How to reboot CentOS 7 with Ansible?

Question

I\'m trying to reboot server running CentOS 7 on VirtualBox. I use this task:

- name: Restart server
  command: /sbin/reboot
  async: 0
  poll:

I am using Ansible 2.5.3. Below code works with ease,

- name: Rebooting host
  shell: 'shutdown -r +1 "Reboot triggered by Ansible"'

- wait_for_connection:
    delay: 90
    timeout: 300

You can reboot immediately, then insert a delay if your machine takes a while to go down:

    - name: Rebooting host
      shell: 'shutdown -r now "Reboot triggered by Ansible"'
      async: 1
      poll: 1
      ignore_errors: true

# Wait 120 seconds to make sure the machine won't connect immediately in the next section.
    - name: Delay for the host to go down
      local_action: shell /bin/sleep 120

Then poll to make the playbook return as soon as possible:

    - name: Wait for the server to finish rebooting
      wait_for_connection:
        delay: 15
        sleep: 15
        timeout: 300

This will make the playbook return as soon as possible after the reboot.
