I'm tired，what should I do?

Answer 1

Try rw tag while specifying the volume mounts. In your case that would be

docker run -d -p 3306:3306 -v "C:/ProgramFiles/MySQL/Config":/etc/mysql/:rw -v "C:/ProgramFiles/MySQL/Data/":/var/lib/mysql/:rw --name mysqlserver mysql/mysql-server

Answer 2

Looks like the file C:/Program Files/MySQL/Data/ on the host mounted as a volume in the container at /var/lib/mysql/ does not have write permission set.

You can give write permission (rw) when you mount /var/lib/mysql/ by doing

-v "C:/Program Files/MySQL/Data/":/var/lib/mysql/:rw

instead of

-v "C:/Program Files/MySQL/Data/":/var/lib/mysql/
