Usage

Overview

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, kyaml, 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.

--as-user-extra=[]
User extras to impersonate for the operation, this flag can be repeated to specify multiple values for the same key.

--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.

--kuberc=""
Path to the kuberc file to use for preferences. This can be disabled by exporting KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.

--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|trace)

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

--proxy-url=""
Proxy URL to use for requests to the API server

--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
