NSX-T and vSphere with Tanzu revisited (part 3 of 3)

The steps to deploy NSX-T Manager, create a Compute Manager and configuring NSX on the ESXi hosts were described in part 1 of this series of posts. The steps¬† to create an NSX-T Edge cluster were outlined in part 2. In this part 3 post, we will look at the final step in preparing an NSX-T environment for vSphere with Tanzu, and that is the creation and configuring of a tier-0 gateway. Networks that are created for Kubernetes workloads in vSphere with Tanzu will connect to this tier-0 gateway and subsequently allow external connectivity to the TKG clusters, e.g. developers…

NSX-T and vSphere with Tanzu revisited (Part 2 of 3)

In part 1 of 3, the steps on how to add vCenter server as the NSX Compute Manager and how to configure the ESXi hosts as host transport nodes were completed. In this part 2 of the series, the creation of an NSX Edge cluster is described. Once again, the end goal of this post is to have an NSX-T configuration that can be leveraged by vSphere with Tanzu. When this part is complete, the overlay network should extend to include the Edge nodes for east-west traffic. The Edge nodes will also be configured to have uplinks to allow for…

NSX-T and vSphere with Tanzu revisited (Part 1 of 3)

It is quite some time since I looked at deploying NSX-T, VMware’s unified networking platform. The reason for this is that VCF, VMware Cloud Foundation, takes care of the deployment and configuration of NSX-T automatically through the SDDC Manager. However, I wanted to revisit it and do it the hard way, just to re-educate myself on the steps involved. The goal is to have an NSX-T configuration that can be leveraged by vSphere with Tanzu. Since this is rather a lengthy process, I will divide it up into 3 separate posts. The first will focus on the configuration ESXi hosts…

Kubernetes, vSAN Stretched Cluster with CSI driver v2.5.1

In this post, we will look at a relatively new announcement around support for vanilla or upstream Kubernetes clusters, vSAN stretched cluster and the vSphere CSI driver. There are a number of updates around this recently, so I want to highlight a few observations before we get into the deployment. First of all, it is important to highlight that a vSAN Stretched Cluster can have at most 2 fault domains. These are the data sites. While there is a requirement for a third site for the witness, the witness site does not store any application data. Thus all of the…

Announcing vSphere CSI driver v2.5 metrics for Prometheus monitoring

This post will look at another new feature that has been added to the vSphere CSI driver v2.5. This feature enables the exposing of CSI metrics so that they can be collected by Prometheus and stored as time series data. Using the information captured in Prometheus, we can build Grafana dashboards which makes is easy to monitor the health and stability of the CSI driver. Kudos to one of our vSphere CSI driver engineers, Liping Xue, who did a great write-up on how to test this feature, and who’s content I relied on heavily to create this post. In the…

CSI Snapshots in action (vSphere CSI 2.5) [Video]

I have created a short video to demonstrate the new CSI snapshots feature in vSphere CSI driver version 2.5. This demo begins with an existing Pod + PVC/PV volume on vSphere storage, take a snapshot of the volume, then restore it to a new PVC. This new volume will then be mounted by a new Pod, and we will examine it to see if the data was successfully captured and restored. The manifests demonstrated in this video are available for download on this GitHub repository. Hope you find it useful.

Announcing vSphere CSI driver v2.5 support for CSI snapshots

I’m delighted to announce that VMware has just released a new version of the vSphere CSI driver for Kubernetes. The full release notes are available here. This 2.5 version now has support for CSI snapshots, a feature that many customers and partners have been waiting for. This features enables snapshots to be taken of block-based persistent volumes, as well as the ability to restore snapshots to persistent volumes. Those of you familiar with the CSI driver will notice two additional Kubernetes components to enable snapshot support. The first is a new snapshot controller. When a snapshot is created, two new…
