## kubectl label
Update the labels on a resource
### Synopsis
2015-03-11 17:22:08 +00:00
2015-01-31 19:08:59 +00:00
Update the labels on a resource.
2015-05-20 09:02:30 +00:00
A label must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters.
2015-01-31 19:08:59 +00:00
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.
2015-03-11 17:22:08 +00:00
```
2015-08-05 03:43:48 +00:00
kubectl label [--overwrite] (-f FILENAME | TYPE NAME) KEY_1=VAL_1 ... KEY_N=VAL_N [--resource-version=version]
