What Hacker News says?
I'm always a bit confused about the CPU limit (for the pod), some guides (and tools) advice to always set one, but this one [0] doesn't. Ops people I worked with almost always want to lower that limit and I have to insist for raising it (no way they disable it). Is there an ultimate best practice for that?

HN discussionWow! Based on the title I was prepared to lump this in with the "kill pods via doom" category but this is so much more and honestly inspiring to build on more fun ideas. Congrats on shipping and the content quality of the intro at https://learnk8s.io/real-time-dashboard is fantastic.

HN discussionYou should write an operator for inner checks. This might be helpful: https://learnk8s.io/troubleshooting-deployments I am planning to do the same for a platform that I am building, and is deployed on prem. Let me know if this is an open source project.
