Command used to invoke ansible:
ansible-playbook -i inventory/mycluster/hosts.ini cluster.yml

Output of ansible run:
TASK [kubernetes/preinstall : Stop if swap enabled] ************************************************************************

It looks like ansible cluster creation playbook is failure in this step. Can you please look into this issue?

Easy workaround in lieu of repairing the role:
ansible all -i inventory/mycluster/hosts.ini -m mount -a "name=swap fstype=swap state=absent" && ansible all -i inventory/mycluster/hosts.ini -a "/sbin/swapoff -a"

I get crash at this point with ubuntu hosts as well. Looks like I just have to comment out this check
