kubectl label

    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 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.
    kubectl label [--overwrite] (-f FILENAME | TYPE NAME) KEY_1=VAL_1 ... KEY_N=VAL_N [--resource-version=version]

    Examples

      # 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-

    Options

    --all

    Select all resources, in the namespace of the specified resource types

    -A, --all-namespaces

    If true, check the specified action in all namespaces.

    --allow-missing-template-keys     Default: 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 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 true, 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 '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). 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].
