kubectl label — Update the labels on a resource


kubectl label [Options]


Update the labels on a resource.

A label must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters. If --overwrite is true, then existing labels can be overwritten, otherwise attempting to overwrite a label will result in an error. If --resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used.


select all resources in the namespace of the specified resource types
If true, only print the object that would be sent, without sending it.
-f, --filename=[]
Filename, directory, or URL to a file identifying the resource to update the labels
If true, include definitions of new APIs via calls to the API server. [default true]
When using the default output, don't print headers.
-o, --output=""
Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [ ⟨http://golang.org/pkg/text/template/#pk…⟩] and jsonpath template [ ⟨http://releases.k8s.io/release-1.3/docs…⟩].
Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
If true, allow labels to be overwritten, otherwise reject label updates that overwrite existing labels.
Record current kubectl command in the resource annotation.
-R, --recursive=false
Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
If non-empty, the labels update will only succeed if this is the current resource-version for the object. Only valid when specifying a single resource.
-l, --selector=""
Selector (label query) to filter on
-a, --show-all=false
When printing, show all resources (default hide terminated pods.)
When printing, show all labels as the last column (default hide labels column)
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 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/#pk…⟩].
