if the namespace was overridden
We use a pod monitor as below, and password by env override with for example
CREATE USER 'exporter'@'127.0.0.1' IDENTIFIED BY 'exporter' WITH MAX_USER_CONNECTIONS 3;
GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'exporter'@'127.0.0.1';
An alternative would be to use socket+root, but the exporter runs
as nonroot properly and I'd recommend against making it root.

Also let's remove obsolete variants. Note that scale-2 is not recommended as Galera cluster size.
when using an overlay with "namespace:"
I still think it's the default behavior, but maybe the entrypoint script hasn't been updated to reflect the invalid-by-default root pwd. Without these envs you get: [ERROR] [Entrypoint]: Database is uninitialized and password option is not specified You need to specify one of MARIADB_ROOT_PASSWORD, MARIADB_ALLOW_EMPTY_ROOT_PASSWORD and MARIADB_RANDOM_ROOT_PASSWORD This reverts commit ac5ffea.
and as the comment suggested it actually caused downtime for a large state transfer
