    Description

      The docker official images of MariaDB create a .my-healthcheck.cnf file in the datadir so k8s/container services can perform a healthcheck against the current running instances.

      Since the mariadb operator now supports galera, it would be good if it works correctly during sst scripts,. The liveness/readiness probes are a waiting feature, but simple enough to implement.

      As the test https://github.com/MariaDB/mariadb.org-tools/tree/master/daniel/galera-sst-test shows it starts failing healthcheck tests after being a SST joiner.
