MKE, MSR, and MCR Maintenance Lifecycle¶
The MKE, MSR, and MCR platform 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, Mirantis Secure Registry (MSR), and Mirantis Container Runtime (MCR).
Mirantis validates the MKE, MSR, and MCR platform for the operating system environments specified in the mcr-23.0-compatibility-matrix, adhering to the Maintenance Lifecycle detailed here. Support for the MKE, MSR, and MCR platform is defined in the Mirantis Cloud Native Platform Subscription Services agreement.
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).
