VMUG Recording – Understanding Data Protection for your VMware Tanzu Container Workloads

Kubernetes, , , ,

As part of my virtual VMUG tour, I submitted a session to the VMUG call for papers covering the subject of Data Protection for Tanzu Kubernetes workloads. (Most of this will apply for any Kubernetes environments).

This was picked up by Erik at the Belgium VMUG for their UserCon in June 2021. After the session the videos remain available on demand for a short time, but there were no plans to upload this for everyone. So thank you to Michael Cade, whom offered to host this session for all on the Cloud Native Data Management – YouTube Channel.

In the below session I cover the following areas;

  • ​What kind of data protection do you need?
  • ​Velero
    • The open source data protection project from VMware
  • ​Tanzu Mission Control
    • The Kubernetes fleet management platform that utilizes Velero from VMware.
  • ​3rd Party Options
    • A nod to the 3rd party ecosystem that offer enterprise Data Protection and Management software such as;
      • Kasten
      • PortWorx

There is even a quick technical demo in there, with a little technical hiccup I had to style out!

Deploying Tanzu Kubernetes Grid to AWS fails with ‘InstanceProvisionFailed’

VMware, Kubernetes, , , ,
The issue

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'
The Cause

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’ →

Understanding the VMware Tanzu Kubernetes Terminology

VMware, , , , , , , ,

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.

Twitter thread asking about TKGm and TKGs

First, we’ll break down the high level names and products. Then move into Tanzu Kubernetes products.

What is VMware Tanzu?

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.

What products are covered by the VMware Tanzu brand?

Kubestr – Open-Source Kubernetes Storage benchmarking tool

Kubernetes, , , , ,

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.

What is Kubestr?

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.

Getting started with Kubestr

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.

kubestr download and extract

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.

kubestr first run

Green Box – we have our initial checks.

  • Kubernetes version
  • RBAC check
  • Kubernetes Aggregated layer check

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 →
