Thanks @adoroszlai for the patch. Please check the inline comment?

Is it recommended ./docker-config or docker-config?

[adoroszlai]

./ is required for volumes in the current directory ("to avoid ambiguities with named volumes, relative paths should always begin with . or .."). There is no such ambiguity with env_file, so the form docker-config is recommended for simplicity.
