I had been so focused on TKG on vSphere lately that I had been overlooking the fact that we’ve automated the process for standing up a cluster on AWS as well. While it’s far easier to do this via the TKG UI, I wanted to take a stab at it entirely from the command line. …

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 …
