Quick Tip - Install Metallb as service load balancer with Tanzu Community Edition (TCE)

by // 1 Comment

There have been a few questions in the community asking about service load balancer options when using Tanzu Community Edition (TCE). Out of the box, TCE does support NSX Advanced Load Balancer (NSX-ALB), but most folks will probably not have access to NSX-ALB or the resources to set that up. As an alternative, either kube-vip and metallb can be used and they are completely free and easy to setup.

I personally have used metallb before and I definitely recommend it for its ease of use and setup. You can find the instructions below on setting up metallb with TCE along with a sample kubernetes (k8s) application to verify its functionality.

Note: Scott Rosenberg is also doing some interesting stuff with Carvel that would enable easy deployment of kube-vip and metallb in TCE. I am hoping I will get some time to take a look at this setup as I think this would be great user experience for TCE just like you can install other k8s applications.

Minimum vSphere edition & features for Tanzu Community Edition (TCE)

by // 7 Comments

There have been a number of questions that have been raised by the community regarding the specific vSphere features and/or editions that is needed to deploy Tanzu Community Edition (TCE). I honestly thought I knew the requirements quite well myself but when it came to specific vSphere Editions, it made me second guess on what features TCE actually required for functionality.

I decided to deploy a brand new setup using the latest vSphere 7.0 Update 3 (vCenter Server and ESXi) release, which was all deployed onto a single 11th Gen Intel NUC. Below are my findings which I will share back with TCE folks and enhance our documentation. Ultimately, you just need access to a vCenter Server that is managing an ESXi host which can be a standalone host or one that is within a vSphere Cluster. Hopefully this will be helpful for anyone that wishes to get started.

vSphere Version:

  • As the official TCE documentation states, vSphere 6.7 Update 3 or newer is needed and this is primarily because that is the initial release that incorporates our vSphere CSI driver

vSphere Edition (minimum):

  • vCenter Standard and vSphere Standard
  • vCenter Essentials and vSphere Essentials Plus

Note: I did not have access to a vSphere Essential license but I am pretty confident it should also work.

vSphere Features:

  • Both vSphere HA and DRS is NOT required

Quick Tip - Workaround for x509: certificate signed by unknown authority when using Tanzu Community Edition (TCE) on Windows

by // 4 Comments

Tanzu Community Edition (TCE) was just launched a few days ago and a lot of folks are kicking the tires. Just yesterday, I saw that we had already surpassed over 2K+ downloads, a huge achievement for the TCE team and lots of positive feedback like this and this.

I had a comment today from a reader who ran into the following error when using TCE for Windows:

Downloading TKG compatibility file from 'projects.registry.vmware.com/tkg/framework-zshippable/tkg-compatibility'
Error: unable to create Tanzu Standalone Cluster client
Cause: unable to ensure prerequisites: unable to ensure tkg BOM file: failed to download TKG compatibility file from the registry: failed to list TKG compatibility image tags: Get "https://projects.registry.vmware.com/v2/": x509: certificate signed by unknown authority

I immediately knew the issue as I ran into this myself a couple of days ago and started to look in TCE Github Issues.
