kubectl cluster-info dump
kubectl cluster-info dump
Dump lots of relevant info for debugging and diagnosis
Synopsis
Dumps cluster info 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 ‘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
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
Options

--match-server-version Require server version to match client version
-n, --namespace string If present, the namespace scope for this CLI request
--password string Password for basic authentication to the API server
--request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0")
