Hi,
I am using the k8sMaster.sh to setup the kubernetes.
Whenever I apply the calico.yaml file the networking plugin is not getting applied with the following error:

Ok, got it working. I had not seen the latest document. Thanks
@abhijitherekar I'm currently troubleshooting same issue. How did you get it to work?
****As of v1.12.1 with the early October version of Calico new nodes now have another taint,
node.kubernetes.io/not-ready:NoSchedule. We need to remove this taint so that the scheduler will begin to allocate
Calico pods to both nodes. They need to be running prior to nodes showing Ready. As of this writing the taint
removal may take two or three times to work. Wait a minute, view taints and run the command again until the taints
are removed.****

Taints: node.kubernetes.io/not-ready:NoSchedule
Taints: node.kubernetes.io/not-ready:NoSchedule

kubectl taint nodes --all node.kubernetes.io/not-readynode/ckad-1

taint "node.kubernetes.io/not-ready:" not found
take a minute or two for all pods to enter Ready state.
