Percona Kubernetes Operator for Percona Server for MongoDB


Percona Server for MongoDB (PSMDB) is an open-source enterprise MongoDB solution that helps you to ensure data availability for your applications while improving security and simplifying the development of new applications in the most demanding public, private, and hybrid cloud environments.

Based on our best practices for deployment and configuration, Percona Kubernetes Operator for PSMDB contains everything you need to quickly and consistently deploy and scale Percona Server for MongoDB instances into a Kubernetes cluster on-premises or in the cloud. It provides the following capabilities:

  • Easy deployment with no single point of failure
  • Sharding support
  • Scheduled and manual backups
  • Integrated monitoring with Percona Monitoring and Management
  • Smart Update to keep your database software up to date automatically
  • Automated Password Rotation – use the standard Kubernetes API to enforce password rotation policies for system user
  • Private container image registries


Percona Operators are based on the Operator SDK and leverage Kubernetes primitives to follow best CNCF practices.

Please read more about architecture and design decisions here.


It usually takes two steps to deploy Percona Server for MongoDB on Kubernetes:

  • Deploy the operator from deploy/bundle.yaml
  • Deploy the database cluster itself from deploy/cr.yaml
