Mgt Development Environment - MySQL suddenly won't start - mysql

Question

I have 4 containers using mgt-commerce/mgt-development-environment-7.2. Basically everything runs well until I cannot access the control panel. It returns 500.
After checking the services, logs, etc, it seems like mysql is unable to start. Here is the error log captured in /var/log/mysql/error.log during starting mysql service using sudo service mysql start.

Is there anyone using this image ever getting this kind of error?
Update
It seems like mysql doesn't have the access to a particular file(s) or directory(ies), but I'm not sure which file(s) or directory(ies) . Here is the permission of mysql data directory:
clp#magento2dev:/$ ls -la /var/lib | grep mysql
drwxr-x--- 1 mysql mysql 4096 Sep 26 23:38 mysql
drwxrwx--- 2 mysql mysql 4096 Jul 11 15:24 mysql-files
