I hope this comes off as a constructive criticism. I noticed the extensive use of the word DevOps throughout this article. I know its about tools that could help facilitate DevOps culture, however the continuous push for the word "DevOps tools" in each heading seems a bit redundant and a little hard to take seriously. The article overall gives me more AI vibes than a human written one. Perhaps you could try to blend in some tidbits here and there or change up some structure to make the blog more human like. Maybe even include some analogies to the tools you are mentioning and how you understood the tool better or something.

part 2 when ? also nice kubectl hack. didn't know that.

good read, but you said "I learn two key things" and listed five key things.
