Here you will find a collection of docker-compose's for Synology related to TRaSH-Guides.
Search in the templates folder for the application you want and copy/paste it in to your docker-compose.yml
in the <application>.yml file you will also find the command you need to use in a program like putty to create the correct appdata folder for your docker /config
I made use of DockSTARTer as base for the the templates.
