NSX-T and vSphere with Tanzu – automatically created network objects and services

In my most recent posts, the steps to get NSX-T to a point where it is ready for vSphere with Tanzu are examined. A three-part blog series describes the NSX-T setup process for vSphere with Tanzu – see part 1, part 2, and part 3. In this post, we will take a look ‘under the covers’. I will look at the network objects and services that vSphere with Tanzu automatically builds in NSX-T. As per these previous configuration steps, a number of NSX-T system objects are setup, such as Compute Manager and Edge Cluster. Some network objects must also be…

vSphere with Tanzu and Tanzu Mission Control integration [Videos]

I created a few short videos to show the integration between Tanzu Mission Control (TMC) and vSphere with Tanzu. In the first demonstration, I show the steps involved in registering the vSphere with Tanzu Supervisor Cluster with Tanzu Mission Control. Basically, it involves retrieving a manifest from TMC, and deploying it to the Supervisor. In the second demo, I show how Tanzu Mission Control can be used to easily deploy Tanzu Kubernetes (TKG) workload clusters to vSphere with Tanzu once the Supervisor Cluster has been registered. Of course, once TMC is managing your cluster, all sorts of additional features are…

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…
