kubectl cluster-info dump
Synopsis
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.
kubectl cluster-info dump [flags]
Examples
# Dump current cluster state to stdout
kubectl cluster-info dump
# Dump current cluster state to /path/to/cluster-state
kubectl cluster-info dump --output-directory=/path/to/cluster-state
# Dump all namespaces to stdout
kubectl cluster-info dump --all-namespaces
# Dump a set of namespaces to /path/to/cluster-state
kubectl cluster-info dump --namespaces default,kube-system --output-directory=/path/to/cluster-state
