易學筆記-Docker-Compose相關
- 下載docker-compose：
curl -L "https://github.com/docker/compose/releases/download/1.8.1/docker-compose-$(uname -s)-$(uname -m)" > /usr/local/bin/docker-compose 存放路徑：/usr/local/bin/docker-compose
- 檢視docker-compose版本
[[email protected] ~]# docker-compose version
docker-compose version 1.8.1, build 878cff1
docker-py version: 1.10.3
CPython version: 2.7.9
OpenSSL version: OpenSSL 1.0.1e 11 Feb 2013

- 在根目錄下建立目錄：
[[email protected] /]# mkdir compose
[[email protected] compose]# pwd
/compose
- 新建檔案：
[[email protected] compose]# touch docker-compose.yml
- 往檔案docker-compose.yml新增內容：
version: '2'
services:
App1:
image: nginx
ports:
- "8080:80"
networks:
- "netName1"
volumes:
- /opt/conf/:/mnt
App2:
image: nginx
ports:
- "8081:80"
networks:
- "netName1"
volumes:
- /opt/conf/:/mnt
App3:
image: nginx
ports:
- "8082:80"
networks:
- "netName2"
networks:
netName1:
driver: bridge
netName2:
driver: bridge
- 後臺服務啟動docker-compose.yml的服務：
[[email protected] compose]# pwd
/compose
[[email protected] compose]# docker-compose up -d
Starting compose_App3_1
Starting compose_App2_1
Starting compose_App1_1
[[email protected] compose]#
- 檢視容器執行狀態：
[[email protected] 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
[[email protected] compose]#
- docker-compose其它命令：
[root@docker compose]# docker-compose restart #重啟所有容器
[root@docker compose]# docker-compose restart App1 #重啟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：
[[email protected] compose]# docker-compose exec App1 bash
[email protected]:/# ping App2
PING App2 (172.18.0.3): 56 data bytes
64 bytes from 172.18.0.3: icmp_seq=0 ttl=64 time=0.059 ms
64 bytes from 172.18.0.3: icmp_seq=1 ttl=64 time=0.108 ms

64 bytes from 172.18.0.3: icmp_seq=3 ttl=64 time=0.062 ms
- 檢視共享資料卷：
在/opt/conf下新建nginx.conf檔案
[[email protected] conf]# pwd
/opt/conf
[[email protected] conf]# ls
nginx.conf
在掛載目錄/mnt下檢視nginx.conf檔案
[[email protected] conf]#
[[email protected] compose]# docker-compose exec App1 bash
[email protected]:/# cd mnt
[email protected]:/mnt# ls
nginx.conf
[email protected]:/mnt#
- 在compost目錄下（一定要在yml所在的資料夾才行）新增app/web目錄，並行新增檔案app3.html
[[email protected] web]# pwd
/compose/app/web
[[email protected] web]# ls
app3.html
[[email protected] web]#
app3.html檔案內容：
<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>
- 測試開啟app3.html
[[email protected] 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>
Welcome to leonyan's home, this is app3!
</body>
</html>
