Important: MSR 2.9.x reaches End of Life (EOL) on 2026-DEC-01. Mirantis strongly recommends upgrading to the latest supported version to continue receiving updates, fixes, and support.

Software requirements

Prior to deploying MKE, consider the following software requirements:

  • Run the same version of MCR 19.03.8 or higher on all nodes.

  • Run Linux kernel 3.10 or higher on all nodes. For debugging purposes, the host OS kernel versions should match as closely as possible.

  • Use a static IP address for each node in the cluster.

Note

MKE does not support user namespaces for nodes.
