Prometheus & Grafana Monitoring Stack on TKGS workload cluster in vSphere with Tanzu

In this post, we are going to build on the work already done when we deployed Carvel packages on a Tanzu Kubernetes workload cluster created by the TKG Service in vSphere with Tanzu. We saw in that post what the requirements are, how to use the tanzu command line to set context to a workload cluster, add the TKG v1.4 package repository. We also saw how to use the tanzu CLI to deploy our first package, which was cert manager. We will now continue with the deployment of a number of other packages, such as Contour (for Ingress), External-DNS (to…

Deploying a Tanzu Kubernetes cluster using tanzu CLI in vSphere with Tanzu

Regular readers will have seen a number of articles on this site which use the tanzu command line to create and delete TKGm clusters. TKGm is the nomenclature that I am using to describe multi-cloud TKG clusters (also known as standalone TKG clusters) that can be deployed onto numerous different IaaS, including vSphere. In this post, I want to show you how to use the same tanzu CLI tools to deploy a Tanzu Kubernetes cluster via the TKG service (TKGS) on vSphere with Tanzu. I have always shown that to deploy TKG clusters on vSphere with Tanzu, you login to…

vSphere with Tanzu revisited in vSphere 7.0U3c

Now that VMware has recently released vSphere 7.0U3c, there have been a number of enhancements to vSphere with Tanzu and the TKG Service. Some of these enhancements have been described in recent posts, such as the new v1alpha2 Tanzu Kubernetes Cluster format, as well as new capabilities to the Namespace Service. In this post, I want to go back to basics and look at some changes to the vSphere with Tanzu installation and setup experience. One of the major enhancements is in the area of networking, with DHCP support added for both the Management networks and the Workload network(s). The…

A closer look at the v1alpha2 TanzuKubernetesCluster format in vSphere with Tanzu

Today I wanted to take a closer look at the new Tanzu Kubernetes Cluster YAML format (v1alpha2) which extends the configurability of TKG clusters that are deployed via the TKG Service (TKGS) in vSphere with Tanzu. We will look at this from two viewpoints. The first is to show you the differences when it comes to creating a new TKG cluster, as there are a number of different manifest settings now required with the v1alpha2 format. The second viewpoint is to look at how to upgrade the Tanzu Kubernetes Release (tkr) on an existing cluster which has been upgraded from…

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 v1.4.1 – Some new features

This week, I have been looking at the new features in TKG v1.4.1 for vSphere which dropped very recently. You can find the TKG v1.4.1 Release Notes here. Probably the most notable feature is that TKG v1.4.1 is now supported in Tanzu Mission Control, so you can now add this to your suite of Kubernetes clusters that are centrally managed from TMC. Note that a few things have changed around how to register a TKG management cluster with TMC which I will cover shortly. The other item that caught my attention was the fact that the Identity Management components that…

Tanzu Management Cluster Create 101 (6 of 6) – OS Image [Video]

In this last episode of the series, we look at the final steps involved in building a TKG Management Cluster on vSphere from the UI. In this video, we will look at how to select an OS Image, where to download it from, and once installed, where they live on vSphere as templates. This OS Image is used to build the TKG control plane and worker nodes (virtual machines) in the management cluster. We will finish off with a discussion around where the completed TKG management cluster configuration file lives on your desktop, and what else it can be used…
