* - The Cluster release version is deprecated and will become unsupported in one of the following Container Cloud releases.
** - Attachment of non Container Cloud based MKE clusters is supported on Ubuntu 20.04, RHEL 7.9, and CentOS 7.9.
*** - RHEL 7.8 deployment is possible with allowed access to the
rhel-7-server-rpms repository provided by the Red Hat Enterprise Linux
Server 7 x86_64.
Verify that your RHEL license or activation key meets this requirement.
**** Ubuntu 20.04 is installed by default on greenfield deployments:
Since 2.18.1, for MOSK clusters
Since 2.18.0, for the vSphere provider
Since 2.17.0, for all supported providers except vSphere and MOSK clusters
Since 2.16.0, only for the bare metal provider on non-MOSK-based managed clusters as Technology Preview
***** - Only Cinder API V3 is supported.
****** - On the MOSK Victoria with Tungsten Fabric clusters of Container Cloud deployed before MOSK 22.3, Octavia enables a default security group for newly created load balancers. To change this configuration, refer to MOSK Operations Guide: Configure load balancing. To use the default security group, configure ingress rules as described in Bootstrap a management cluster or Create a managed cluster.
