There is no difference to building the different versions. It does not matter if you are compiling in a Docker container or virtualized in any way as that would be exactly like a normal environment. As long as you have the build prerequisities installed it should be as simple as "make menuconfig && make V=99". I can't understand that you tried 10+ times and did not manage to build Did you create a thread in the forum with your error? The error message should tell you exactly what went wrong, so with the internet at your disposal it should be easy to fix.
You don't actually need to compile your own either. You can just go with the stable releases or a snapshot if you like.
