## kubectl label
|
|
|
|
Update the labels on a resource
|
|
|
|
### Synopsis
|
|
|
|
|
|
Update the labels on a resource.
|
|
|
|
If --overwrite is true, then existing labels can be overwritten, otherwise attempting to overwrite a label 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.
|
|
|
|
```
|
|
kubectl label [--overwrite] RESOURCE NAME KEY_1=VAL_1 ... KEY_N=VAL_N [--resource-version=version]
|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
// Update pod 'foo' with the label 'unhealthy' and the value 'true'.
|
|
$ kubectl label pods foo unhealthy=true
|
|
|
|
// Update pod 'foo' with the label 'status' and the value 'unhealthy', overwriting any existing value.
|
|
$ kubectl label --overwrite pods foo status=unhealthy
|
|
|
|
// Update all pods in the namespace
|
|
$ kubectl label pods --all status=unhealthy
|
|
|
|
// Update pod 'foo' only if the resource is unchanged from version 1.
|
|
$ kubectl label pods foo status=unhealthy --resource-version=1
|
|
|
|
// Update pod 'foo' by removing a label named 'bar' if it exists.
|
|
// Does not require the --overwrite flag.
|
|
$ kubectl label pods foo bar-
|
|
```
