## 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.

Possible resources include (case insensitive): pods (po), services (svc),
replicationcontrollers (rc), nodes (no), events (ev), componentstatuses (cs),
limitranges (limits), persistentvolumes (pv), persistentvolumeclaims (pvc),
resourcequotas (quota) or secrets.

```
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[=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
      --overwrite[=false]: If true, allow annotations to be overwritten, otherwise reject annotation updates that overwrite existing annotations.
      --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.
```
