Enhancements

This section outlines new features implemented in the Cluster release 11.4.0 that is introduced in the Container Cloud release 2.20.0.

MKE and MCR version update

Updated the Mirantis Kubernetes Engine (MKE) version from 3.5.3 to 3.5.4 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, 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 11.4.0. 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.

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.

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.
