It has been awhile since I have updated my Tanzu Kubernetes Grid (TKG) Demo Appliance Fling, which is a virtual appliance that enables anyone to go from zero to Kubernetes in less than 30 minutes with just an SSH client and a web browser. For VMware Cloud on AWS customers interested in running TKG, this is a great way to quickly get started on a proof of concept, demo or for development and testing purposes. One great benefit is that everything required for TKG is self contained within the appliance including an embedded Harbor registry and the respective TKG container images, great for air-gapped or non-internet accessible environments.
Here is a summary of what is new:
Support for latest TKG 1.1.3
There have been several of smaller releases to TKG since their 1.0.0 release but due to their short lifecycle, I decided to hold off. Behind the scenes, I have actually been working closely with TKG team on the latest TKG 1.1.3 release which was just release last week. One really cool feature that was introduced in TKG 1.1.2 is the ability to upgrade an existing TKG Workload Cluster to a newer version of Kubernetes.
With TKG 1.1.3, support for Kubernetes v1.18.6 and v1.17.9 is now possible and the latest version of the demo appliance will also support this workflow. In fact, I have also updated my TKG Workshop Guide to include all new updates including the upgrade workflow. To reduce the maintenance burden on myself, the TKG Demo Appliance 1.0.0 will be removed in the near future, for now it has been deprecated but all existing content is still available. I highly recommend checking out the latest version as you will get all the latest features of TKG.
