How to do a simple reboot with ansible and resume the playbook ?

May be you know, I do some tutorials in devops world.

Recently I start a playlist about ansible, a great tool for the infrastructure as code. This is an beginners playlist to learn step by step to understand and use it.

In a new video, I explain how to use the reboot module, a very simple but powerfull module. With it, you can reboot a server. But ansible can restart the server and check it after the reboot and resume the playbook to do the rest of tasks.

This is very useful, for example, to do a dist upgrade or kernel upgrade who need a reboot after.

For example, you can do it like this :

- name: update cache
      apt:
        update_cache: yes
        force_apt_get: yes
        cache_valid_time: 3600

    - name: dist upgrade
      apt:
        upgrade: dist
        force_apt_get: yes

    - name: check the reboot-required file
      register: reboot_required_file
      stat:
        path: /var/run/reboot-required
      register: reboot_required_file

    - name: launch the reboot
      reboot:
        msg: "Reboot with ansible..."
        connect_timeout: 5
        reboot_timeout: 300
        pre_reboot_delay: 0
        post_reboot_delay: 30
        test_command: uptime
      when: reboot_required_file.stat.exists
