Pyvmomi for VMware Automation

Pyvmomi for VMware Automation

O & M is inseparable from automation. The development of python has injected a dose of doping into automation. I still remember that at the company's annual meeting, everyone was doing well, the tough O & M team is still trying to manually activate 500 cloud hosts for a major account. Now, let's think about the silly O (Taobao _ Taobao) O Haha ~. If you get started with pyVmomi earlier, it won't be so hard.

PyVmomi is the Python SDK for the VMware vSphere API that allows you to manage ESX, ESXi, and vCenter. I want to write a blog here to help students who are still in the manual age.

Bad Environment Configuration:

1. Network Environment:

The server installed with pyvmomi is interconnected with the VMware vCenter network;

2. system environment:

Pyvmomi is installed with pip. Therefore, python and pip are required. python versions 2.7, 3.3, and 3.4 are required for pyvmomi 6.0.0, and vSphere versions 6.0, 5.5, 5.1, and 5.0 are supported.

The installation is as follows:

$ Sudoapt-getinstallpython-pip $ installation $ sudopipfreeze | greppyvmomi # Check the installed version of pyvmomi. version 6.0 is pyvmomi = 6.0.0 # If installed, upgrade pipinstall -- upgradepyvmomi

You can also download and install the source code package, https://github.com/vmware/pyvmomi.git:

$sudopythonsetup.pyinstall

3. pyvmomi provides some community sample projects. You can refer to writing your own code:

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

4. The following is the script for getting all VMS provided by pyvmomi:
