Question Location of my.cnf with Docker

[cool_sh]

Hi,

i am wondering where exactly the configruation file vor MySQL can be found when using mysql in a docker container.

But neither inside the folders used with "Volume-Mapping" nor below /var/lib/docker/devicemapper/mnt/<id>/* I am able to find the right one.

I think a lot of you use this solution for additional versions of mysql, who can help?

If you're using the MySQL Docker container, you should be passing my.cnf values when creating the container anyways, not after creating it - docker containers are empheral.

If it's some other container that has MySQL bundled, it'll depend, but usually its either /etc/my.cnf, or in /etc/my.cnf.d

Thanks,
yes its directly mysql from docker hub.

Sorry for the stupid question but how can i pass additional parameters? Didn't get the syntax to be used e.g.
-e"set @innodb_buffer_pool_instances=2;" - where to put this in?

You do it as environment variables, which you set in Plesk, or pass when running docker run
