To remove for all nodes "kubectl label --all -" – Hem Feb 08 '18 at 21:10

For more than one node "kubectl label -" – Hem Feb 08 '18 at 21:17

@Hem nice, but shouldn't it be "kubectl label nodes --all -"? For me that did work at least. – Nicolas Mommaerts Sep 11 '18 at 08:47
@NicolasMommaerts, well, if you'd like to do it for all nodes, not a subset. – Hem Sep 11 '18 at 18:46

@Hem, no I meant it seems you forgot the word 'nodes' in both your examples. You need to specify you want to label a node (or some other type of resource). – Nicolas Mommaerts Sep 12 '18 at 20:23
@NicolasMommaerts, yeah I you're right. Unfortunately, SO does not allow me to edit. – Hem Sep 13 '18 at 18:25

Below command worked for me to remove label:

kubectl label node <nodename> <label>-

Note: The syntax is a minus sign directly after the key. For example, if the node name is worker1 and the label is system=workernode, you can remove a label with the following command.

kubectl label node worker1 system-

From kubectl label -h:

Update pod 'foo' by removing a label named 'bar' if it exists.
Does not require the --overwrite flag.
$ kubectl label pods foo bar-

The same works for nodes.

To add a label to kubernetes nodes:

kubectl label node "your-node-name" node-role.kubernetes.io/worker=worker

To remove a label from kubernetes nodes:

kubectl label node "your node-name" node-role.kubernetes.io/worker-

Note: To remove a label put a "-" symbol at the end of your label name

This worked for me. Add Label

kubectl label node <node name> node-role.kubernetes.io/<role name>=<key - (any name)>

Remove label

kubectl label node <node name> node-role.kubernetes.io/<role name>-

As already mentioned, correct kubectl example to delete label, but there is no mention of removing labels using API clients. if you want to remove label using the API, then you need to provide a new body with the labelname: None and then patch that body to the node or pod. I am using the kubernetes python client API for example purpose

from pprint import pprint
from kubernetes import client, config

config.load_kube_config()
client.configuration.debug = True

api_instance = client.CoreV1Api()

body = {
    "metadata": {
        "labels": {
            "label-name": None}
        }
}

api_response = api_instance.patch_node("minikube", body)

print(api_response)

You can remove the label from a single node using the following kubectl command

kubectl label node 10.xx.xx.xx Key1-

If you want to remove the label for all the nodes, use the following command

kubectl label nodes --all Key1-

to verify and compare with other nodes

kubectl get nodes
kubectl get nodes --show-labels

When I did this it responded with a comforting and affirming `namespace/X unlabeled`. – Josiah Apr 27 '23 at 04:08
it seems the sessions in this site works in some weird way, my response belongs to another thread I had open too, for marking node as worker – David May 05 '23 at 16:43

If you want to see existing labels for the nodes kubectl get nodes --show-labels
Then, list the key_name and node_name you want to modify
Then, kubectl label node node_name key_name-
