StackLight

* - 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.

*** - 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.

OpenStack Yoga is supported since Container Cloud 2.21.1.

**** - Only Cinder API V3 is supported.

***** - 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.

RHEL 8.4 and CentOS 7.9 deployments of vSphere-based clusters are available as Technology Preview features.

****** - Packer builds a vSphere virtual machine (VM) template that is based on Ubuntu 20.04 with kernel 5.4.0-125-generic. If you build a VM template manually, we recommend installing the same kernel version 5.4.0-125-generic.
