Synology: 30 Second Watchtower Install Using Task Scheduler & Docker

Synology 30 Second Watchtower Install Using Task Scheduler & Docker

Do you want to install Watchtower via Docker without a terminal? Are you tired of complicated guides? Do you want something quick and easy? Well today I will teach you how to install Watchtower on your Synology NAS in less than 30 seconds directly through the Task Scheduler option. It’ll be over in a couple of seconds and it’s essentially child’s play. With Watchtower you can update the running version of your docker container app simply by pushing a new image to the Docker Hub or your own image registry. Watchtower will pull down your new image, gracefully shut down your existing container and restart it with the same options that were used when it was deployed initially.

Note: This guide works perfectly with the latest Watchtower v1.3.0 release.
