Who is this for? This workflow is for DevOps engineers, system administrators, and Docker users who want to automate the process of checking for updates, verifying them, and applying updates to their Docker-based deployment in a controlled manner. For example, this workflow is used to update the n8n Docker image. What does this workflow do? Fetches the latest Docker image version from GitHub. Compares it with the currently running version on the server. Sends a Telegram message requesting confirmation if an update is available. If confirmed, pulls the latest n8n Docker image, updates the container, and restarts it. Sends a Telegram message confirming the update is completed. Schedules automatic checks, Uses a cron trigger in n8n to check for updates at regular intervals. Setup Ensure n8n is installed and running in a Docker container. Create a Telegram bot using BotFather. Set up Telegram credentials. Set up SSH credentials (ensure the SSH user has sudo access). Obtain the bot token and chat ID. Set the Default variable node telegram-id (You can find it by messaging @get_id_bot). n8n-container-name (Specify the name of the n8n container.)
