75机:Red Hat Enterprise Linux Server 7.0,无外网访问权限
73机:Red Hat Enterprise Linux Server 7.0,无外网访问权限,已安装Docker Server
183机:OS X Yosemite 10.10.4,完全外网访问,用于下载安装包
1. 如果开发环境可联网,则直接通过如下命令进行安装即可:
sudo pip install docker-py
如果没有安装pip命令,可通过如下命令进行安装:
sudo easy_install pip
2. 如果不能连外网,则需要从github的docker-py页面中下载zip包docker-py-master.zip进行离线安装。下载完之后,将zip包从183机scp到75机中:
scp docker-py-master.zip scs@10.11.150.75:/opt/scs/openxxs/
在75机上解压:
unzip docker-py-master.zip
查看setup.py文件,发现有三个依赖包需要安装,且有版本要求:
requirements = [ ‘requests >= 2.5.2‘, ‘six >= 1.3.0‘, ‘websocket-client >= 0.32.0‘, ]
可从如下网站下载 requests、six和websocket-client 三个安装包(如果不知道具体url,运行sudo python setup.py install时会有提示):
requests: https://pypi.python.org/simple/requests/ six: https://pypi.python.org/simple/six/ websocket-client: https://pypi.python.org/simple/websocket-client/
下载完成后scp到75机上再使用 tar -zxvf 解压,依照如下顺序安装:
cd requests-2.7.0 sudo python setup.py install cd ../six-1.9.0 sudo python setup.py install cd ../websocket_client-0.32.0 sudo python setup.py install cd ../docker-py-master sudo python setup.py install
3. 在73机上用同样方式安装docker-py
4. 以Unix Socket方式在73机上启动docker server:
[@tc_150_73 ~]$ sudo docker -d & [1] 1255 [@tc_150_73 ~]$ INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) INFO[0000] [graphdriver] using prior storage driver "devicemapper" WARN[0000] Running modprobe bridge nf_nat failed with message: , error: exit status 1 INFO[0000] Loading containers: start. .. INFO[0000] Loading containers: done. INFO[0000] Daemon has completed initialization INFO[0000] Docker daemon commit=0baf609 execdriver=native-0.2 graphdriver=devicemapper version=1.7.0
在73机上开启若干个docker容器后进行测试,测试如下:
[@tc_150_73 ~]$ python Python 2.7.5 (default, Apr 9 2015, 11:03:32) [GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from docker import Client >>> clt = Client(base_url=‘unix://var/run/docker.sock‘) >>> clt.containers() [{u‘Status‘: u‘Up About a minute‘, u‘Created‘: 1437743168, u‘Image‘: u‘centos:7‘, u‘Labels‘: {}, u‘Ports‘: [], u‘Command‘: u‘/bin/bash‘, u‘Names‘: [u‘/suspicious_galileo‘], u‘Id‘: u‘a81dbf9200fbf6a4180e8b8e80f4fe30b3f8be612ea0e58ac04fb65080429043‘}] >>>
可以看到正常显示了正在运行中的容器,Unix Socket方式测试成功。
5. 关闭73机上刚才开启的docker server(使用service docker stop 和 systemctl docker stop方式停止无效):
sudo killall docker
6. 以TCP方式在73机上启动docker server:
[@tc_150_73 ~]$ sudo docker -H 0.0.0.0:2375 -d & [1] 1625 [@tc_150_73 ~]$ WARN[0000] /!\ DON‘T BIND ON ANY IP ADDRESS WITHOUT setting -tlsverify IF YOU DON‘T KNOW WHAT YOU‘RE DOING /!\ INFO[0000] Listening for HTTP on tcp (0.0.0.0:2375) INFO[0000] [graphdriver] using prior storage driver "devicemapper" WARN[0000] Running modprobe bridge nf_nat failed with message: , error: exit status 1 INFO[0000] Loading containers: start. .... INFO[0000] Loading containers: done. INFO[0000] Daemon has completed initialization INFO[0000] Docker daemon commit=0baf609 execdriver=native-0.2 graphdriver=devicemapper version=1.7.0
在75机上进行测试,测试结果如下:
[@tc_150_75 ~]$ python Python 2.7.5 (default, Apr 9 2015, 11:03:32) [GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from docker import Client >>> clt = Client(base_url=‘tcp://10.11.150.73:30001‘) >>> clt.containers() []
TCP方式测试成功(此时显示的是73机上的正在运行的容器状态,没有,所以为空)。
