The commands/steps listed on this page can be used to check clusters that you are importing or that are imported in Rancher.
Make sure you configured the correct kubeconfig (for example,
Communication to the cluster (Kubernetes API via cattle-cluster-agent) and communication to the nodes is done through Rancher agents.
If the cattle-cluster-agent cannot connect to the configured
server-url, the cluster will remain in Pending state, showing
Waiting for full cluster configuration.
Check if the cattle-node-agent pods are present on each node, have status Running and don’t have a high count of Restarts:
kubectl -n cattle-system get pods -l app=cattle-agent -o wide
NAME READY STATUS RESTARTS AGE IP NODE cattle-node-agent-4gc2p 1/1 Running 0 2h x.x.x.x worker-1 cattle-node-agent-8cxkk 1/1 Running 0 2h x.x.x.x etcd-1 cattle-node-agent-kzrlg 1/1 Running 0 2h x.x.x.x etcd-0 cattle-node-agent-nclz9 1/1 Running 0 2h x.x.x.x controlplane-0 cattle-node-agent-pwxp7 1/1 Running 0 2h x.x.x.x worker-0 cattle-node-agent-t5484 1/1 Running 0 2h x.x.x.x controlplane-1 cattle-node-agent-t8mtz 1/1 Running 0 2h x.x.x.x etcd-2
Check logging of a specific cattle-node-agent pod or all cattle-node-agent pods:
kubectl -n cattle-system logs -l app=cattle-agent
Check if the cattle-cluster-agent pod is present in the cluster, has status Running and doesn’t have a high count of Restarts:
kubectl -n cattle-system get pods -l app=cattle-cluster-agent -o wide
NAME READY STATUS RESTARTS AGE IP NODE cattle-cluster-agent-54d7c6c54d-ht9h4 1/1 Running 0 2h x.x.x.x worker-1
Check logging of cattle-cluster-agent pod:
kubectl -n cattle-system logs -l app=cattle-cluster-agent
