"Nuances" of using TeamCity

Hello everyone.

The article is written in the simple style of "DevOps for Housewives" from the same housewives. It will describe what surprises you may encounter when setting up a project in TeamCity. I will also give recommendations on how these problems can be circumvented.

The following is based on my two years of experience setting up TeamCity builds, reading bug reports and exchanging opinions with colleagues on the shop floor. I do not pretend to be the ultimate truth, since the SDD (Stackoverflow Driven Development) approach was mainly used in the work.
