docker-compose 管理多个容器

设置docker-compose命令

[root@server1 ~]# mv docker-compose-Linux-x86_64-1.22.0  /usr/local/bin/
[root@server1 ~]# cd /usr/local/bin/
[root@server1 bin]# ln -s docker-compose-Linux-x86_64-1.22.0 docker-compose
[root@server1 bin]# chmod +x docker-compose-Linux-x86_64-1.22.0 
[root@server1 bin]# ll
total 53944
-rwxr-xr-x 1 root root 20416312 May 26 16:47 convoy
-rwxr-xr-x 1 root root 23068627 May 26 16:47 convoy-pdata_tools
lrwxrwxrwx 1 root root       34 Jun  1 11:48 docker-compose -> docker-compose-Linux-x86_64-1.22.0
-rw-r--r-- 1 root root 11750136 Jun  1 11:48 docker-compose-Linux-x86_64-1.22.0

设置compose管理文件

[root@server1 ~]# docker inspect haproxy
           "Cmd": [
                "haproxy",
                "-f",
                "/usr/local/etc/haproxy/haproxy.cfg"
            ],

[root@server1 ~]# mkdir /mnt/compose
[root@server1 ~]# cd /mnt/compose/
[root@server1 compose]# vim docker-compose.yml
web1:
        image: nginx
        expose:
                - 80
        volumes:
                - ./web1:/usr/share/nginx/html

web2:
        image: nginx
        expose:
                - 80
        volumes:
                - ./web2:/usr/share/nginx/html

haproxy:
        image: haproxy
        volumes:
                - ./haproxy/haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg:ro
        links: 
                - web1
                - web2
        ports:
                - "80:80"
        expose:
                - 80

[root@server1 compose]# mkdir web1
[root@server1 compose]# mkdir web2
[root@server1 compose]# echo web1 > web1/index.html
[root@server1 compose]# echo web2 > web2/index.html
[root@server1 compose]# mkdir haproxy
[root@server1 compose]# cd haproxy/
[root@server1 haproxy]# vim haproxy.cfg
