This section outlines new features and enhancements introduced in the Mirantis Container Cloud release 2.2.0. For the list of enhancements in the Cluster release 5.9.0 and Cluster release 6.8.1 introduced by the Container Cloud release 2.2.0, see 5.9.0 and 6.8.1.

Support for VMware vSphere provider on RHEL


Introduced the Technology Preview support for the VMware vSphere cloud provider on RHEL, including support for creation and operating of managed clusters using the Container Cloud web UI.

Deployment of an additional regional vSphere-based cluster or attaching an existing Mirantis Kubernetes Engine (MKE) cluster to a vSphere-based management cluster is on the development stage and will be announced in one of the following Container Cloud releases.


For the Technology Preview feature definition, refer to Technology Preview features.

Kernel parameters management through BareMetalHostProfile

Implemented the API for managing kernel parameters typically managed by sysctl for bare metal hosts through the BareMetalHost and BareMetalHostProfile objects fields.

Support of multiple subnets per cluster

Implemented support of multiple subnets per a Container Cloud cluster with an ability to specify a different network type for each subnet. Introduced the SubnetPool object that allows for automatic creation of the Subnet objects. Also, added the L3Layout section to L2Template.spec. The L3Layout configuration allows defining the subnets scopes to be used and to enable auto-creation of subnets from a subnet pool.

Optimization of the Container Cloud logs collection

Optimized user experience with the Container Cloud resources logs collection:

  • Added a separate file with a human-readable table that contains information about cluster events

  • Implemented collecting of system logs from cluster nodes

Container Cloud API documentation for bare metal

On top of continuous improvements delivered to the existing Container Cloud guides, added the Mirantis Container Cloud API section to the Operations Guide. This section is intended only for advanced Infrastructure Operators who are familiar with Kubernetes Cluster API.

Currently, this section contains descriptions and examples of the Container Cloud API resources for the bare metal cloud provider. The API documentation for the OpenStack, AWS, and VMware vSphere API resources will be added in the upcoming Container Cloud releases.
