Automatically Updating Containers on Synology Docker with Watchtower

Automatically update containers on Synology Docker using Watchtower.

Downloading the Image in Synology Docker Application

Open the Synology Docker package and download the containrrr/watchtower image.

Configuring Watchtower in Task Scheduler

Navigate to Synology's Control Panel - Task Scheduler - Create - Scheduled Task - User-defined script. Then, fill in the configuration as shown in the images below:

The script in question is as follows:

docker run --rm --name watchtower -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower --cleanup --run-once calibre-web freshrss code-server

Please note that the last part of the script, "calibre-web freshrss code-server," represents the names of the containers to be updated. You should replace these with the names of the containers you wish to update, or leave it blank to update all containers.

Save and execute the script to achieve batch scheduled updates of Docker containers.
