I'm running a bootstrapped startup so a special case, my salary is nearly nothing :) :( :) At a bigger company you'd just ask a junior to set it up or maybe a sysadmin. You can probably contract to get part timers too. I guess I spent half a day or so setting up the CI cluster at the start and have barely touched it since. That wasn't much cost even if I was earning a big salary. Our builds can use caches to speed them up (not docker, other types of cache) and when we turned that on it was like a 3x speed win, so having persistent disks is definitely worth it for many types of program. Especially if you're brave and trust your build system to cache unit test results between builds!
