Chai published on 2020-11-06 included in Tech Articles

I have used a few hosting websites like Hpage, wordpress.com, etc.. for a long time. But I wanted to host my website on something free and fast. I thought of using GitHub pages, but converting my WordPress site to Github pages was a very big task for me. I was looking for easy to use software to generate MD pages. That’s where I’ve found Hugo. Hugo is a very lightweight software to generate a static website of your own.

Auto Deploy new VDI in xendesktop catalog

Chai published on 2018-04-03 included in Citrix Tools and Scripts XenApp and XenDesktop 7.X IMP Posts Scripts and Automation

As part of day to day tasks, one of the major activity for citrix admins is to maintain free VDIs in xendesktop delivery groups. If we dont have registered free VDI machines, and when new users try to connect to VDI, they would get errors like “Cannot start VM”. So, we have to make sure we have enough free VDIs in delivery groups. As a part of this process, I wrote a powershell script that would auto provision new VDIs to a given catalog and add them to delivery group.

Kubernetes Services - Load Balancer

Chai published on 2026-04-09 included in Kubernetes

The NodePort Limitation Consider a four-node cluster hosting front-end applications, such as a voting app and a result app. To expose these via NodePort, Kubernetes allocates a port from the default range (30000-32767) on every node. Even if the application pods reside on only two nodes (e.g., nodes with IPs 70 and 71), the NodePort service creates iptables rules across all nodes. Consequently, a user can access the application via any node IP in the cluster.
