Yeah why not, i like my test faster :D
The mysql/mariadb container image contain an init script that will execute everything in /docker-entrypoint-initdb.d/
see Initializing a fresh instance
@ https://hub.docker.com/_/mariadb/
So let's run this initialization in a multi-stage build and copy the initialized DB in the new image :D
(see comments in dockerfile for details of the hack)
Clone this, then...
