Question

Add label to nodes:

If I want to delete label(key1=val1) on node(10.xx.xx.xx), how

Answer 1

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)
