cluster-info

Display addresses of the control plane and services with label kubernetes.io/cluster-service=true. To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump’.

Dump cluster information out suitable for debugging and diagnosing cluster problems. By default, dumps everything to stdout. You can optionally specify a directory with —output-directory. If you specify a directory, Kubernetes will build a set of files in that directory. By default, only dumps things in the current namespace and ‘kube-system’ namespace, but you can switch to a different namespace with the —namespaces flag, or specify —all-namespaces to dump all namespaces.

The command also dumps the logs of all of the pods in the cluster; these logs are dumped into different directories based on namespace and pod name.
