Name Shorthand Default Usage
all-namespaces false If present, list the requested object(s) across all namespaces. Namespace in current context is ignored even if specified with --namespace.
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.
experimental-use-openapi-print-columns false If true, use x-kubernetes-print-column metadata (if present) from openapi schema for displaying a resource.
export false If true, use 'export' for the resources. Exported resources are stripped of cluster-specific information.
filename f [] Filename, directory, or URL to files identifying the resource to get from a server.
ignore-not-found false Treat "resource not found" as a successful retrieval.
include-extended-apis true If true, include definitions of new APIs via calls to the API server. [default true]
label-columns L [] Accepts a comma separated list of labels that are going to be presented as columns. Names are case-sensitive. You can also use multiple flag options like -L label1 -L label2...
no-headers false When using the default or custom-column output format, don't print headers (default print headers).
output o Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
output-version DEPRECATED: To use a specific API version, fully-qualify the resource, version, and group (for example: 'jobs.v1.batch/myjob').
raw Raw URI to request from the server. Uses the transport specified by the kubeconfig file.
recursive R false Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
schema-cache-dir ~/.kube/schema If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema'
selector l Selector (label query) to filter on, supports '=', '==', and '!='.
show-all a false When printing, show all resources (default hide terminated pods.)
show-kind false If present, list the resource type for the requested object(s).
show-labels false When printing, show all labels as the last column (default hide labels column)
sort-by If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
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].
watch w false After listing/getting the requested object, watch for changes.
watch-only false Watch for changes to the requested object(s), without listing/getting first.
