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

Mirantis has transitioned to an OCI-based Helm registry for registry.mirantis.com. As a result, Helm repository management is no longer required. Commands that rely on Helm repository operations, such as helm repo update and helm upgrade, will fail with HTTP 4xx errors.

For both new installations and upgrades, use the OCI-based registry URL directly. To check for available upgrades, run helm upgrade --dry-run without specifying a version.

For more details, see the Helm documentation.
