pyvmomi 实现VMware自动化


运维离不开自动化,python的发展更是给自动化注入了一剂兴奋剂;还记得当时公司年会,大家都在嗨皮,苦逼的运维攻城狮还在卖力的给一个大客户手动开通500台云主机的情形,现在想想好傻O(∩_∩)O哈哈~。如果早点接触pyVmomi,就不至于这么苦逼了。

pyVmomi is the Python SDK for the VMware vSphere API that allows you to manage ESX, ESXi, and vCenter.官方如是说。自己这里写篇博客整理一下,也希望对还停留在手工时代的同学有所帮助。

坏境配置:

1、网络环境:

安装pyvmomi的server和VMware vCenter 网络打通;

2、系统环境:

pyvmomi用pip安装,所以需要有python和pip;pyvmomi 6.0.0需要的python版本支持为2.7, 3.3 和3.4,支持的vSphere 版本为:6.0, 5.5, 5.1 和 5.0。

安装如下:

$sudoapt-getinstallpython-pip
$sudopipinstallpyvmomi
$sudopipfreeze|greppyvmomi#查看安装的pyvmomi版本,现在是6.0版本
pyvmomi==6.0.0#如果已经安装过,升级用pipinstall--upgradepyvmomi

或者也可以下载源码包安装,https://github.com/vmware/pyvmomi.git:

$sudopythonsetup.pyinstall

3、pyvmomi提供了一些社区样本项目,可以参考编写自己的代码:

gitclonehttps://github.com/vmware/pyvmomi-community-samples.git

4、下面是 pyvmomi给出的获取所有vm的脚本:

5、执行之后输出格式如下:
