## 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
|
|
|
|
```
|
|
--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
