Out of the box, metrics-server doesn’t work on a kubeadm managed k8s server. When deployed out of the box, the associated pod goes into a CrashLoopBackOff state. In order to fix this issue, we have to edit the deployment and add a few parameters — Following relevant section of the deployment file is shown in a “before/after” state below — …Installing metrics-server on a kubeadm managed k8s cluster Read More »
- Platform Automation and Infrastructure as Code – 2
In the first post of this series, I had alluded to walking through terraform and how it can be leveraged as a standard tool for deployment across a variety of environments. In this post, I will walk through the basics pre-requisites I understand them, to start using terraform on both AWS as well as Azure. How to run Terraform The …Platform Automation and Infrastructure as Code – 2 Read More »

- Kicking the Tires on Kubernetes — Part 5The topic of providing a persistent storage in the Kubernetes world is simpler today than it was a couple of years back. In order for this series and my personal edification, I opted to set up GlusterFS on the Kubernetes nodes in what is known as a “hyper-converged” deployment. The industry terms of “converged” and “hyper-converged” infrastructure denote the manner …
