The VMware vSphere 8 Default SSL/TLS Cipher Suites have recieved an update from the vSphere 7 defaults and got rid of some legacy stuff. Still, there might be a compliance requirement to even reduce this list. The goal of this post is to get rid of everything that is SHA1 based (e.g. AES256-SHA) on the vCenter...
A collegue approached me with a customer request that concerned the NSX-T APIs. More specifically the customer is already using the NSX-T API in management mode but didn’t find the equivalent in the policy API. Doing my own research, I also failed to find the API right away.

Hey, I surely did this just last year and not in 2020, didn’t I? Well, the Linux Foundation said otherwise and here is my re-take experience. I cleared the CKA exam with a score of...

TL,DR: GitHub Repo for TCE Demo appliance Motivation# I was quite excited when VMware released Tanzu Community Edition. It is a free and open source distribution of VMware Tanzu, featuring Cluster-API and other amazing stuff. It was just what I needed to further expand my Kubernetes-fu and it is suitable sized for any...
Note: If you face this problem in a production environment you should reach out to VMware Global Support at this point. This is not an official guide. And even if you use it in non-prod, please make a backup before any changes. These steps are a mix and match from slack threads, engineering PRs etc that I compiled. So,...
While rebuilding my lab from scratch with vSphere 7.0 U3c NSX Advanced (AVI) Load Balancer 21.1.3 I hit a situation where my TKGS installation would not continue with an error, it was stuck for hours: The control plane VM <ID> was unable to authenticate to the load balancer (Avi - https://<NSX ALB Controler...
Many thanks to Darius Davis from our engineering team who set me up on the solution. This morning I “just wanted to spin up a container quickly”. Having a recent version of VMware workstation already on my computer, using vctl was my preferred choice (In case you missed the blog). Problem# My initial plans came to a...
