]# pwd

/compose

[root@localhost compose]# docker-compose up -d

Starting compose_App3_1

Starting compose_App2_1

Starting compose_App1_1

[root@localhost compose]#
查看容器运行状态：
[root@localhost compose]# docker-compose ps

     Name              Command          State          Ports

--------------------------------------------------------------------

compose_App1_1   nginx -g daemon off;   Up      0.0.0.0:8080->80/tcp

compose_App2_1   nginx -g daemon off;   Up      0.0.0.0:8081->80/tcp

compose_App3_1   nginx -g daemon off;   Up      0.0.0.0:8082->80/tcp

[root@localhost compose]#
docker-compose其它命令：
[root@docker compose]# docker-compose restart #重启所有容器

[root@docker compose]# docker-compose restart App1 #重启App1

[root@docker compose]# docker-compose stop #停止所有容器

[root@docker compose]# docker-compose stop App1 #停止App1
在APP1中ping APP2：
[root@docker compose]# docker-compose exec App1 bash

root@dd01fa7315ae:/# ping App2

查看共享数据卷：

在/opt/conf下新建nginx.conf文件

[root@localhost conf]# pwd

/opt/conf

[root@localhost conf]# ls

nginx.conf

在挂载目录/mnt下查看nginx.conf文件

[root@localhost conf]#

[root@localhost compose]# docker-compose exec App1 bash

root@bb96cce0d662:/# cd mnt

root@bb96cce0d662:/mnt# ls

nginx.conf

root@bb96cce0d662:/mnt#
在compost目录下（一定要在yml所在的文件夹才行）新增app/web目录，并行新增文件app3.html
[root@localhost web]# pwd

/compose/app/web

[root@localhost web]# ls

app3.html

[root@localhost web]#

app3.html文件内容：

<html>

    <head>

         <meta charset="utf-8">

         <title>Welcome to leonyan's home, this is app3</title>

     </head>

   <body>

   Welcome to leonyan's home, this is app3!

   </body>

</html>
测试打开app3.html
[root@localhost web]# curl http://localhost:8082/app3.html

<html>

    <head>

         <meta charset="utf-8">

         <title>Welcome to leonyan's home, this is app3</title>

     </head>

   <body>
