In this solution, the RKE cluster is deployed in a two-layer configuration using PowerFlex compute-only nodes that are deployed with the VMware ESXi hypervisor and dedicated provisioned disks on the PowerFlex backend storage. For more information about configuration of PowerFlex nodes, check the Configuration details. The management node hosts the vCenter appliance, PowerFlex Gateway

from the cloud to core and at the edge. Each distribution requires the bare minimum of host configuration, usually no more than a supported version of Docker. For edge deployments, SUSE Rancher does Kubernetes in the most efficient way possible. Kubernetes from SUSE Rancher with RKE uses a configuration syntax designed for clarity and dynamic cluster reconfiguration with no downtime. 3.1.1.2 application clusters happens through the installer GUI or via command-line directives that use a YAML configuration file. Clusters can run on vSphere, Amazon, Microsoft Azure or GCP nodes if operators choose to

Network configuration plane The network configuration plane interacts with Kubernetes control plane components to manage all CN2 resources the Contrail vRouter. Contrail controller This is the part of CN2 that provides the network configuration and network control plane functionality. This name is purely conceptual – there is no corresponding
