I worked at a government contractor and they were deploying a custom Java app on tomcat in windows. Entire team was into manual deployment and I was the DevOps engineer hired to automate. I worked for a year fighting all kinds of pushbacks and ultimately got it done. When I was leaving, the you who was going to run it, said “ansible is too complicated, we don’t need it after you leave.”

And that ladies and gentlemen, is the most useless project I’ve worked on. Hey atleast I got paid I guess.
