if $count == $total
  File.open('.hosts.yml', 'w') { |f| f.write host_vars.to_yaml }
  box.vm.provision "ansible" do |ansible|

    end
    ansible.become = true
    ansible.limit = "all,localhost"
    ansible.host_key_checking = false

Issues was added 2 days ago by @mboglesby in roles/kubernetes/client/tasks/main.yml. My fix - doesn't fix anything. Please ignore it. Wholdn't it be easier just to use copy module instead synchronize?

@butuzov - I just submitted PR #5120 to revert the change from the fetch to the synchronize module that I made with #5084. Changing to synchronize created more problems than it solved.
