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.…

A first look at Velero (previously known as Ark)

Those of you who work in the cloud native space will probably be aware of VMware’s acquisition of Heptio back in December 2018. Heptio bring much expertise and a number of products to the table, one of which I was very eager to try it. This is the Heptio Velero product, previously known as Heptio Ark. Heptio Velero provides a means to back up and restore cloud native applications. Interestingly enough, they appear to be able to capture all of the deployment details, so they are able to backup the pods (compute), persistent volumes (storage) and services (networking), as well…

Setting up Nginx reverse-proxy for distributed Minio S3 deployment

I wanted to follow-up on my recent Minio S3 post with steps on how to implement a reverse-proxy using Nginx. The purpose of this is to allow an end-user to connect to a single Minio server, and have that connection be redirected in a round-robin fashion to all of my other 16 Minio servers in my Minio S3 deployment. This was surprisingly very straight-forward, and only required a handful of changes to my nginx.conf file. If you want to review the initial deployment steps, you can find these here in my original post. Let’s go through the steps to set…

Minio S3 object store deployed as a set of VMs on vSAN

Some time back, I looked at what it would take to run a container based Minio S3 object store on top of vSAN. This involved using our vSphere Docker Volume Server (aka Project Hatchway, and the details can be found here. However, I wanted to evaluate what it would take to scale out the Minio S3 object store on top of vSAN, paying particular attention to features like distribution and availability, and to examine the various data services that can be provided by both vSAN and Minio. I also wanted to take advantage of the new host-pinning feature in vSAN…
