TMC recently added functionality for moving a cluster from one cluster group to another. Cluster groups are a logical construct in TMC that provide means of organizing Kubernetes clusters in a way that makes sense to you and then applying common policies to the clusters in the same group. You can read more about cluster …
I’d been wanting to spend more time with Tanzu Mission Control as I haven’t used it much in the last few months. I’ve been spending nearly all my time with TKG and TKGI and was really starting to get stale on TMC. I decided to run through the relatively easy process of attaching an existing …

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/. It was not a trivial process but the end result was worth it…being able to access your TKG clusters via an AD username/password. I started out with a a TKG management cluster deployed via the instructions in my blog post, Installing TKG 1.1 …

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. I’m using a vApp in vCD as it’s quick and easy to get up and running and costs …
