The document introduces the MySQL Operator for Kubernetes, which automates the deployment and management of MySQL databases on Kubernetes. It leverages MySQL InnoDB Cluster to deploy high availability MySQL clusters on Kubernetes with no data loss. The operator provides self-healing, backup/restore, and allows scaling MySQL servers and routers with minimal downtime. A public beta of the open source community edition will be released in the coming weeks.
