Tanzu Kubernetes Grid GPU Integration

I recently had to demonstrate Tanzu Kubernetes Grid and its GPU integration capabilities. Developing a good use case and assembling the demo required some preliminary research.

During my research, I reached out to Jay Vyas, staff engineer at VMware, SIG Windows lead for Kubernetes, a Kubernetes legend, and an awesome guy in general. :) For those who don’t know Jay, he is also one of the authors of the fantastic book Core Kubernetes (look it up!).

Harbor Registry – Automating LDAP/S Configuration – Part 2

This post continues our two-part series on automating LDAP configuration for Harbor Registry. In the previous post, we demonstrated how to achieve this using Ansible, running externally. However, external automation has its challenges, such as firewall restrictions or limited API access in some cases/environments.

Note: make sure you review the previous post as it provides a lot of additional background and clarifications on this process, LDAPS configuration, and more.

Here, we explore an alternative approach using Terraform, running the automation directly inside the Kubernetes cluster hosting Harbor. This method leverages native Kubernetes scheduling capabilities for running the configuration job in a fully declarative approach and does not require any network access to Harbor from the machine running the job.

Kubernetes Data Protection: Getting Started with Kasten (K10)

In a recent Kubernetes project I was involved in, our team had to conduct an in-depth proof of concept for several Kubernetes data protection solutions. The main highlights of the PoC covered data protection for stateful applications and databases, disaster recovery, and application mobility, including relocating applications across Kubernetes clusters and even different types of Kubernetes clusters (for example, from TKG on-premise to AWS EKS, etc.).

One of the solutions we evaluated was Kasten (K10), a data management platform for Kubernetes, which is now a part of Veeam. The implementation of Kasten was one of the smoothest we have ever experienced in terms of ease of use, stability, and general clarity around getting things done, as everything is very well documented, which certainly cannot be taken for granted these days. :)

Introduction

Since my previous posts on TAP Overview and Backstage, I have been diving deeper into TAP, trying to establish the practices around it.
