kubectl annotate

    Synopsis

    Update the annotations on one or more resources.

    All Kubernetes objects support the ability to store additional data with the object as annotations. Annotations are key/value pairs that can be larger than labels and include arbitrary string values such as structured JSON. Tools and system extensions may use annotations to store their own data.

    Attempting to set an annotation that already exists will fail unless --overwrite is set. If --resource-version is specified and does not match the current resource version on the server the command will fail.

    Use "kubectl api-resources" for a complete list of supported resources.

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

    Examples

      # Update pod 'foo' with the annotation 'description' and the value 'my frontend'
  # If the same annotation is set multiple times, only the last value will be applied
  kubectl annotate pods foo description='my frontend'
  
  # Update a pod identified by type and name in "pod.json"
  kubectl annotate -f pod.json description='my frontend'
  
  # Update pod 'foo' with the annotation 'description' and the value 'my frontend running nginx', overwriting any existing value
  kubectl annotate --overwrite pods foo description='my frontend running nginx'
  
  # Update all pods in the namespace
  kubectl annotate pods --all description='my frontend running nginx'
  
  # Update pod 'foo' only if the resource is unchanged from version 1
  kubectl annotate pods foo description='my frontend running nginx' --resource-version=1
  
  # Update pod 'foo' by removing an annotation named 'description' if it exists
  # Does not require the --overwrite flag
  kubectl annotate pods foo description-

    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-annotate"

    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 annotation

    -h, --help

    help for annotate

    -k, --kustomize string

    Process the kustomization directory. This flag can't be used together with -f or -R.

    --list

    If true, display the annotations for a given resource.

    --local

    If true, annotation 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 annotations to be overwritten, otherwise reject annotation updates that overwrite existing annotations.

    -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 annotation 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].

    --as string

    Username to impersonate for the operation. User could be a regular user or a service account in a namespace.

    --as-group strings

    Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

    --as-uid string

    UID to impersonate for the operation.

    --default-unreachable-toleration-seconds int     Default: 300

    Indicates the tolerationSeconds of the toleration for unreachable:NoExecute that is added by default to every pod that does not already have such a toleration.

    --disable-compression

    If true, opt-out of response compression for all requests to the server

    --insecure-skip-tls-verify

    If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
