Problem 

User removed taint mode from the master using the following command

kubectl taint nodes iac-k8s-rp-ld0 node-role.kubernetes.io/master-

and wants to adds it back so pods will not schedule on the master

run the following command to taint the master  node

kubectl taint nodes <NODE NAME> node-role.kubernetes.io/master:NoSchedule

 

additional settings may be required to apply

kubectl taint nodes <NODENAME> key1=value1:NoSchedule

kubectl taint nodes <NODENAME> key1=value1:NoExecute

kubectl taint nodes <NODENAME> key2=value1:PreferNoSchedule
