MKE, MCR, and MSR Maintenance Lifecycle

MKE, MCR, and MSR Maintenance Lifecycle

The MKE/MCR/MSR subscription provides software, support, and certification to enterprise development and IT teams that build and manage critical apps in production at scale. It provides a trusted platform for all apps which supply integrated management and security across the app lifecycle, comprised primarily of Mirantis Kubernetes Engine (MKE), Mirantis Container Runtime (MCR), and Mirantis Secure Registry (MSR).

Mirantis validates the MKE/MCR/MSR platform for the operating system environments specified in the Compatibility Matrix, adhering to the Maintenance Lifecycle detailed here. Support for the MKE/MCR/MSR platform is defined in the Mirantis Cloud Native Platform Subscription Services agreement.

For the latest updates and upgrade instructions, refer to the release notes for MKE, MCR, and MSR.

Detailed here are all currently supported product versions, as well as the product versions most recently deprecated. It can be assumed that all earlier product versions are at End of Life (EOL).
