I am running Percona Server 5.6 inside of docker container and it works until I am trying to mount internal /var/lib/mysql volume to the host directory /home/me/data to provide persistence between container restarts:
docker run -v /home/me/data:/var/lib/mysql percona-sql:tag
The error log is as following:

If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

I don’t really understand the problem here: “mysqld” is running in container with root privilege. Why doesn’t it have access rights to the “/var/lib/mysql” folder if it’s mounted to host directory
