Deploy a Tanzu Kubernetes (TKG) cluster in vSphere with Kubernetes (Video)

This video will show the steps involved in deploying a fully functional Tanzu Kubernetes Grid cluster (TKG) via vSphere with Kubernetes. We will see how to build and sync a content library for the TKG control plane and worker node images. We will walk through the creation of a new namespace, and review the manifest file used for the creation of the cluster. Once deployed, we will switch contexts from the namespace used to build the cluster and place ourselves in the context of the new TKG cluster. From there, we will run some kubectl commands to query the cluster.…

vSphere with Kubernetes – Namespaces, Harbor and PodVMs (Video)

This short video will show you some of the initial steps that one might take once vSphere with Kubernetes has been successfully deployed via VMware Cloud Foundation (VCF) 4.0 and SDDC Manager. And FYI, as I know a number of reader have been asking this question, VCF 4.0 is now officially GA. In this short video, I will introduce you to the namespace concept in vSphere with Kubernetes as a way of allocating vSphere resources between multiple tenants. As well, we will see how to enable and use Harbor as a Container Image Registry. Finally we will deploy a StatefulSet…

Deploying vSphere with Kubernetes via VCF 4.0 SDDC Manager (Video)

In this post, I am going to share another short video that I made which highlights the main steps involved when deploying vSphere with Kubernetes from VCF 4.0 SDDC Manager. You can find the complete steps here in this previous post which shows how to deploy vSphere with Kubernetes in a Workload Domain. The video will talk you through the validation steps that are done in SDDC Manager, and then show you the complete vSphere with Kubernetes deployment in the vSphere UI. We will see the configuration changes that are made to NSX-T during the process as well. At the…

Automated NSX-T 3 Edge Cluster deployment in VCF 4.0 (Video)

A little while back, I wrote a post about what steps are involved in automatically deploying an NSX-T 3 Edge Cluster in VMware Cloud Foundation 4.0. I also though that it might be useful to show the steps involved in a very short video (less than 4 minutes in length). Automatic deployment of NSX-T 3 Edge clusters in VCF 4.0 is a really nice new feature, and those of us who have gone through the manual process of creating NSX-T Edge clusters can testify. Check out the video on YouTube here:

ESXi host Time & date actions menu not working in 7.0 host client – Workaround

This is something I noticed in the vSphere 7.0 host client. The actions button in the host client for the System > Time & date isn’t working. This means that we have to find an alternate method to enable NTP on the stand-alone host. What we will need to do is the following: Configure NTP startup policy and NTP server(s) Enable the NTP port in the Firewall Rules Start the NTP service manually Verify NTP is working 1. Configure NTP startup policy and NTP server To begin, select the correct NTP service startup policy and NTP server from the System…

Building a TKG Cluster in vSphere with Kubernetes

Now that we have our vSphere with Kubernetes deployed, we take the next logical step in this post and deploy a Tanzu Kubernetes Grid (TKG) guest cluster. [Update] Whilst guest cluster isn’t an official name for the Tanzu Kubernetes cluster, I’ll use it in this post to differentiate it from the Supervisor cluster deployed with vSphere with Kubernetes. TKG is a full CNCF certified Kubernetes distribution. It is deployed as a set of virtual machines, in accordance with a TanzuKubernetesCluster manifest which we will look at later. The OS and K8s distribution is also specified in the manifest. There may…

A first look at vSphere with Kubernetes in action

In my previous post on VCF 4.0, we looked at the steps involved in deploying vSphere with Kubernetes in a Workload Domain (WLD). When we completed that step, we had rolled out the Supervisor Control Plane VMs, and installed the Spherelet components which allows our ESXi hosts to behave as Kubernetes worker nodes. Let’s now take a closer look at that configuration, and I will show you a few simple Kubernetes operations to get you started on the Supervisor Cluster in vSphere with Kubernetes. Disclaimer: “Like my earlier posts, I want to be clear, this post is based on a…
