.SH SYNOPSIS

\fBkubectl cluster\-info dump\fP [OPTIONS]

.SH DESCRIPTION
|
|
.PP
|
|
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.
|
|
|
|
.PP
|
|
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.
