Auto-Check & Flag n8n Version Updates Daily

This n8n workflow automates the monitoring of your self-hosted n8n instance's version, specifically designed for Docker on Ubuntu. It triggers daily at 5:00 AM via Schedule Trigger, fetches the latest stable version from the npm registry using an HTTP Request to https://registry.npmjs.org/n8n/latest, and retrieves the current local version from your n8n instance's endpoint (e.g., http://192.168.10.x). A comparison logic then determines if an update is needed, writing 'true' to a check_update.txt flag file if outdated.

Benefits include effortless version tracking without manual checks, seamless integration with existing cron jobs (like update_n8n.cron running check-update.sh at 5:10 AM), and prevention of security vulnerabilities from outdated software. It saves admins hours weekly by automating a critical maintenance task.

Ideal use cases: Self-hosted n8n users on Docker wanting proactive updates, DevOps teams managing multiple instances, or agencies ensuring client environments stay current. Pair with custom update scripts in check-update.sh for full automation, supporting compose.yml restarts post-update.
