Which mysql does docker install?

  docker, question

Many mysql images were found, so when installing, which one did you download?

And where are these images stored in the host? How to know the corresponding position?

Edit 1:
There are many things in the/var/lib/doc/aufs/diff directory. I don’t know what they are. there are only two images. why are there so many things in the directory?

Edit 2:
Mirrored in a virtual disk? However, the installed virtualbox cannot bring up the interface. How to find the location of the virtual disk?
