Description:
Please enable mysqld command line arguments. It would be really nice to be able to change the default port without having to edit the my.cnf file. https://dev.mysql.com/doc/refman/5.7/en/server-options.html

How to repeat:
build and run mysql/mysql-server:5.7

Suggested fix:
Modify the entrypoint.sh file to look for an env variable that contains comma separated command line key value pairs (MYSQLD_OPTS=-P=4222,--port-open-timeout=1000)

Hi,

The docker image already supports passing on arguments to the server by simply adding them to the command;

With docker run:
«docker run [...] mysql/mysql-server:5.7 mysqld --port=3307» (note that "mysqld" is optional

Compose:
«command: mysqld --port=3307»
