Tanzu Kubernetes Grid (TKG) Demo Appliance for VMC and vSphere

by // 8 Comments

As some of you can probably tell from my recent Twitter updates and blog posts (here and here) that I have been spending some time lately with both vSphere with Kubernetes and Tanzu Kubernetes Grid (TKG). Like many of you in the community, I am still pretty new to Kubernetes (K8s) and I am still learning about what it has to offer both from an infrastructure standpoint but more importantly how it can be used to deliver new and modern applications. I am also very lucky to be part of the the VMware Event Broker Appliance Open Source Fling project which builds and runs on top K8s and this project has allowed me to really get hands on which is how I learn best.

A couple of months back I was asked to put together a workshop to demonstrate how to deploy TKG Clusters running on VMware Cloud on AWS (VMC) and while developing the workshop, I thought it would be really cool if I could make it even easier for anyone that is brand new to K8s to quickly get started with TKG. I wanted to have a solution that can literally be dropped into any supported vSphere-based environment with basic networking to go from Zero to Kubernetes in less than 30 minutes!

Enter the Demo Appliance for Tanzu Kubernetes Grid (TKG) Fling

A Virtual Appliance that pre-bundles all required dependencies to help customers in learning and deploying standalone Tanzu Kubernetes Grid (TKG) clusters running on either VMware Cloud on AWS and/or vSphere 6.7 Update 3 environment for Proof of Concept, Demo and Dev/Test purposes. This appliance will enable you to quickly go from zero to Kubernetes in less than 30 minutes with just an SSH client and a web browser!


In addition to the appliance, I have also put together a step by step workshop-style guide which not only walks you through in deploying your first TKG Cluster but also provide some example demos and references which you can explore further. Below are some of the highlights of the Demo Appliance for TKG:

Forwarding VMC Events to AWS Lambda/CloudWatch using Log Intelligence Webhook

by // Leave a Comment

In my previous post, I provided an example on how customers can take advantage of Log Intelligence's Webhook capability to consume VMware Cloud on AWS (VMC) based events and extend that to other Public Cloud Services like Slack as an example to build new and interesting integrations. We took advantage of the fact that some of these Public Cloud Services either have native webhook support or have a built-in Webhook listener like IFTTT which in turn can support other services which may not have native Webhook support.

However, customers can also build their own Webhook listener, which is nothing more than being able to POST to an API endpoint with a pre-defined JSON payload. In fact, this would be needed for any on-premises integration if the solution does not support webhooks.

For VMC customers who currently consume AWS Services such as Lambda and CloudWatch, it is actually very easy to integrate these and other AWS Services directly using LINT's Webhook feature. In fact, I chose Lambda and CloudWatch as these are two of the mostly frequently asked integration points. At our recent VMC Customer Summit, which took place last month, I had built a demo based on an actual customer use case for sending specific VMC Events from LINT to Cloud Watch as that was their tool of choice for auditing purpose.

I decided to make use of Lambda as it allowed me to quickly integrate with CloudWatch and I could also show how lambda integration would work given the number of customers asking. Ultimately, Lambda also enabled me to easily build a Webhook listener to process the LINT Webhook by simply front-ending the Lambda function with an AWS API Gateway, which was super easy to setup and use.

Forwarding VMC Events to Slack using Log Intelligence Webhook

by // Leave a Comment

VMware Log Intelligence (LINT) is a public VMware Cloud Service that is available to all VMware Cloud on AWS (VMC) customers. LINT provides customers with a unified view of their SDDC infrastructure including vSphere, NSX and vSAN from a logging standpoint and LINT can also be used with an on-premises deployment. The LINT team recently published a nice overview here, which I highly recommend a read.

One really interesting capability of LINT is the alert and notification feature, which includes UI and email, but what really stood out to me with this feature is that you can also trigger a Webhook! This means you can literally integrate with any external system including public cloud services that can receive or process a Webhook. Some examples can include publishing to a specific Slack channel, sending an SMS to your SRE team, an alert in PagerDuty or even calling an AWS Lambda function. The possibilities are truly endless on what you can do with a Webhook integration!

For our recent VMC Customer Summit, I thought it would be really cool to show off some demos on what you could do with LINT Webhooks. In this blog post, I will show you how to use the If Then This That (IFTTT) service which natively supports Webhooks and publish a specific VMC event into a Slack channel. Slack also supports native webhooks, but using IFTTT, you can apply this example to other Cloud Services that you may want to integrate with.
