Hello, this is Mosuke. This article is part of the OpenShift Advent Calendar 2025.

I learned that MCP (Model Context Protocol) can be installed on OpenShift Lightspeed (although it is still in Developer Preview), so I decided to try it out immediately.

MCP is also introduced in the following Red Hat article.

This time, just following the article wouldn’t be very interesting, so I’d like to try installing a different MCP server. I will be using kubernetes-mcp-server.

Hello, this is mosuke.
I finally took the CKS(Certified Kubernetes Security) and passed. This entry describes the study methods and the testing environment.

Hello, this is mosuke.
Today, I would like to confirm the behavior of pods when a node failure occurs in Kubernetes. Until now, I had an incorrect understanding of pod behavior and scheduling in the event of node failure. I am ashamed to admit it, but I would like to explain what I have confirmed for those who have the same misconceptions.
