Deploying a stack via github

I’ve set up Portainer on my Synology DSM. Thinks seem to be running fine. I want to try to install a stack with a docker-compose.yml file. It seems a couple of the containers build OK, but the containers that rely on other files within the git repo fail.

For example, one container copies an init sql file to postgres and the container fails to start because it can’t find that file.

Where does portainer store the checked out git files? It looks like it is mapping files in data/compose/... but I don’t see where this exists on my synology.

This is the repo I’m trying to set up

Git repos are cloned inside the portainer container, of if you have set up a persistent volume they will be cloned inside that
