kubectl label
Synopsis
Update the labels on a resource.
- A label key and value must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters each.
- Optionally, the key can begin with a DNS subdomain prefix and a single '/', like example.com/my-app.
- 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] (-f FILENAME | TYPE 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 a pod identified by the type and name in "pod.json"
kubectl label -f pod.json 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-
