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.

  1. kubectl cluster-info dump [flags]

  2.   kubectl cluster-info dump
  4.   # Dump current cluster state to /path/to/cluster-state
  5.   kubectl cluster-info dump --output-directory=/path/to/cluster-state
  7.   # Dump all namespaces to stdout
  8.   kubectl cluster-info dump --all-namespaces
  10.   # Dump a set of namespaces to /path/to/cluster-state
  11.   kubectl cluster-info dump --namespaces default,kube-system --output-directory=/path/to/cluster-state
