NAME

   kubectl label - Update the labels on a resource

SYNOPSIS

   kubectl label [OPTIONS]

DESCRIPTION

   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 63 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.

OPTIONS

   --all=false      Select all resources, in the namespace of the specified resource types

   -A, --all-namespaces=false      If true, check the specified action in all namespaces.

   --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.

   --dry-run="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="kubectl-label"      Name of the manager used to track field ownership.

   --field-selector=""      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=[]      Filename, directory, or URL to files identifying the resource to update the labels

   -k, --kustomize=""      Process the kustomization directory. This flag can't be used together with -f or -R.

   --list=false      If true, display the labels for a given resource.

   --local=false      If true, label will NOT contact api-server but run locally.

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

   --overwrite=false      If true, allow labels to be overwritten, otherwise reject label updates that overwrite existing labels.

   --record=false       Record  current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to
   updating the existing annotation value only if one already exists.

   -R, --recursive=false      Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.

   --resource-version=""      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, 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=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/tem
   plate/#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.

   --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

EXAMPLE

     # Update pod 'foo' with the label 'unhealthy' and the value 'true'
     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-
