Automated n8n Update Checker

• DevOps Engineers: Those responsible for maintaining and updating n8n instances.
• System Administrators: Individuals who manage server environments and need to ensure applications are up-to-date.
• Automation Enthusiasts: Users who want to automate the process of checking and updating n8n versions.
• Telegram Bot Developers: Developers who want to integrate notifications into their workflows for version updates.

This workflow automates the process of checking for the latest version of n8n and updating the Docker image if a new version is available. It ensures that users are always running the latest version, which can include important features, bug fixes, and security patches. This reduces manual intervention and the risk of running outdated software.

• Set Default Variables: It initializes necessary variables such as the working directory and n8n container name.
• Check Installed Version: The current version of n8n is fetched from the Docker container.
• Fetch Latest Version: A request is made to the n8n GitHub repository to get the latest released version.
• Compare Versions: The installed version is compared with the latest version.
• Notification: If the versions match, a Telegram notification is sent to inform that n8n is up-to-date.
• Approval for Update: If a new version is available, a Telegram message asks for user approval to proceed with the update.
• Pull Latest Image: Upon approval, the latest n8n Docker image is pulled.
• Update Docker Compose: The workflow pulls the latest services defined in the Docker Compose file and then starts the updated container.
• Final Notification: A final Telegram message is sent to confirm that n8n has been successfully updated.
