I'm new to Traefik. I'm trying to develop a plugin and "connect" it to my webserver using Docker Compose. I use docker compose for development. When I try to run the Docker Compose I encountered this error:
/dev/echo-docker-compose $ docker-compose up --build
Starting echo-server ... done
Recreating traefik ... done
Attaching to echo-server, traefik

I think I can conclude that the cause of this error is that it can't find the .traefik.yml file which is quite obvious. But, I already have the file in that directory.
This is my full directory structure
dev/plugins-local/

└── github.com

For some reasons, I think Docker Compose can't read .traefik.yml. But, it's also the same case when I try to run ./traefik --configfile traefik-plugin.yml from dev/plugins-local. It also throws the same error where it can't read the .traefik.yml.
Anyone knows how to fix this problem?
