Automated n8n Update & Notification Workflow

This n8n workflow automates the process of checking for the latest n8n updates, pulling new Docker images, and updating the running container seamlessly. It begins with scheduled checks or manual triggers to gather current installed versions from the server and compare them with the latest release available on GitHub. If a new version is detected, the workflow sends Telegram notifications to approve the update. Upon confirmation, it pulls the latest Docker image, performs Docker Compose operations to update and restart the container, and sends a final notification indicating the successful update. This workflow is ideal for maintaining n8n environments with minimal manual intervention, ensuring the system stays up to date automatically while providing clear communication channels through Telegram.
