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.

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.

Setup custom login banner when logging into a vSphere with Kubernetes Cluster

05.20.2020 by William Lam // Leave a Comment

While working on my PowerCLI module for enabling workload management for a vSphere with Kubernetes (K8s) Cluster, I came to discover a pretty cool feature that is only available when using the vSphere with K8s API to enable Workload Management on a vSphere Cluster.

As part of the enablement spec, there is a new property called login_banner. Taking a closer look, this property allows you to specify a custom message that would be displayed as part of the initial login to your vSphere with K8s Cluster using the vSphere kubectl plugin. This is similar to an SSH login banner which can be used to provide internal disclaimers and/or additional instructions for your end users.

Here is an example of what the login banner can look like. Yup, vSphere with K8s supports emojis or rather the terminal you are using to login can potentially render emojis 😀


The good news is that I have already added this feature into the new New-WorkloadManagement function and you can specify a message by adding the -LoginBanner parameter.

For those interested in rendering emojis within their banner, you can take a look at the following example and you can find the complete list of emoji unicodes here.

$LoginBanner = "

" + [char]::ConvertFromUtf32(0x1F973) + "vSphere with Kubernetes Cluster enabled by virtuallyGhetto " + [char]::ConvertFromUtf32(0x1F973) + "

"
