I recently had an opportunity to run though a massive upgrade effort of a Tanzu Kubernetes Grid Integrated Edition (TKGI, formerly Enterprise PKS) installation from 1.7 to 1.8. This also included a vSphere upgrade from 6.7 U3 to 7.0b and an NSX-T upgrade from 2.5.1 to 3.0.1. TKGI 1.8 was just released on June 30th …
This is loosely based off of the instructions at https://docs.vmware.com/en/VMware-Tanzu-Kubernetes-Grid/1.0/vmware-tanzu-kubernetes-grid-10/GUID-manage-instance-authentication.html with some help from https://brianragazzi.wordpress.com/2020/05/12/configure-tanzu-kubernetes-grid-to-use-active-directory/.

The two vSphere plans that come with TKG, dev and prod, will create kubernetes nodes (and the load balancer VM) by performing a full clone of the templates that were created. This will result in a each VM being completely independent, likely having better storage performance (arguable) but taking a while to deploy as the …

Much of this is based off of the instructions noted at Installing Tanzu Kubernetes Grid. We’ll need to start off with an environment where vSphere 6.7 or 7.0 (not technically supported but works with TKG) is already deployed.
