kubectl annotate — Update the annotations on a resource

Synopsis

kubectl annotate [Options]

Description

Update the annotations on one or more resources.

An annotation is a key/value pair that can hold larger (compared to a label), and possibly not human-readable, data. It is intended to store non-identifying auxiliary data, especially data manipulated by tools and system extensions. If --overwrite is true, then existing annotations can be overwritten, otherwise attempting to overwrite an annotation 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.

Possible resources include (case insensitive):
pod (po), service (svc), replicationcontroller (rc),
node (no), event (ev), componentstatuse (cs),
limitrange (limits), persistentvolume (pv), persistentvolumeclaim (pvc),
horizontalpodautoscaler (hpa), resourcequota (quota), secret

Options

--all=false
select all resources in the namespace of the specified resource types
-f, --filename=[]
Filename, directory, or URL to a file identifying the resource to update the annotation
--include-extended-apis=true
If true, include definitions of new APIs via calls to the API server. [default true]
--no-headers=false
When using the default output, don't print headers.
-o, --output=""
Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [ ⟨http://golang.org/pkg/text/template/#pk…⟩] and jsonpath template [ ⟨http://releases.k8s.io/release-1.3/docs…⟩].
--output-version=""
Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
--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.
-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
-a, --show-all=false
When printing, show all resources (default hide terminated pods.)
--show-labels=false
When printing, show all labels as the last column (default hide labels column)
--sort-by=""
If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
--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/#pk…⟩].

--username=""
Username for basic authentication to the API server.

--v=0
log level for V logs

--vmodule=
comma-separated list of pattern=N settings for file-filtered logging

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.
