Where are the mariadb, nginx, php dockerhub configs?

Question

Docker

I don’t understand what is happening with the official nginx, mariadb, php docker repositories. I want to share the path to the /etc/mysql or /etc/php configs, I don’t see anything in the end, I go into the container, it turns out to be empty, in php I generally found the configs in /usr/local/etc but when I start compose it writes there is no directory or a file, while indicating that it is fpm-conf that is missing, although how he saw it at all if the file is missing, somewhere I read that supposedly for the COPY instruction in the dockerfile this was done so that you could write the config from the host yourself, but there is at least something it should be, especially since in the description these directories are in dockerhub, and where you can find the configs separately

Answer 1

Is the problem still relevant? If yes, then give an example of the composer config in which you are trying to share the paths, without this it is difficult to understand what the problem is.
