Traefik container has no mount on docker inspect - docker

Question

I have an error that only happens when I run docker compose up on one of my docker compose files and not the other, even though the services named "proxy" in which the error occurs are identical.
When I run docker compose -f docker-compose-v1.yml up -d the containers start without issue but on inspection the container named github_proxy_1 has no mounts.
If I run docker-compose -f docker-compose-v2.yml up -d the containers start without issue and on inspection the container named github_proxy_1 has mounts.
The proxy services are based on traefik windows images. I have read that many have had issues with binding volumes so that traefik can communicate with the underlying host, but the weird thing is that it works flawlessly in one setup but not the other.
Below are my docker version info, docker compose files, the results when inspecting the containers (showing the difference in mounts), and the error message from the container log shown in Docker Desktop.
Why does one proxy container manage to populate mounts while the other doesn't?
Thanks in advance!

Answer 1

So I found the problem. I was using docker-compose (using the docker-compose binary) for the compose that worked and docker compose for the one that didn't.
The question remains why one works and the other doesn't, what is the difference of running docker-compose vs docker compose? Does it perhaps somehow have to do with permissions?
