It's not that you can't, you just have to be mindful. Because docker containers contain compiled applications, you have to be aware of what CPU architecture they're compiled for. ARM can't natively run x86 binaries, x86 can't natively run ARM binaries. If you want to develop containers for x86 systems on an ARM system, you'll have to cross compile your containers, which I'm not sure if docker actually supports outside of emulation. If you are only a consumer of containers, most of the popular ones have been compiled for multiple architectures.
