PowerShell Script to Configure an NSX-T Load Balancer for the vRealize Suite & Workspace ONE Access

As part of my role in the VMware Hyper-converged Business Unit (HCIBU) I spend a lot of time working with new product versions testing integrations for next-gen VMware Validated Designs and Cloud Foundation. A lot of my focus is on Cloud Operations and Automation (vROPs, vRLI, vRA etc) and consequently I regularly need to deploy environments to perform integration testing. I will typically leverage existing automation where possible and tend to create my own when i find gaps. Once such gap was the ability to use PowerShell to interact with the NSX-T API. For anyone who is familiar with setting up a load balancer for the vRealize Suite in NSX-T – there are a lot of manual clicks required. So i set about creating some PowerShell functions to make it a little less tedious and to speed up getting my environments setup so i could get to the testing faster.

There is comprehensive NSX-T API documentation posted on code.vmware .com that I used to decipher the various API endpoints required to complete the various tasks:

  • Create the Load Balancer
  • Create the Service Monitors
  • Create the Application Profiles
  • Create the Server Pools
  • Create the Virtual Servers

The result is a PowerShell module with a function for each of the above and a corresponding JSON file that is read in for the settings for each function. I have included a sample JSON file to get you started. Just substitute your values.

Note: You must have a Tier-1 & associated segments created. (I’ll add that functionality when i get a chance!)

PowerShell Module, Sample JSON & Script are posted to Github here

NSX IPSec VPN between datacenters (multi site/region)

I’m doing some lab work with my team at the moment and we were gifted some hardware to do some multi region validation. Both systems (a VxRack SDDC & a VxRail) are in 2 separate datacenters, and both are using private IP addressing that is not routable between datacenters. As part of the validation we need both systems to be able to communicate with each other, however we dont control the inter lab switching to put in place the necessary routes to enable this. Rather than go through a change control process with the keepers of that gate we decided to get creative and have some fun (and hopefully learn something!) by setting up an NSX IPSec VPN between the labs.

Disclaimer: There are many better ways to do this for a permanent lab setup (i.e. BGP to the core with routes) but this was done on borrowed kit that was never initially designed with inter lab routing as a requirement, with no direct control on the inter lab switches, and we would also like to put it back the way we found it so dont want to make sweeping architectural changes!
