vSphere CSI v2.2 – Online Volume Expansion

The vSphere CSI driver version 2.2 has just released. One of the features I was looking forward to in this release is the inclusion of Online Volume Expansion. While volume expansion was in earlier releases, it was always an offline operation. In other words, you have to detach the volume from the pod, grow it, and then attach it back when the expand operation completed. In this version, there is no need to remove the Pod. In this short post, I’ll show a quick demonstration of how it is done. Requirements Note: This feature requires vSphere 7.0 Update 2 (U2).…

VCP to vSphere CSI Migration in Kubernetes

When VMware first introduced support for Kubernetes, our first storage driver was the VCP, the in-tree vSphere Cloud Provider. Some might remember that this driver was referred to as Project Hatchway back in the day. This in-tree driver allows Kubernetes to consume vSphere storage for persistent volumes. One of draw-backs to the in-tree driver approach was that every storage vendor had to include their own driver in each Kubernetes distribution, which ballooned the core Kubernetes code and made maintenance difficult. Another drawback of this approach was that vendors typically had to wait for a new version of Kubernetes to release…

First steps with the NSX Advanced Load Balancer (NSX ALB)

As part of the vSphere 7.0 Update 2 (U2) launch, VMware now provides another Load Balancer option for vSphere with Tanzu. This new Load Balancer, built on Avi Networks technology (and previously known as Avi Vantage), provides another production-ready load balancer option for your vSphere with Tanzu deployments. This Load Balancer, now called the NSX Advanced Load balancer, or NSX ALB for short, will provide Virtual IP addresses (VIPs) for the Supervisor Control Plane API server, the TKG (guest) clusters API server and any Kubernetes applications that require a service of type Load Balancer. In this post, I will go…

vSAN DPp – MinIO Object Store Supervisor Service [Video]

In this short video, I will demonstrate a new feature of vSphere with Tanzu, namely the vSAN Data Persistence platform. In this demo, we will show how easy it is to deploy a Supervisor Service using vSAN DPp. The service that we are deploying is MinIO, a provider of on-premises S3 Object Stores. We will see how to enable the Service, and then how to provision a dedicated S3 Object Store to a particular Namespace with vSphere with Tanzu. This means that a developer or a team of developers using a particular namespace can have their own dedicated S3 Object…

vSphere with Tanzu stateful application backup/restore using Velero vSphere Operator

Recently I wrote about our new Velero vSphere Operator. This new functionality, launched with VMware Cloud Foundation (VCF) 4.2, enables administrators to backup and restore objects in their vSphere with Tanzu namespaces. In my previous post, I showed how we could use the Velero vSphere Operator to backup and restore a stateless application (the example used was an Nginx deployment) to and from an S3 Object Store bucket. The S3 object store and bucket was provided by the Minio Operator that is also available in VCF 4.2 as part of the vSAN Data Persistent platform (DPp) offering. In this post,…

VCF 4.1.0.1 Update to VCF 4.2 – Step by Step

VMware recently announced the release of VMware Cloud Foundation (VCF) version 4.2. I was particular interested in this release as it allows me to try out the new vSAN Data Persistence platform (DPp). My good pal Myles has an excellent introduction to DPp here  and I plan to create a number of posts on it going forward. My VCF 4.1.0.1 environment is what we call a Consolidated Architecture , meaning that both the management domain and workload domain run on the same infrastructure. The primary application that I run in this environment is VCF with Tanzu (vSphere with Tanzu on…

TKG & vSAN File Service for RWX (Read-Write-Many) Volumes

A common question I get in relation to VMware Tanzu Kubernetes Grid  (TKG) is whether or not it supports vSAN File Service, and specifically the read-write-many (RWX) feature for container volumes. To address this question, we need to make a distinction into how TKG is being provisioned. There is the multi-cloud version of TKG, which can run on vSphere, AWS or Azure, and are deployed from a TKG manager. Then there is the embedded TKG edition where ‘workload clusters’ are deployed in Namespaces via vSphere with Tanzu / VCF with Tanzu. To answer the question about whether or not TKG…
