Mastering PowerCLI

Overview of this book

Have you ever wished that every morning you could automatically get a report with all the relevant information about your datacenter in exactly the same format you want? Or whether you could automate that boring, exhausting task? What if some crucial task needs to be performed on a regular basis without any error? PowerCLI scripts do all that and much more for VMware environments. It is built on top of the popular Windows PowerShell, with which you can automate server tasks and reduce manual input, allowing you to focus on more important tasks. This book will help you to achieve your goals by starting with a short refresher on PowerShell and PowerCLI and then covering the nuances of advanced functions and reusable scripts. Next you will learn how to build a vSphere-powered virtualized datacenter using PowerCLI while managing different aspects of the environment including automated installation, network, and storage. You will then manage different logical constructs of vSphere environment and different aspects of a virtual machine. Later, you will implement the best practices for a security implementation in vSphere Environment through PowerCLI before discovering how to manage other VMware environments such as SRM, vCloud Director and vCloud Air through PowerCLI. You will also learn to manage vSphere environments using advanced properties by accessing vSphere API and REST APIs through PowerCLI. Finally, you will build a Windows GUI application using PowerShell followed by a couple of sample scripts for reporting and managing vSphere environments with detailed explanations of the scripts. By the end of the book, you will have the required in-depth knowledge to master the art of PowerCLI scripting.

Using host profiles


In the preceding section, we learned how to manipulate and create custom ESXi images using PowerCLI cmdlets. So, now let's take a closer look at how to manipulate host profiles so that we can use both at a later stage in order to automate ESXi deployments. In case of VMware technologies, a host profile is a profile that stores all the configuration information of a host. We can configure an ESXi host as required and mark the host as the golden standard. Next, we create a host profile from the configuration of this host. Once the profile is ready, we can simply apply the profile to other hosts so that they can be automatically configured. This way, we can ensure consistency between host configurations across the entire infrastructure.

For this lab, we will get the following architecture:

We have a vcenter.lab.com server as a vCenter server. Under this, we have a datacenter named Datacenter. A cluster named Lab Cluster is created under Datacenter. The cluster has two ESXi...
