Permission Issues with latest version of docker

Not sure if anyone else is seeing this - but I am seeing major permission issues with mysql and latest docker (18.09.1 - ubuntu 18.04 host) wasn’t able to fix it with my usual tricks. Looks like mysql not able to write to /var/lib/mysql/mysql even though perms are not correct.

Anyway - just a word of warning - I am currently rebuilding my server. The problem didn’t occur until I upgraded seafile to latest too - then some combo of the 2 broke everything. Pretty sure it’s a docker thing though - not seafile as I’ve downgraded and still the same.
