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=

Through trial and error + a lot of reading this is what ultimately worked for me using the 2.0 version of Ansible:

$ ansible --version
ansible 2.0.0 (devel 974b69d236) last updated 2015/09/01 13:37:26 (GMT -400)
  lib/ansible/modules/core: (detached HEAD bbcfb1092a) last updated 2015/09/01 13:37:29 (GMT -400)
  lib/ansible/modules/extras: (detached HEAD b8803306d1) last updated 2015/09/01 13:37:29 (GMT -400)
  config file = /Users/sammingolelli/projects/git_repos/devops/ansible/playbooks/test-2/ansible.cfg
  configured module search path = None

My solution for disabling SELinux and rebooting a node when needed:

---
- name: disable SELinux
  selinux: state=disabled
  register: st

- name: reboot if SELinux changed
  shell: shutdown -r now "Ansible updates triggered"
  async: 0
  poll: 0
  ignore_errors: true
  when: st.changed

- name: waiting for server to reboot
  wait_for: host="{{ ansible_ssh_host | default(inventory_hostname) }}" port={{ ansible_ssh_port | default(22) }} search_regex=OpenSSH delay=30 timeout=120
  connection: local
  sudo: false
  when: st.changed
