Enhancements¶
This section outlines new features implemented in the Cluster release 7.10.0 that is introduced in the Container Cloud release 2.20.0.
MKE and MCR version update¶
Updated the Mirantis Kubernetes Engine (MKE) version from 3.4.9 to 3.4.10 and the Mirantis Container Runtime (MCR) version from 20.10.11 to 20.10.12 for the Container Cloud management, regional, and managed clusters on all supported cloud providers except MOSK-based deployments, as well as for non Container Cloud based MKE cluster attachment.
Ceph removal from management and regional clusters¶
To reduce resource consumption, removed Ceph cluster deployment from management and regional clusters based on bare metal and Equinix Metal with private networking. Ceph is automatically removed during the Cluster release update to 7.10.0. Managed clusters continue using Ceph as a distributed storage system.
Creation of Ceph RADOS Gateway users¶
Implemented the objectUsers RADOS Gateway parameter in the
KaaSCephCluster CR. The new parameter allows for an easy creation of custom
Ceph RADOS Gateway users with permission rules. The users parameter is now
deprecated and, if specified, will be automatically transformed to
objectUsers.
Caution
For MKE clusters that are part of MOSK infrastructure, the feature support will become available in one of the following Container Cloud releases.

Custom RBD map options¶
Implemented the rbdDeviceMapOptions field in the Ceph pool parameters of
the KaaSCephCluster CR. The new field allows specifying custom RADOS Block
Device (RBD) map options to use with StorageClass of a corresponding Ceph
pool.
Caution
For MKE clusters that are part of MOSK infrastructure, the feature support will become available in one of the following Container Cloud releases.

Ceph Manager modules configuration¶
Implemented the mgr.mgrModules parameter that includes the name and
enabled keys to provide the capability to disable a particular Ceph Manager
module. The mgr.modules parameter is now deprecated and, if specified, will
be automatically transformed to mgr.mgrModules.
Ceph daemons health check configuration¶
Implemented the capability to configure health checks and liveness probe
settings for Ceph daemons through the KaaSCephCluster CR.
Caution
For MKE clusters that are part of MOSK infrastructure, the feature support will become available in one of the following Container Cloud releases.
