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:

Getting started with VCF 4.0 Part 2 – Commission hosts, Create Workload Domain, Deploy NSX-T Edge

Now that a VCF 4.0 Management Domain has been deployed, we can move onto creating our very first VCF 4.0 Virtual Infrastructure Workload Domain (VI WLD). We will require a VI WLD with an NSX-T Edge cluster before we can deploy Kubernetes on vSphere (formerly known as Project Pacific). Not too much has changed in the WLD creation workflow since version 3.9. We still have to commission ESXi hosts before we can create the WLD. But something different to previous versions of VCF is that today in VCF 4.0 we can automatically provision NSX-T Edge clusters from SDDC Manager to…

Getting started with VMware Cloud Foundation (VCF) 4.0

On March 10th, VMware announced a range of new updated products and features. One of these was VMware Cloud Foundation (VCF) version 4.0. In the following series of blogs, I am going to show you the steps to deploy VCF 4.0. We will begin with the deployment of a Management Domain. Once this is complete, we will commission some additional hosts and build our first workload domain (WLD). After that, we will deploy the latest version of NSX-T Edge Cluster to our Workload Domain. The great news here is that this part has now been automated in VCF 4.0. Finally,…

Kubernetes on vSphere 101 – Ingress

As I was researching content for the 101 series, I came across the concept of an Ingress. As I hadn’t come across it before, I wanted to do a little more research on what it actually did. It seems that in some ways, they achieve the same function as a Load Balancer in so far as they provide a mean of allowing external traffic into your cluster. But they are significantly different in how they do this. If we take the Load Balancer service type first, then for every service that is exposed via a Load Balancer, a unique external…

A first look at vRealize Network Insight for Kubernetes

Regular readers will know that I have been spending quite a bit of time recently looking at Kubernetes running on vSphere. I’ve written a number of posts on the storage side of things, which you can read here as part of my 101 series. I also posted about how you can setup vRealize Operations Manager 7.5 and add the Management Pack for Container Monitoring. This provide some really good dashboards for examining the state of your K8s clusters, as well as detailed breakdowns into K8s node VM health and performance (CPU, Memory, DIsk IO). Not only that, but you can…

Kubernetes on vSphere 101 – Services

This will be last article in the 101 series, as I think I have covered off most of the introductory storage related items at this point. One object that came up time and again during the series was services. While not specifically a storage item, it is a fundamental building block of Kubernetes applications. In the 101 series, we came across a “headless” service with the Cassandra StatefulSet demo. This was where service type ClusterIP was set to None. When we started to look at ReadWriteMany volumes, we used NFS to demonstrate these volumes in action. In the first NFS…

Kubernetes Storage on vSphere 101 – NFS revisited

In my most recent 101 post on ReadWriteMany volumes, I shared an example whereby we created an NFS server in a Pod which automatically exported a File Share. We then mounted the File Share to multiple NFS client Pods deployed in the same namespace. We saw how multiple Pods were able to write to the same ReadWriteMany volume, which was the purpose of the exercise. I received a few questions on the back on that post relating to the use of Services. In particular, could an external NFS client, even one outside of the K8s cluster, access a volume from…
