Safekeeping – a useful tool for interacting with First Class Disks/Improved Virtual Disks

I have been doing quite a bit of work on First Class Disks (FCD), also known as Improved Virtual Disks (IVD) over the past number of months. One tool that has been extremely useful in improving my understanding of FCDs has been safekeeping, a tool developed by Max Daneri of VMware and which is now […]

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 […]

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 […]

Kubernetes Storage on vSphere 101 – Failure Scenarios

We have looked at quite a few scenarios when Kubernetes is running on vSphere, and what that means for storage. We looked at PVs, PVC, PODs, Storage Classes, Deployments and ReplicaSets, and most recently we looked at StatefulSets. In a few of the posts we looked at some controlled failures, for example, when we deleted […]

A primer on First Class Disks/Improved Virtual Disks

A First Class Disk (FCD), also referred to as Improved Virtual Disk (IVDs), is one of the more recent features in vSphere that may have escaped your notice. FCDs were created to address a particular gap that we have in vSphere at this time. We are well aware that within a vSphere environment, it is […]

Validating overlay network when docker swarm running on Centos VMs on vSphere

I got a chance to revisit my docker swarm deployment this week after a bit of a break. I was a little curious about my setup because when I spoke to some of our ‘Project Hatchway‘ engineers, I was told that I should be able to launch a single instance of Nginx in Docker Swarm […]

Project Hatchway hitting the mainstream – persistent storage for containers

Regular readers will be aware that I “dabble” from time to time in the world of Cloud Native Apps. For me, a lot of this dabbling is trying to figure out how I can go about providing persistent storage to container based applications. Typically this in the shape of container volumes that are carved out […]
