The Mirantis Container Cloud release compatibility matrix outlines the specific operating environments that are validated and supported.
The document provides the deployment compatibility for each product release and determines the upgrade paths between major components versions when upgrading.
A Container Cloud management cluster upgrades automatically when a new product release becomes available. Once the management cluster has been updated, the user may trigger the managed clusters upgrade through the Container Cloud web UI or API.
To view the full components list with their respective versions for each Container Cloud release, refer to the Container Cloud Release Notes related to the release version of your deployment or use the Releases section in the web UI or API.
Caution
The document applies to the Container Cloud regular deployments. For supported configurations of existing Mirantis Kubernetes Engine (MKE) clusters that are not deployed by Container Cloud, refer to MKE, MSR, and MCR Compatibility Matrix.
The following table outlines the compatibility matrix of the most recent Container Cloud and Cluster releases with their components versions. For details about unsupported releases, see Container Cloud releases history.
