What Changed
#

Upgraded Watchtower notifications from plain text to Discord embeds using Shoutrrr URL parameters:

  • Added colored sidebar (green for updates)
  • Suppressed noisy startup messages
  • Cleaner, more readable notifications

Why
#

Plain text Watchtower notifications were hard to scan in busy Discord channels. Embeds provide visual structure and color-coding.

Details
#

Updated WATCHTOWER_NOTIFICATION_URL across all Docker Compose stacks:

environment:
  - WATCHTOWER_NO_STARTUP_MESSAGE=true
  - "WATCHTOWER_NOTIFICATION_URL=discord://<WEBHOOK_ID>/<WEBHOOK_TOKEN>?color=5793266&title=Watchtower:+ServiceName"

Key parameters:

  • color=5793266 - Green sidebar (hex #588532 as decimal)
  • title=Watchtower:+ServiceName - Clear source identification
  • WATCHTOWER_NO_STARTUP_MESSAGE=true - Prevents “Watchtower started” spam

Result
#

Discord notifications now show as clean embeds with green sidebar. Startup noise eliminated. Rolled out to all services with Watchtower.
