Since the release of the vSphere CSI driver in vSphere 6.7U3, I have had a number of requests about how we plan to migrate applications between Kubernetes clusters that are using the original in-tree vSphere Cloud Provider (VCP) and Kubernetes clusters that are built with the new vSphere CSI driver. All I can say at this point in time is that we are looking at ways to seamlessly achieve this at some point in the future, and that the Kubernetes community has a migration design in the works to move from in-tree providers to the new CSI driver as well.…
Hola! It is only a month or so to go until VMworld 2019 arrives back in Europe. Yet again, we are back in Barcelona for what promises to be a great event. I missed VMworld in San Francisco this year – too many things happening on the home front. So I’m really looking forward to getting down to Spain in early November and meeting up with everyone again. I am involved in 2 sessions in Barcelona. One of the sessions is the HCIBU Spotlight Session, HCI3551KE. I am delivering this with our SVP and GM of the Hyper-converged Infrastructure Business…
In my lab, I run a number of different flavors of Kubernetes. Some of them I deploy via kubeadm. Others I have provisioned by VMware PKS. Some of these can access the outside world, while others are secured. Sometimes it is difficult to figure out the relationship between various K8s objects – which services, endpoints, PVs and PVCs are used by different Pods or StatefulSets. In the past I have used the K8s dashboard, but more often than not, I have to start kube proxy and then run some sort of tunnel (via PuTTY or similar) in order to be…
Today at VMworld 2019, VMware announced the Tanzu portfolio. Essentially, Tanzu covers a suite of up and coming products and features which will allow our customers to Build, Run and Manage modern applications on Kubernetes, on vSphere. I’m pretty sure that this will not come as a major surprise, considering some of the acquisitions and intentions that VMware has announced recently. For example, we have already had the Heptio acquisition at the end of last year, then the Bitnami acquisition in May of this year, and more recently, we’ve seen the intent to acquire both Carbon Black and Pivotal. Heptio,…
I’m delighted to be able to share with you that, coinciding with the release of vSphere 6.7 U3, VMware have also announced Cloud Native Storage (CNS). CNS builds on the legacy of the earlier vSphere Cloud Provider (VCP) for Kubernetes, and along with a new release of the Container Storage Interface (CSI) for vSphere and Cloud Provider Interface (CPI) for vSphere, CNS aims to improve container volume management and provide deep insight into how container applications running on top of vSphere infrastructure are consuming the underlying vSphere Storage. Now, there may be a lot of unfamiliar terminology in that opening…
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…
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…
