Question

I am trying install flannel on master node and getting below error.

You must be using Kubernetes version >=1.16. DaemonSet in extensions/v1beta1 is deprecated..

Use apps/v1 api group instead.

Try using https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml.
