Enhancements¶

Updated versions of Mirantis Kubernetes Engine and Container Runtime¶

Updated the Mirantis Kubernetes Engine (MKE) version to 3.3.4 and the Mirantis Container Runtime (MCR) version to 19.03.13 for the Container Cloud management and managed clusters.

For the MKE release highlights and components versions, see MKE, MSR, and MCR documentation: Mirantis Kubernetes Engine release notes.

For the Mirantis Container Runtime release highlights, see MKE, MSR, and MCR documentation: Mirantis Container Runtime release notes.

Additional regional cluster on VMware vSphere¶

^{Technical Preview}

In scope of Technology Preview support for the VMware vSphere provider, added the capability to deploy an additional regional vSphere-based cluster on top of the vSphere management cluster to create managed clusters with different configurations if required.

Automated setup of an OVF template for the VMware vSphere provider¶

^{Technical Preview}

Automated the process of an OVF template setup for the vSphere-based management and managed clusters deployments. The OVF template is now set up by Packer using the vsphere_template flag that is integrated into bootstrap.sh.

StackLight support for VMware vSphere¶

^{Technical Preview}

Added the capability to deploy StackLight on management clusters. However, such deployment has the following limitations:

• The Kubernetes Nodes and Kubernetes Cluster Grafana dashboards may have empty panels.

• The DockerNetworkUnhealthy and etcdGRPCRequestsSlow alerts may fail to raise.

• The CPUThrottlingHigh, CalicoDatapaneIfaceMsgBatchSizeHigh, KubeCPUOvercommitPods, KubeMemOvercommitPods alerts, and the TargetDown alert for the prometheus-node-exporter and calico-node pods may be constantly firing.

Support of multiple host-specific L2 templates per a bare metal cluster¶

Added support of multiple host-specific L2 templates to be applied to different nodes of the same bare metal cluster. Now, you can use several independent host-specific L2 templates on a cluster to support different hardware configurations. For example, you can create L2 templates with a different number and layout of NICs to be applied to the specific machines of a cluster.

Improvements in the Container Cloud logs collection¶

Improved user experience with the Container Cloud resources logs collection by implementing collecting of logs on the Mirantis Kubernetes Engine cluster and on all Kubernetes pods, including the ones that were previously removed or failed.
