Watchtower automatically updates your Docker containers when new images are available. This workflow receives Watchtower's HTTP notifications and forwards them instantly to Telegram — so you always know when a container was updated.
Receives POST notifications from Watchtower whenever a Docker container is updated — no polling, instant delivery.
Each container update forwarded to Telegram with the update message and timestamp — you know within seconds.
Compatible with any Watchtower instance — just configure the HTTP notification URL to point to this n8n webhook.
Each alert includes the date the update occurred — building an automatic history of all container updates on your server.
The webhook is always listening — day or night, weekday or weekend. Container updates never go unnoticed.
Telegram message history becomes your container update log — searchable, timestamped and always accessible.
Watchtower monitors your Docker containers for new image versions. When one is found, it pulls and updates the container.
Watchtower sends a POST request to your n8n webhook URL with the update details — container name and update message.
The n8n webhook catches the notification immediately — no delay, no polling.
Formatted message sent to Telegram: "Watchtower update — [message] — [date]". You know which container was updated and when.
Know the moment any Docker container on your server is updated — important for production environments where updates matter.
Running n8n, Chatwoot, Ghost or any Dockerised app? Know when Watchtower updates them without checking server logs.
Simple, lean monitoring for your self-hosted stack — Watchtower updates happen while you sleep; this tells you in the morning.
We'll connect Watchtower on your server to this webhook — every container update forwarded to your Telegram instantly.
