reboot_handler

Handle reboot notification, reboot remote UNIX/Linux machines and wait them back.

This handler listens a message of "reboot system", provides variables to skip reboot or skip the confirmation before rebooting.

Requirements

• Ansible >= 2.2, we are listen the notifications
• jinja2 >= 2.6
• permissions to become root
• remote machines must be rebootable via shutdown or reboot commmands
• the connections of remote machines must be in ssh, smart, paramiko or funcd

Role Variables

Variable skip_reboot, default True. This variable should be defined in host/group vars. The reboot action is dangerous in many situations, so we will not reboot the machine unless the skip_root for a inventory_hostname is set to True.

Variable reboot_confirm, default True. if set to True, the handler will trigger a prompt once for a batch, the prompting message contains the list of rebooting machines in this batch. Press Ctrl+C and A to abort the playbook, or press Enter key to continue.

Dependencies

• role gzm55.require_implicity_localhost
• role gzm55.require_disabe_become
• role gzm55.local_id_plugin
• role gzm55.require_become_root

Example Playbook

- hosts: servers
  roles:
  - { role: user.reboot_handler, reboot_confirm: True }
  tasks:
  - name: change system
    raw: 'true'
    notify: "reboot system"

Developing

The testing progress is based on molecule with vagrant driver which is not supported by travis-ci. So in each release, we have to run molecule test on a developing machine, and then galaxy import manually.

TODO: use wait_for_connection module (ansible >= 2.3) to wait machines comming back.
