How to wait for server restart using Ansible?

Question

I\'m trying to restart the server and then wait, using this:

- name: Restart server
  shell: reboot

- name: Wait for server to restart
  wait_for:
    port=

In case you don't have DNS setup for the remote server yet, you can pass the IP address instead of a variable hostname:

- name: Restart server
  command: shutdown -r now

- name: Wait for server to restart successfully
  local_action:
    module: wait_for
      host={{ ansible_default_ipv4.address }}
      port=22
      delay=1
      timeout=120

These are the two tasks I added to the end of my ansible-swap playbook (to install 4GB of swap on new Digital Ocean droplets.
