NAME¶

kubectl cluster-info dump - Dump relevant information for debugging and diagnosis

SYNOPSIS¶

kubectl cluster-info dump [OPTIONS]

DESCRIPTION¶

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.

OPTIONS¶

-A, --all-namespaces=false If true, dump all namespaces. If true, --namespaces is ignored.

--allow-missing-template-keys=true If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.

--namespaces=[] A comma separated list of namespaces to dump.

-o, --output="json" Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).

--output-directory="" Where to output the files. If empty or '-' uses stdout, otherwise creates a directory hierarchy in that directory

--pod-running-timeout=20s The length of time (like 5s, 2m, or 3h, higher than zero) to wait until at least one pod is running

--show-managed-fields=false If true, keep the managedFields when printing objects in JSON or YAML format.

--template="" Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].

OPTIONS INHERITED FROM PARENT COMMANDS¶

--as="" Username to impersonate for the operation. User could be a regular user or a service account in a namespace.

--as-group=[] Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

--as-uid="" UID to impersonate for the operation.

--azure-container-registry-config="" Path to the file containing Azure container registry configuration information.

--cache-dir="/home/username/.kube/cache" Default cache directory

--certificate-authority="" Path to a cert file for the certificate authority

--client-certificate="" Path to a client certificate file for TLS

--client-key="" Path to a client key file for TLS

--cluster="" The name of the kubeconfig cluster to use

--context="" The name of the kubeconfig context to use

--disable-compression=false If true, opt-out of response compression for all requests to the server

--insecure-skip-tls-verify=false If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure

--kubeconfig="" Path to the kubeconfig file to use for CLI requests.

--match-server-version=false Require server version to match client version

-n, --namespace="" If present, the namespace scope for this CLI request

--password="" Password for basic authentication to the API server

--profile="none" Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)

--profile-output="profile.pprof" Name of the file to write the profile to

--request-timeout="0" 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.

-s, --server="" The address and port of the Kubernetes API server

--tls-server-name="" Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used

--token="" Bearer token for authentication to the API server

--user="" The name of the kubeconfig user to use

--username="" Username for basic authentication to the API server

--version=false --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version

--warnings-as-errors=false Treat warnings received from the server as errors and exit with a non-zero exit code

  # Dump all namespaces to stdout


  kubectl cluster-info dump --all-namespaces


  


  # Dump a set of namespaces to /path/to/cluster-state
