Finding VMDK path from PV VolumeHandle

I’ve been looking at ways in which we could query the mappings of objects between the Kubernetes layer and the vSphere layer. One thing that I really wanted to figure out is if I have the VolumeHandle from the Persistent Volume in Kubernetes, could I easily find the datastore and path using PowerCLI. It looks like I can. Let’s begin with a look at the Persistent Volume or PV  for short. Note that this is a Kubernetes cluster that is using the new vSphere CSI driver. 

Moving a Stateful App from VCP to CSI based Kubernetes cluster using Velero

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.…

Two short video demos – CNS and Velero 1.1

I put together a few short (7 – 8 minute) videos to show off some new functionality that we’ve recently added in vSphere 6.7U3, as well as our new Velero v1.1 in action. The first video is on CNS, the VMware Cloud Native Storage feature which we included in vSphere 6.7U3. This demonstration involves the deployment of a Cassandra database on Kubernetes, which incidentally uses the new CSI (Container Storage Interface) driver for persistent volumes. Once the application is deployed, we can see the characteristics of the volumes bubbled up in vSphere. We also see how using CNS, we can…

Introducing vSphere Cloud Native Storage (CNS)

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…

My highlights from KubeCon and CloudNativeCon, Day #3, Europe 2019

Today is the final day of KubeCon/CloudNativeCon here in Barcelona. I missed the morning keynotes as I was meeting with some of our DELL Technologies colleagues based here is Barcelona. They are working on something that is very cool, and I hope I’ll be able to share more with you later this year. Anyway, once at the event, these are some of the sessions I attended. I wanted to try and catch a few presentations that were not storage orientated today, simply to get a better idea of what is happening in the broader K8s community. The first of these…

My highlights from KubeCon and CloudNativeCon, Day #2, Europe 2019

Day 2 at KubeCon/CloudNativeCon Europe 2019 started with another set of keynotes. Bryan Liles started with a theme that Kubernetes is a platform for creating platforms. Kubernetes is not an end in itself, it is not a destination but it is a means of building something for future success. This was a good way to introduce us to some of the customer keynotes that were to follow. Bryan first introduced David Xia from Spotify. David shared with us his story of how Spotify deleted not one, but two of their three Kubernetes clusters during a migration. It was a pretty…

My highlights from KubeCon and CloudNativeCon, Day #1, Europe 2019

This year, I have once again been fortunate enough to attend KubeCon and CloudNativeCon Europe, which is being held in Barcelona. This is my second such conference, having attended last years European event in Copenhagen. I was very interested in seeing how things have progressed, especially in the cloud native storage space. The morning started with the usual set of keynotes. Dan Kohn and Cheryl Hung filled us in on what is happening in the Cloud Native Computing Foundation (CNCF) space, sharing details about the increase in membership and contributors since the last conference. Of note, there are 7700 attendees…
