I always find Jenkins to be an absolute nightmare. The IT/“devops” people hand install it (most likely on your incredibly unreliable on-prem VSphere or whatever) and then immediately forget about it. Of course, mere developers aren’t not capable of such a feat of system administration as installing Jenkins. Then three months later when it starts failing due to disk space or memory issues you have to beg them to fix it so you can keep working.
