Having been tinkering with the taint function on an x86 node in an IBM Kubernetes Service (IKS) cluster, to force my pods to deploy onto another node in the same cluster: -
kubectl taint node node1 node1=DoNotSchedulePods:NoExecute
kubectl taint node node1 node1=DoNotSchedulePods:NoExecute
I was looking for an easy way to reverse the taint ( "untaint" ), and found this: -
kubectl patch node node1 -p '{"spec":{"taints":[]}}'
with thanks to this: -
