Mariadb Galera Cluster Kubernetes

Galera is a database clustering solution that enables you to set up multimaster clusters using synchronous replication Galera automatically handles keeping the data on different nodes in sync while allowing you to send read and write queries to any of the nodes in the cluster You can learn more about Galera at the official documentation page.

Once the GKE cluster is up and running, and Portworx is installed and configured, we will deploy a highly available MariaDB database Through Kubernetes storage class objects, an admin can define different classes of Portworx volumes that are offered in a cluster These classes will be used during the dynamic provisioning of volumes. A multimaster cluster is one where each database instance is a master of course The cluster contains no readreplicas, slave nodes, or 2nd class instances.
