Is vSphere with Kubernetes available for evaluation? 

07.14.2020 by William Lam // 1 Comment

Yes. Given the frequency that this question has come up, I thought it would be useful to share some more details on how you can start playing with the new vSphere with Kubernetes (K8s) capability which was introduced as part of the vSphere 7.0 release. vSphere w/K8s requires NSX-T and although vSphere (ESXi and vCenter Server Appliance) has supported a 60 day evaluation period, NSX-T historically did not support any self-service evaluation. In addition, there were also some confusion in how vSphere w/K8s was bundled today from a packaging standpoint which is offered as part of the VMware Cloud Foundation (VCF) 4.0 SKU.

Putting aside the pricing and packaging aspects, customers can indeed evaluate vSphere w/K8s using one of the following two options below:

Option 1: 60 Day Eval

Sign up for the vSphere 7.0 (ESXi & VCSA) evaluation (https://my.vmware.com/en/web/vmware/evalcenter?p=vsphere-eval-7) and NSX-T 3.0 evaluation (https://my.vmware.com/web/vmware/evalcenter?p=nsx-t-eval). After signing up you will receive evaluation keys that can be used when setting up vSphere w/K8s. If you want to quickly go from 0 to Kubernetes, be sure to check out my vSphere with K8s Automation Lab Deployment which can give you a running environment in under 30min!

Option 2: 365 Day Eval

Sign up for VMUG Advantage which includes VMUGEval that provides licenses for vSphere 7.0, NSX-T 3.0, VCF 4.0 and many other VMware products for an entire year for non-production usage. After signing up you will receive license keys that will be valid for 1 year which can then be used when setting up vSphere w/K8s. With VMUG Advantage, you can consume vSphere w/K8s the "manual" method, using my vSphere with K8s Automation Lab Deployment or using SDDC Manager which is part of VCF 4.0 to automatically deployed the required SDDC infrastructure so that can then enable vSphere w/K8s.

Here is a screenshot of my vSphere w/K8s environment which was deployed using my Sphere with K8s Automation Lab Deployment script and using the evaluation keys which I had just signed up!

Option 3: Infinite Day Eval

VMware Hands-on-Lab is another great option which is completely free and you only need a web browser! You can check out HOL-2113-01-SDC for more details.

Admin account for embedded Harbor registry in vSphere with Kubernetes

06.09.2020 by William Lam // 3 Comments

After setting up a vSphere with Kubernetes Cluster, customers have the option of enabling a built-in private container registry that can be used with the Supervisor Cluster. This private container registry uses the popular Opensource Harbor solution which is also a Cloud Native Computing Foundation (CNCF) project.


Although this is a convenient capability, one thing to be aware of is that the embedded Harbor registry is limited in functionality compared to a standalone Harbor deployment and this is by design. When logging into Harbor with your vCenter SSO user, you will be able to do perform basic operations such as pushing and pulling images from this registry. For customers that require additional functionality from Harbor, it is recommended that you setup an external Harbor instance which can also be used as a common registry for both the Supervisor Cluster as well any Tanzu Kubernetes Grid (TKG) Clusters that you may provision.

With that said, I have heard from a few folks who were interested in accessing the Harbor UI using the "admin" account, mostly from an exploration standpoint. The admin credentials for Harbor are dynamically generated each time the service is enabled and it is stored as a K8s secret within the Supervisor Cluster. This means the admin password is unique for each environment and the instructions below will show you how to obtain the credentials.

UPDATE (12/16/20) - I was informed by Engineering the ability to read K8s secrets was actually a bug and this has since been fixed in the latest release of vSphere with Tanzu. If you need the harbor credentials, you will need to directly login to the Supervisor Cluster from the VCSA (instructions have been updated below) to retrieve this information.

Disclaimer: This is not officially supported by VMware and the behaviors described below could change in the future without notice.

Interesting Kubernetes application demos

06.08.2020 by William Lam // 3 Comments

I am always on the lookout for cool and interesting demos to deploy, especially with some of the work I have been doing lately with vSphere with Kubernetes (K8s) and Tanzu Kubernetes Grid (TKG). I am sure many of you have probably seen the basic wordpress demos which seems to be the typical "Hello World" app for K8s and having something more compelling not only makes the demo more interesting but it can also help folks better understand how a modern applications can be built, deployed and run.

Below is a list of of the K8s demo applications that I have come across as part of my exploration and by no means is this an exhaustive list. I have been able to successfully deploy these applications running on the latest version of K8s (1.17 and 1.18) as I did come across other demos which did not work or I had issues setting up. If there are other K8s demos that folks have used, feel free to leave a comment and I will update the blog post after doing some basic testing.

For those of you who may not have a K8s environment and is running either vSphere 6.7 Update 3 or have access to a VMware Cloud on AWS SDDC, you can easily setup a TKG Cluster in under 30 minutes leveraging my TKG Demo Appliance Fling.
