when install kubernetes dashboard using this command:
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yamlI check kubernetes service state like this:
kubectl get events --namespace=kube-systemIt give me this tip:
LAST SEEN TYPE REASON OBJECT MESSAGE
2m38s Warning ClusterIPOutOfRange service/kube-dns Cluster IP 10.43.0.10 is not within the service CIDR 10.254.0.0/16; please recreate service
2m38s Warning ClusterIPOutOfRange service/metrics-server Cluster IP 10.43.96.112 is not within the service CIDR 10.254.0.0/16; please recreate serviceis there any way to change my kube-dns service ip into CIDR range(I search from internet and no one change to ip by hand,should I tweak the kube-dns component config)?This is version info:
