You seem to confuse containers with virtual machines. Those are very different concepts that solve different problems. You can't rely on containers alone if your goal is to ensure that your app will work on future operating systems. That's not something containers do. They only let you provide your own user space to run in a quasi-isolated environment, no more than that. You're still using the host's kernel which can still screw you up in multitude of ways (which is exactly what I said in my earlier comment), and you're still limited by API guarantees that the tools you use to make containers are providing you.
