Server node In Rancher terminology, a server node is a Kubernetes control plane node. 4 Table 1: Terminology (Continued) Description Configuration Plane1 contrail-k8s-apiserver Control Plane Node This pod is an aggregated API server that is the entry point for managing all Contrail resources. It is registered with the regular kube-apiserver

cluster. Kubernetes monitors the clusters at multiple levels. Heapster is used to aggregate vital metrics, while the kubelet node agent queries cAdvisor to fetch data from containers and provide to Heapster a Rancher server is easy. You can set one up by following instructions here, or if you wish to use Vagrant, you can clone the repo here and run vagrant up. When you deploy Rancher server, you should Once you run above command on a new machine, the host(s) tries to contact the Rancher server with the key. The server then verifies the key and registers the agent. Based on the environment to which the

to resources at the Global, Cluster, and Namespace levels. Users with access to the SUSE Rancher server will only see their own clusters or projects, and the optional namespace isolation assures that require that a cluster administrator perform the upgrade. However, the dependency on the management server and the number of steps needed implies that upgrades are not user friendly. Clusters deployed through airgap installations and includes comprehensive documentation on how to provision a private registry server and populate it with all images needed for the installation. 3.1.15.2 OpenShift OpenShift
