NAME¶

kubectl annotate - Update the annotations on a resource

SYNOPSIS¶

kubectl annotate [OPTIONS]

DESCRIPTION¶

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.

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-annotate" 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 annotation

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

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

--local=false If true, annotation 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 annotations to be overwritten, otherwise reject annotation updates that overwrite existing annotations.

--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 annotation 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].

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.

--azure-container-registry-config="" Path to the file containing Azure container registry configuration information.

--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 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-
