I had the pleasure of presenting this Kubernetes 101 session to the Veeam Community thanks to my work as part of their Veeam Vanguards program, and a special thank you to Michael Cade who co-presented with me!
In this session we cover the following with technical details included:

When deploying Tanzu Kubernetes Grid to AWS, the deployment was failing with the following output:
unable to set up management cluster, : unable to wait for cluster and get the cluster kubeconfig: error waiting for cluster to be provisioned (this may take a few minutes): cluster creation failed, reason:'InstanceProvisionFailed @ Machine/tkg-aws-mgmt-control-plane-dqb4v', message:'1 of 2 completed'
When we reviewed the CAPA logs (Cluster API AWS provider) we found the following errors logged: Continue reading Deploying Tanzu Kubernetes Grid to AWS fails with ‘InstanceProvisionFailed’
It’s not uncommon for me to see the question asking for an explanation of VMware Tanzu Kubernetes terminology and differences between similar named products. As per the below tweet. This is my blog post to address the Tanzu Kubernetes terminology and use.
First, we’ll break down the high level names and products. Then move into Tanzu Kubernetes products.
VMware Tanzu is a brand name covering VMware’s modern applications suite of products, just like vRealize is the suite name for VMware’s cloud management products.

Kubernetes is a platform which is starting to lose the need for introduction in most settings. However, it still can be a complex beast to get to grips with, and getting your infrastructure components configured correctly is key to providing a successful Kubernetes environment for your applications.
One of these such areas is storage.
With your Kubernetes platform, you need to ensure a correct storage configuration, and benchmark your storage performance, like you would with any other platform. Then test the container storage features such as snapshots of the persistent volumes.
The configuration for each vendor when integrating with Kubernetes will be different, but the outcomes should be the same.
Enter Kubestr, the Open-Source project tool from Kasten by Veeam, designed to help with ensuring your storage is configured correctly, help you benchmark the performance and test features such as snapshots.
Simply Download Kubestr for the platform you wish to run the tool from. For me I’ll be running it from my Mac OS X machine, which has connectivity to my Kubernetes platform (AWS EKS, I used this blog to create it).
I extracted the zip file and have the Kubestr command line tool available in the output folder.
Running the tool for the first time will run some tests and output a number of useful items of information on how we can use the tool. Which I will start to breakdown as we continue.
For Kubestr to run, it will use the active context in your kubectl configuration file.
Green Box – we have our initial checks.
Then we have the details from our available storage provisioners that are installed for our cluster. You can see what I have two installed. Continue reading Kubestr – Open-Source Kubernetes Storage benchmarking tool
