* - 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.
