Ansible role to shutdown a server after the work is done.

This role installs a systemd service with timer that monitors a server for activity and shuts it down after it has been idling for a specific period. Ideal for special-purpose servers with few users, like my deep learning/blender server.

Features

This ansible role:

• uses systemd timers to periodically
• monitor ssh connections, CPU and GPU load
• shuts down the server when it is idling too long

Suitable for headless servers.

Example playbook

- hosts: all

  vars:
    shutdown_on_idle_max_idle_time: 1800

  roles:
    - victorklos.shutdown-on-idle

Supported role variables

See example playbook above, default value as indicated.

Notes

Remember to also kick inactive ssh users or otherwise the host will never be considered idle.

You can see what is going on by issueing one of these:

systemctl status shutdown_on_idle.timer             # the timer part
systemctl status shutdown_on_idle.service           # the monitoring part
journalctl --boot --unit=shutdown_on_idle.service   # all logs since boot
