kubectl annotate(1) 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): pods (po), services (svc), replicationcontrollers (rc), nodes (no), events (ev), componentstatuses (cs), limitranges (limits), persistentvolumes (pv), persistentvolumeclaims (pvc), horizontalpodautoscalers (hpa), resourcequotas (quota) or secrets.

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.
