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 %[1]d 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.

Syntax

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

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=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.
  -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 `=`, `==`, and `!=`.(e.g. -l              
            key1=value1,key2=value2). 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/template/#pkg-overview].
