Automate Docker Updates with Telegram Approval

This workflow streamlines Docker container maintenance for DevOps teams and sysadmins. It uses a cron trigger to periodically fetch the latest image version from GitHub, compares it against the running container version on the server via SSH, and notifies via Telegram if an update is available, awaiting user approval.

Upon confirmation, it executes Docker commands over SSH to pull the new image, update the container (e.g., via docker-compose), and restart it seamlessly. Post-update, it sends a success notification. This prevents downtime from unapproved changes and ensures controlled updates.

Benefits include time savings on manual checks, reduced human error, and audit trails via Telegram. Use cases: Updating self-hosted n8n instances every few days, managing production Docker apps, or any GitHub-hosted Docker image in automated environments. Customizable for other tools like Slack or additional validations.
