Fix our envs setup in regards to the docker compose file.

Currently, in our code we load manually our env vars from the path. But since the path is a virtual path once in a docker container, we need to copy paste the env into the container image. This is not a good practice.

I'll rather let docker compose inject those envs for each container as command line arguments upon each startup, this way we do not inject the env to the image, and we should not use vpaths scanning anymore !
