Warning: In correlation with the end of life (EOL) date for MSR 3.1.x, Mirantis stopped maintaining this documentation version as of 2025-09-27. The latest MSR product documentation is available here.

Important

The Postgres Operator version you install must be 1.10.0 or later, as all versions up through 1.8.2 use the PodDisruptionBudget policy/v1beta1 Kubernetes API, which is no longer served as of Kubernetes 1.25. This being the case, various MSR features may not function properly if a Postgres Operator prior to 1.10.0 is installed alongside MSR on Kubernetes 1.25 or later.
