Support /etc/mysql/mariadb.conf.d/ and /etc/mysql/conf.d/

[williamdes]

You also could load them like /etc/my.cnf.d/ is loaded

From the upstream (mariadb) docker readme:

Custom configuration files should end in .cnf and be mounted at the directory /etc/mysql/conf.d. These files should contain the minimal changes from the MariaDB workload required for your application/environment. A MariaDB configuration file will have a [mariadb] group followed by variable = value settings per Setting Server System Variables or option-prefix-variable.

I can see that other linux distribution supports other folder names, but does it really make sense to go wider than upstream default? Does other containers do this?

[williamdes]

I think it should have as much support as the MariaDB container. I did not check that it supports it, but most probably it does

Mariadb seems to put its configs in /etc/mysql/mariadb.conf.d/ and you are expected to mount yours in /etc/mysql/conf.d/.

What are you looking for more specifically here? Layer your configs on top of defaults?

I expected both, but really I an not sure how they handle it
I just reported both directories because they are mysql or MariaDB images 😄

not really sure what you should really consider

If you were to mount into the folder they use while starting up, I'm thinking it would fail. They write configs there during startup.

As for conf.d - will definitely look at supporting that.

but you can mount only a file into it 😄
that's maybe why I did this in my configs, now that you explained that

You can mount a folder with many configs. I will implement this too!
