Rancher RKE2 Cluster | 59 Configure a Server Node | 59 Configure an Agent Node | 63 Configure Repository Credentials | 66 Prepare a Cluster Node for DPDK | 67 Juniper CN2 Technology Previews controllers manage a distributed set of data planes implemented by a CNI plug-in and vRouter on every node. Integrating a full-fledged vRouter alongside the workloads provides CN2 the flexibility to support such as link and node failures. The Contrail controller reports and logs these events where appropriate and reconfigures the vRouter data plane as necessary. Although any single node can contain only

all machines are managed as a cluster (or set of clusters, depending on the topology used). Node A logical machine unit (physical or virtual), which is part of a larger cluster on which you can vast cluster running a large number of nodes. When a container fails on a given node, it may be launched on a different node. How do you ensure that all other containers connecting to that failed container 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. The performance data
