This also depends on what kind of software or if it's a hobby vs work related.

I usually do the opposite, even if there's a docker image available, to try it out I follow the build and manual setup. I need to know _how_ it works even if at the end I use the image. If something breaks, I own this and need to be able to debug it. Depending on the program and its architecture, I also need to know how to scale it.
