Setup Watchtower

Overview

A process for automating Docker container base image updates.

Changelog

2025-01-26

• Added Socket Proxy so Watchtower is not interacting with the docker socket directly
• Changed Networks to the new network scheme (Main/Internal) instead of (Proxy/Internal).
• Removed API Access from Watchtower as it isn't really needed and i wont be monitoring it anymore.
• Fixed the connection between socket-proxy and watchtower.
• Verified it is working properly to auto update the containers and remove previous images.
