A closer look at the vSphere with Tanzu Namespace Service

Now that vSphere 7.0U3c is available, I thought it might be a good time to revisit some of the vSphere with Tanzu features that have appeared in recent editions. The first of these is the Namespace Service, which enables dev-ops personas to create their own Supervisor Namespaces through the command line via kubectl. We have extended this feature in vSphere 7.0U3c to allow dev-ops to add their own Kubernetes labels and annotations. Let’s take a look at how this works, and how the vSphere Administrator can put guardrails around the amount of vSphere resources this persona can consume when creating…

TKG v1.4 LDAP (Active Directory) integration with Pinniped and Dex

LDAP integration with Pinniped and Dex is a topic that I have written about before, particularly with TKG v1.3. However, recently I had reason to deploy TKG v1.4 and noticed some nice new enhancements around LDAP integration that I thought it worthwhile highlighting. One is the fact that you no longer need to have a web browser available in the environment where you are configuring LDAP credentials which was a requirement is the previous version. In this post, I will deploy a TKG v1.4 management cluster on vSphere. This environment uses the NSX ALB to provide IP addresses for both…

TKG v1.4 Prometheus + Grafana Package Deployment: package reconciliation failed

I was recently running through the exercise of deploying Cert Manager, Contour (+ Envoy Ingress), Prometheus and Grafana packages available with TKG v1.4, just to see what steps were involved in setting up a full monitoring stack for my TKG cluster. This was a TKG deployment to vSphere, using the NSX Advanced Load Balancer for Load Balancer functionality. You can read about the new enhancements around the NSX ALB and TKG v1.4 here.  Honestly, it is pretty straight-forward, with some detailed documentation on the topic available here. Everything was plain sailing until I tried to deploy the Grafana package with,…

Cleaning up NSX ALB (Avi) Pool when referred to by L4PolicySet

I’ve been using the NSX Advanced Load Balancer for many of my experiments in the lab. Sometimes I build configurations that do not work correctly, especially around TKG. From time to time, I find that my TKG management cluster does not stand up successfully, and so I have to manually clear it down and start over. From time to time, this has left my NSX ALB with some objects that also need to be manually cleaned up. While I can delete Virtual Services and Virtual IP Addresses with ease in the NSX ALB portal/UI, I am sometimes left in a…

TKG v1.4 & NSX ALB – Ingress Health Monitor Anomaly

As I continue to look at TKG version 1.4, I wanted to start using VMware NSX Advanced Load Balancer integrated with the Project Contour (Envoy Ingress) package. Project Contour is a control plane for the Envoy Ingress that is included with the package, but which also has the ability to dynamically change the Ingress configuration. It is included as an add-on package to TKG v1.4. To use it, I deployed a TKG management cluster and a TKG workload cluster using an NSX ALB (v 20.1.5) for the Load Balancing Service. I then proceeded to deploy the Contour package. While the…

TKG v1.4 – Some nice new features

Over the last week or so, VMware recently announced the release of TKG version 1.4. On reading through the release notes, there were a few features that caught my eye, so I thought I would deploy a cluster and take a closer look. In particular, two features were of interest. The first of these is support for the NSX Advanced Load Balancer (ALB) service in workload clusters, which is available through the Avi Kubernetes Operator (AKO). This is applicable when TKG is deployed on vSphere. There is also new support for the NSX ALB as a control plane endpoint provider.…

VMworld 2021 – My Top 10 Picks around Kubernetes

Well here we are again – another VMworld has come around. As most of you will know, VMworld 2021 is going to be another “fully virtual” event (no pun intended), the same as it was for VMworld 2020. Hard to imagine that it is 3 years since I presented at VMworld 2018 in Las Vegas, and 2 years since I presented at VMworld EMEA 2019 in Barcelona. Strange days indeed. Let’s hope we can all get together at VMworld 2022 and have a blast. Like previous years, I have picked out a few presentations that I plan on attending at…
