Overview

Add a Taint

kubectl taint nodes docker-desktop is_control=true:NoExecute

Remove a Taint

kubectl taint nodes docker-desktop is_control=true:NoExecute-

Example

apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: fluentd-elasticsearch
  namespace: kube-system
  labels:
    k8s-app: fluentd-logging
spec:
  selector:
    matchLabels:
      name: fluentd-elasticsearch
  template:
    metadata:
      labels:
        name: fluentd-elasticsearch
    spec:

      tolerations:
      - key: "is_control"
        operator: "Equal"
		value: "true"
        effect: "NoExecute"

      containers:
      - name: fluentd-elasticsearch
..

The above toleration will allow the pod to be deployed on a node with a matching taint.
