Certbot Reaper

Description

This Ansible role automates the detection, revocation and deletion of unused Let’s Encrypt certificates. It leverages the certreap tool to identify certificates no longer referenced by any active NGINX configuration and removes them automatically.

Overview

  • Installs the certreap cleanup tool using the pkgmgr-install role

  • Deploys and configures a systemd unit

  • (Optionally) Sets up a recurring cleanup via a systemd timer using the sys-timer role

  • Integrates with sys-ctl-alm-compose to send failure notifications

  • Ensures idempotent execution with a run_once_sys_ctl_cln_certs flag

Features

  • Certificate Cleanup Tool Installation
    Uses pkgmgr-install to install the certreap binary.

  • Systemd Service Configuration
    Deploys service and reloads/restarts it on changes.

  • Systemd Timer Scheduling
    Optionally wires in a timer via the sys-timer role, controlled by the on_calendar_cleanup_certs variable.

  • Smart Execution Logic
    Prevents multiple runs in one play by setting a run_once_sys_ctl_cln_certs fact.

  • Failure Notification
    Triggers service on failure.
