Have you tried using the absolute path for the additional file instead of a relative one? It might help resolve the issue. Good luck!
Portainer
Portainer Community Edition is a lightweight service delivery platform for containerized applications that can be used to manage Docker, Swarm, Kubernetes and ACI environments.
I did. Usually I never use a relative way to describe the patch. But thanks for suggesting it.
I have no luck any ay on Portainer with netbox. I have cloned the repo , and edited the compose file an till having trouble with it. Seem that there is more external things going on behind the scenes not in the containers itself but externally until all is set. and this causes this problem. I have been stuck with the problem that dependencies between the containers fall as it seems to wait for wrong names but the compose file doesn't allow changing names. and because it does use there same containers it automatically renames spending the container name with the number 1 at the end. and seems that the dependents don't understand it. I'm not sure where to find the real logs but I; 'm reading from pop-up messages on Portainer.
