StatefulSet consists of serviceName, replicas, template and volumeClaimTemplates:
* serviceName is “mysql”, headless service we created in previous section
* replicas is 3, the desired number of pod
* template is the configuration of pod
* volumeClaimTemplates is to claim volume for pod based on storageClassName,
mysql-gp2 that we created in the Define Storageclass section.
Percona Xtrabackup is used in the template to clone source MySQL server to its slaves.
