Fails to create root user if password policy plugin is used

[bjoernv]

The container creating fails, if a password policy plugin like simple_password_check is configured. This only happens, if the database directory is empty or the root does not exists.

This is the log:

[...]
---> 09:19:33     MySQL started successfully
This installation of MariaDB is already upgraded to 10.11.10-MariaDB.
There is no need to run mysql_upgrade again for 10.11.10-MariaDB.
You can use --force if you still want to run mysql_upgrade
---> 09:19:33     Setting password for MySQL root user ...
--------------
CREATE USER IF NOT EXISTS 'root'@'%'
--------------

ERROR 1819 (HY000) at line 1: Your password does not satisfy the current policy requirements (simple_password_check)

For testing you can use this my.cnf:

[mysqld]

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links = 0

# GlusterFS equivalent of 'lost+found'
ignore-db-dirs=.trashcan

# NetApp snapshot dir
ignore-db-dirs=.snapshot

!includedir /etc/my.cnf.d

plugin_dir = /usr/lib64/mariadb/plugin
plugin_load_add = simple_password_check
