For me the big advantage of doing more in docker and lees in the CIT environment is that I have less lock-in/dependency to whatever my CI provider does. I try to reduce my CI scripts to something like

    docker build
    docker run image test 

All complexities of building and collecting dependencies go in dockerfiles, so I can reproduce it locally, or anywhere else. And importantly, without messing with any system settings/packages. No more makefiles or shell scripts that make a ton of assumptions about your laptop that need to be set just right to build something from source; just docker build and off you go. Such a hassle when you need to follow pages of readme just to build something from source (plus a lot of installed dependencies that you have to clean up afterwards)
