Ran into the same issue with the mysql docker container which ultimately bothered me into making my own. Started off experimenting with trapping signals (trap foo INT,..) similar to the article but found this nifty `--gdb` (nowadays `--debug-gdb`) flag to mysqld that enables more signal handling.

Source: `docker pull jbergstroem/mariadb-alpine`

edit: docker should really open the doors for a cleanup/shutdown phase. There's both entrypoint and cmd but not a "exit" command.
