"content": "## n8n Auto-Updater via Coolify \ud83d\udd04\n\n### How it works\nThis workflow automatically checks whether your self-hosted n8n instance is outdated and triggers a redeployment via Coolify \u2014 no manual intervention needed.\n\n1. A weekly **Schedule** triggers the workflow.\n2. The **n8n Audit** node runs a security audit on your instance and checks for outdated versions.\n3. An **IF** node evaluates whether the audit flagged the instance as outdated.\n4. If outdated: the latest stable version is fetched from **GitHub**, then **Coolify** is called to restart the service with the new image.\n5. A **Mattermost** notification confirms the update.\n6. If up to date: the workflow stops silently.\n\n### Setup\n1. **n8n API Key** \u2014 Go to *Settings \u2192 API \u2192 Generate Key* and create an `n8n API` credential. Assign it to the **GET audit** node.\n2. **Coolify** \u2014 Generate an API token in Coolify (*Settings \u2192 API Tokens*). Create an `HTTP Bearer Auth` credential and assign it to the **CALL Coolify** node. Update the URL with your domain and service UUID.\n3. **Mattermost (optional)** \u2014 Replace the URL, Bearer token, and channel ID in the **post to channel** node. Or delete this node if not needed.\n4. **Schedule** \u2014 Default is weekly on Monday at 01:00. Adjust as needed."
