System Requirements

The Operator was developed and tested with Percona Server for MongoDB 5.0.26-22, 6.0.15-12, and 7.0.8-5. Other options may also work but have not been tested. The Operator 1.16.1 also uses Percona Backup for MongoDB 2.4.1.

Officially supported platforms

The following platforms were tested and are officially supported by the Operator 1.16.1:

Other Kubernetes platforms may also work but have not been tested.

Resource Limits

A cluster running an officially supported platform contains at least 3 Nodes and the following resources (if sharding is turned off):

  • 2GB of RAM,
  • 2 CPU threads per Node for Pods provisioning,
  • at least 60GB of available storage for Private Volumes provisioning.

Consider using 4 CPU and 6 GB of RAM if sharding is turned on (the default behavior).

Also, the number of Replica Set Nodes should not be odd if Arbiter is not enabled.


Use Storage Class with XFS as the default filesystem if possible to achieve better MongoDB performance .
