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:          


        

Answer 1

Following solution works for me perfect:

- name: Restart machine
  shell: "sleep 5 && sudo shutdown -r now"
  async: 1
  poll: 0

- name: wait for ssh again available.
  wait_for_connection:
    connect_timeout: 20
    sleep: 5
    delay: 5
    timeout: 300

Sleep is required because ansible requires few second's to wrap up connection. Excelent post about this problem was written here: https://www.jeffgeerling.com/blog/2018/reboot-and-wait-reboot-complete-ansible-playbook
