拓撲：
1. 在CentOS7上，django項目目錄爲/smb/public/eclipse-workspace/DjangoProj/djcode/mysite, 映射到容器django中的目錄爲/tmp
2. 在CentOS7上，mysql數據庫對應的目錄爲/var/lib/docker/volumes/mysql,映射到容器mysql中的目錄爲/var/lib/mysql
步驟：
1. 獲取django鏡像（如果是用python2.7開發的就獲取django 2.7版本的鏡像）：
[root@localhost ~]# docker pull django:python2-onbuild
2. 獲取mysql鏡像
[root@localhost ~]# docker pull mysql
3. 進入獲取的django鏡像，進行測試,發現缺少django庫和MySQL-python庫，於是使用pip安裝這兩個庫:
[root@localhost ~]# docker run -it --name=django_test -v /smb/public/eclipse-workspace/DjangoProj/djcode/mysite/:/tmp:rw -p 8001:8001 django:python2-onbuild /bin/bash
root@cf574e2deca4:/usr/src/app# cd /tmp/
root@cf574e2deca4:/tmp# python manage.py check
Traceback (most recent call last):
File "manage.py", line 17, in <module>
"Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
root@cf574e2deca4:/tmp# pip install django
...
...
Successfully installed django-1.11.7 pytz-2017.3
root@cf574e2deca4:/tmp# python manage.py check
Traceback (most recent call last):
...
...Error loading MySQLdb module: No module named MySQLdb.

root@cf574e2deca4:/tmp# pip install MySQL-python
...

Successfully installed MySQL-python-1.2.5
4. 提交對django:python2-onbuild鏡像的更改到自己的倉庫（owenchen1992/mydjango:python2.7）
[root@localhost ~]# docker commit django_test owenchen/django_test
sha256:55376230bf7539f0ac7a3e083270f48f8ee8c2bfec247c2e39b4616e2cf688de
5. 參考http://blog.csdn.net/m0_37904728/article/details/78621191進入mysql容器，創建所需的數據庫，同時參考http://blog.csdn.net/m0_37904728/article/details/78622843確保host上存放數據的卷正確對應到mysql容器。（commit後的兩個鏡像名稱爲owenchen1992/mydjango:python2.7和owenchen1992/mysql）
6. 查看兩個容器的ip,確保他們網絡可以互通：
[root@localhost ~]# docker network inspect bridge
[
...
"Containers": {
"09faeb3f1de3c6b8e6970fed796104c89023f04a37d050f837d6bf2b9755fcf8": {
"Name": "mysql",
"EndpointID": "12fe6290993fc3d7e156c279e9bd7904beb8cc9e5e7d99722063003bf2981f2e",
"MacAddress": "02:42:ac:11:00:02",
"IPv4Address": "172.17.0.2/16",
"IPv6Address": ""
},
"b4236ebf6c826e92e084f2f804a308111c3cf481eb06a0d0de9f81cb5f38c887": {
"Name": "django",
"EndpointID": "192b0e08792231b880f2a3843c9ba996beb73ffb50316dd83b1ca935f7986c6c",
"MacAddress": "02:42:ac:11:00:03",
"IPv4Address": "172.17.0.3/16",
"IPv6Address": ""
}
},
...
]
7. 這時啓動兩個容器，名稱爲django和mysql：
[root@localhost ~]# docker run -it --name=django -v /smb/public/eclipse-workspace/DjangoProj/djcode/mysite/:/tmp:rw -p 8000:8000 owenchen1992/mydjango:python2.7 /bin/bash
[root@localhost ~]# docker run --name=mysql -p 3306:3306 -v /var/lib/docker/volumes/mysql:/var/lib/mysql:rw -d owenchen1992/mysql
8.進入容器django，進行系統檢查，檢查通過：
[root@localhost ~]# docker exec -it django bash
root@cf574e2deca4:/usr/src/app# cd /tmp
root@cf574e2deca4:/tmp# python manage.py check
System check identified no issues (0 silenced).
9.運行django服務器：
root@b4236ebf6c82:/tmp# python manage.py runserver 0.0.0.0:8000
Performing system checks...
System check identified no issues (0 silenced).

Quit the server with CONTROL-C.
10.運行成功，在host上瀏覽器訪問django容器的ip地址和8000端口即可看到頁面
