The current approach is likely to run into several practical issues (e.g. file permission mismatches between host and container, the need to manually remove containers with `docker rm`, etc.) and addressing all of these reliably in Makefile can become quite messy. Writing a python (or even perl) script would make it much easier to maintain. Also, it can be self-documented quite nicely with `scripts/container.py --help` command.
