kubectl cluster-info dump — Dump lots of relevant info for debugging and diagnosis.

Synopsis

kubectl cluster-info dump [Options]

Description

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.

Options

--all-namespaces=false
If true, dump all namespaces. If true, --namespaces is ignored.
--namespaces=[]
A comma separated list of namespaces to dump.
--output-directory=""
Where to output the files. If empty or '-' uses stdout, otherwise creates a directory hierarchy in that directory
