kubectl annotate
Update the annotations on a resource
Synopsis
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.
Valid resource types include: * clusters (valid only for federation apiservers) * componentstatuses (aka ‘cs’) * configmaps (aka ‘cm’) * daemonsets (aka ‘ds’) * deployments (aka ‘deploy’) * events (aka ‘ev’) * endpoints (aka ‘ep’) * horizontalpodautoscalers (aka ‘hpa’) * ingress (aka ‘ing’) * jobs * limitranges (aka ‘limits’) * nodes (aka ‘no’) * namespaces (aka ‘ns’) * petsets (alpha feature, may be unstable) * pods (aka ‘po’) * persistentvolumes (aka ‘pv’) * persistentvolumeclaims (aka ‘pvc’) * quota * resourcequotas (aka ‘quota’) * replicasets (aka ‘rs’) * replicationcontrollers (aka ‘rc’) * secrets * serviceaccounts (aka ‘sa’) * services (aka ‘svc’)
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
-f, --filename value Filename, directory, or URL to a file identifying the resource to update the annotation (default [])
--include-extended-apis If true, include definitions of new APIs via calls to the API server. [default true] (default true)
--no-headers When using the default or custom-column output format, don't print headers.
-o, --output string Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
--output-version string Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
--overwrite If true, allow annotations to be overwritten, otherwise reject annotation updates that overwrite existing annotations.
--record 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 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
-a, --show-all When printing, show all resources (default hide terminated pods.)
--show-labels When printing, show all labels as the last column (default hide labels column)
--sort-by string 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 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].
Options inherited from parent commands
--alsologtostderr value log to standard error as well as files
--as string Username to impersonate for the operation
--certificate-authority string Path to a cert. file for the certificate authority

--password string Password for basic authentication to the API server
-s, --server string The address and port of the Kubernetes API server
--stderrthreshold value logs at or above this threshold go to stderr (default 2)
--token string Bearer token for authentication to the API server

-v, --v value log level for V logs
--vmodule value comma-separated list of pattern=N settings for file-filtered logging
