Tkg

This is the second post in a series of two post detailing the steps that I took to install Kubeapps running on a TKG 1.3 cluster on AWS configured to allow user authentication via the TKG identity management:

• The first post focuses on the TKG 1.3 setup required to get a workload clusters with identity management (using your chosen identity provider),
• This followup post details the related Kubeapps installation and configuration on the TKG 1.3 workload cluster.

The details below assume that you’ve already successfully created your TKG management and workload clusters configured with identity management and verified that you can authenticate with both clusters using your identity provider (ie. not admin credentials).

Way back in 2020 I’d detailed how I’d setup a Tanzu Kubernetes Grid 1.1 management cluster with OpenID Connect support (for single sign-on) before installing Kubeapps with single sign-on on that management cluster.

Recently TKG 1.3 was released and the identity management support in TKG has changed significantly, so it’s time to see what’s different when setting up a TKG cluster with identity management as well as how we can run Kubeapps on TKG 1.3 with identity management. You will of course need to work through the TKG 1.3 documentation for your environment, I’ll just highlight the significant points and small issues that I needed to work around, due to my environment.

This is part two of a series detailing the steps required to run Kubeapps on a VMware TKG management cluster (on AWS) configured to allow users to deploy applications to multiple workload clusters, using the new multicluster support in Kubeapps. Though details will differ, a similar configuration works on other non-TKG multicluster setups as well.

The first post described setting up your VMware TKG management cluster with two OpenIDConnect-enabled workload clusters. This post assumes you have your TKG environment setup as described there and focuses on the Kubeapps installation and configuration. The following video demos the result:

Andres and I have been doing quite a bit of feature work in Kubeapps over the past months at VMware and one of the key features that I’ve been working on personally is enabling Kubeapps users to deploy applications not only on the cluster on which Kubeapps is installed, but to multiple other clusters as well.

Enter VMware Tanzu Kubernetes Grid (TGK): an “Enterprise-ready Kubernetes runtime which streamlines operations across multi-cloud infrastructure”, so naturally I was keen to test out running Kubeapps on TKG and deploying applications to a set of TKG-managed clusters.
