Kubernetes - does not start the role of master

Question

I'm starting a Kubernetes cluster of 3 nodes (1 master, 2 worker)

Trying to go by steps described in Ansible playbook - https://gitlab.com/LinarNadyrov/gcp/tree/master

Applying playbook steps 1,2,3 consequentially

After than, I connect to master to check status:

NAME STATUS ROLES AGE VERSION

master NotReady master 17m v1.13.0

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Status is NotReady

Could anyone help me with it? What's the problem? What should be done to fix it? Maybe I missed something?

Thanx in advance!
