Quick Tip - Correctly naming TKR's in Local Content Library for vSphere with Tanzu in vSphere 8

09.28.2022 by William Lam // Leave a Comment

Customers can create a Tanzu Kubernetes Releases (TKR) content library by either subscribing to VMware's online repository or by creating a local content library and manually importing the images, which can be useful for air-gapped or non-internet accessible environments.

If you automatically subscribe to VMware's online repository, the TKR images (OVF) will automatically be downloaded and will be stored with a default item name that looks like the following:


However, when creating a local content library, customers must manually import the OVF images after downloading them from VMware's online repository (https://wp-content.vmware.com/v2/latest/). During the OVF import wizard, you will notice that each TKR has the same default name called "photon-ova" and you will most likely rename it to something more useful.


Prior to vSphere 8, you could use any name and vSphere with Tanzu would not care as there is metadata associated within each TKR image that provides version that is needed when creating a Tanzu Kubernetes Grid Cluster (TKC).

I was attempting to deploy a TKC using a new TKR version, which I needed to download and import into my vSphere 8 environment and that is where I ran into a strange error:

vSphere Event-Driven Automation using Tanzu Application Platform (TAP) on Tanzu Kubernetes Grid Service

01.26.2022 by William Lam // Leave a Comment

Right before the holiday, I had spent some time exploring Tanzu Application Platform (TAP), which also recently GA'ed. TAP provides developers with an application-aware platform that focuses on making the developer experience easy for developing, building and running applications on Kubernetes.


If you are interested in a quick technical deep dive into TAP, check out this video by Scott Sisil, introducing TAP:

One of the core components of TAP is the Cloud Native Runtime (CNR), which is VMware's commercial offering of the popular open source project Knative. The VMware Event Broker Appliance (VEBA) project also makes use of Knative as our backend to provide customers with an event-driven automation solution.

Early on in the VEBA project, we knew that we wanted to develop and innovate with the community in the open but we also understood there would be users who would want an officially supported offering that they can call or file support requests when needed. Early last year, Michael Gasch, the lead architect for VEBA started to port the code from the VMware Event Router, which is the heart of VEBA into CNR's Tanzu Sources for vSphere and start unifying the two code bases. The goal is to ensure that users of the open source project VEBA will also have a consistent user experience in terms of function deployment when using the commercial offering.

As shared back in Dec, I was able to successfully deploy TAP, CNR and Sources for vSphere all running on our Tanzu Kubernetes Grid Service which includes both our on-premises offering called vSphere with Tanzu and our managed service offering called VMware Cloud with Tanzu services. For those interested, you can find the instructions below on how to deploy and configure TAP to enable vSphere event-driven automation capabilities for your infrastructure.

Cluster API BYOH Provider on Photon OS (Arm) with Tanzu Community Edition (TCE) and ESXi-Arm

11.22.2021 by William Lam // Leave a Comment

Last week I demonstrated how to take advantage of the new Kubernetes Cluster API Bring Your Own Host (BYOH) Provider with a VM running on ESXi-Arm and managed with Tanzu Community Edition (TCE). The Cluster API BYOH Provider is currently only tested and supported with an Ubuntu OS, but since the only requirements for a linux host was simply: kubeadm, kubelet and containerd, I figured it should also be possible with VMware's Photon OS which also has an Arm edition.

With a TON of trial/error and reverting snapshots, I was able to finally get Cluster API BYOH Provider to successful run on Photon OS as shared in a recent tweet.

What actually made this possible was actually the work I had done with VMware Event Broker Appliance (VEBA) project which also involves Photon OS and Kubernetes. More specifically, I had recently worked on porting VEBA from using the Docker runtime to Containerd with Kubernetes and that prior experience was invaluable while figuring out how to do this with Photon OS (Arm) which also had its own challenges. The instructions below will help setup a Photon OS (Arm) VM that can then be used with Cluster API BOYH Provider and the previous article will still need to be reference for the complete setup.
