The vSphere Container Storage Interface (CSI) driver is what enables Kubernetes clusters running on vSphere to provision persistent volumes on vSphere storage. This applies to both native Kubernetes clusters, and vSphere with Kubernetes. With the release of vSphere 7.0 and vSphere with Kubernetes (formerly Project Pacific) there are now a number of different flavors of the vSphere CSI driver available. [Update] Before going any further, it is worth highlighting the differences between what we term native Kubernetes and vSphere with Kubernetes. Native Kubernetes has many flavors, such as VMware Tanzu Kubernetes Grid, VMware Tanzu Kubernetes Grid Integrated (TKGI) formerly known…
After being asked about how vSphere Host Groups worked with Availability Zones in Enterprise PKS earlier this week, I decided to spend a little time setting it up in my lab and doing some testing to make sure I could understand the feature and its behaviour. Essentially what this feature allows you to do is to make use of the vSphere Host Group feature to group a bunch of ESXi hosts together. Then as one builds Availability Zones (commonly referred to AZs) in Enterprise PKS, a Host Group can be associated with an AZ. Anything that Enterprise PKS deploys to…
I was very pleased last week, as I managed to get a bunch of metrics sent from my Kubernetes cluster into Wavefront by chaining proxies together. I was successfully able to see my cluster’s Kube-state Metrics and Kubernetes Collector Metrics in Wavefront. However, on closer inspection, I noticed that a number of the built-in Wavefront Kubernetes dashboards were not being populated (Kubernetes Metrics and Kubernetes Metrics by Namespace), and then I found a number of errors in the Wavefront collector logs in my deployment. This post will describe what these errors were, and how I rectified them. There were 2…
I have written about Velero a few times on this blog, but I haven’t actually looked at how you would deploy the 1.0.0 version, even though it has been available since May 2019. Someone recently reached out to me for some guidance on how to deploy it, as there are a few subtle differences between previous versions. Therefore I decided to document step-by-step how to do it, but focusing on when your Kubernetes cluster is running on vSphere. I also highlight a gotcha when using Velero to backup applications that are running on Kubernetes deployed via Enterprise PKS, Pivotal Container…
Regular readers will be aware that I have been looking at various tools that will allow for the management and monitoring of Kubernetes running on vSphere. In the past, we’ve looked at the vRealize Operations Management Pack for Container Monitoring and vRealize Network Insight for Kubernetes. One of the other VMware products that I really wanted to try out is Wavefront. Wavefront is pretty neat as it has around 200+ pre-built integrations and dashboards. This makes it extremely easy to ingest and visualize performance data. My main issue with getting this up and running is that my Kubernetes cluster (running…
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…
The vROps Management Pack for Container Monitoring is something that I had been meaning to install and configure for a while now, but I just haven’t had a chance until very recently. If you didn’t know. VMware’s vRealize Operations has a Management Pack for Container Monitoring. This includes adapters for both the Pivotal Container Service (PKS) as well as Kubernetes. In my environment I had already deployed PKS which I was then using for deploying my Kubernetes clusters. I found the official documentation a little light on what exact information was required for both the PKS Adapter and the Kubernetes…
