I’m confused about something. I’m new to using volumes and trying to understand something about an application that needs persistent file storage, like WordPress. I’m using this image: https://hub.docker.com/_/wordpress. The docker-compose.yml file uses a volume to store the MySQL data:
Which I think I understand how that part works, but what I don’t understand is where are the changes files stored? For example, if I install a WordPress plugin, yes, the MySQL data storage is persistent, but about the plugin files that are added to the file system? What am I missing here?
