Env file flag not working

[rimelek (Ákos Takács)]

The --env-file is not for setting variables in container,s but for setting variables that you can refer to in a compose file. It is basically an alternative .env file.

We discussed it couple of times like here

Specifying buildtime envars for docker-compose with multitiple files

The title is a little bit misleading, since you from the Docker Compose point of view you don’t want builtime environment variables (build args), only different variables for the submodules without the user knowing you there are additional variables. --env-file as a parameter of docker compose is not the same as env_file in the yaml block of a service. --env-file is just an alternative of .env without specifying it for any service so Docker Compose could make those variables available as place…

You can search for --env-file on the forum for more posts.
