One of the most interesting announcements for me at VMware Explore 2022 was around the introduction of vSphere Zones. This feature, when it becomes available with vSphere 8.0, enables vSphere with Tanzu deployments to be rolled out across geographically dispersed vSphere clusters placed in separate racks in a single physical datacenter, as per the release notes. This provides an extra level of availability that wasn’t previously possible. This extra availability is not just for the Supervisor Cluster, but also for the Tanzu Kubernetes clusters deployed by the TKG service. And indeed, it provides additional availability to the applications running on…
Many readers with an interest in Kubernetes, and particularly Tanzu, will be well aware that there is no embedded Load Balancer service provider available in vSphere. Instead, the Load Balancer service needs to be provided through an external source. VMware supports a number of different mechanisms to provide such a service for Tanzu. One of the more popular providers is the NSX Advanced Load Balancer, formerly Avi Vantage. In the most recent release, version 22.1.1, some of the setup steps have changed significantly. In this post, I will highlight the setup of the new NSX ALB. Important: NSX ALB v22.1.1…
I’m delighted to report that my new book, Kubernetes for vSphere Administrators, is now available. It is available in both paper form and as a Kindle eBook. Links to both are provided below. The links above direct you to Amazon.com. However the book is available in other Amazon marketplaces as well. (If you can’t see the text+images above, this is a link to the paper book and this is a link to the eBook.) I hope readers of this book find it useful. I would be delighted to receive feedback and reviews on the content.
Last year, I wrote a post about my 16 years at VMware. As part of that milestone, VMware has kindly granted me 4 weeks of respite. I’m not one for sitting on a beach for hours on end. Apart from some jobs around the house (that I have been putting off for far too long), and some short breaks, I wanted to use this time to finish a long-term project that I have been working on. The project is a new book called Kubernetes for vSphere Administrators. I thought I’d give you all a quick look at the cover and…
This post continues to build on some of the other work already done on vSphere with Tanzu and NSX-T. In previous posts, we’ve seen how to setup NSX-T so it can be used by vSphere with Tanzu. The steps to install NSX-T Manager and prepare ESXi hosts was looked at in part 1. We saw how to set up an NSX-T Edge in part 2. Then in part 3, the steps to create a tier-0 gateway with BGP for dynamic routing shown. Most recently, the various NSX-T objects and services that are configured when the Supervisor cluster is deployed were…
I have been spending a lot of time recently on vSphere with Tanzu and NSX-T. One of the tasks that I want to do is perform a network trace from a pod running on a TKG worker node. This will be for a future post. However, before running the trace, I need to secure shell (ssh) onto a TKG worker node in order to run the traceroute. This is more challenging with NSX-T compared to using vSphere networking. The reason why is because NSX-T provides “internal” network segments for the nodes which sit behind a tier-1 and tier-0 gateway. To…
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…
