Linking solr config from app?

[cwant]

Sorry if this is more of a question than an issue (but I am neither a solr or a Dokku expert, and Google is not my friend searching for this one) ...

I have a Rails Dokku app called training. It has a solr directory to configure a solr service (usually done using docker-compose by mounting a directory).
I have created and linked a dokku-solr service called training-solr. The Dokku app and solr service are linked as per the documentation.

My question: is it possible for the solr service to get it's config from a directory in the app container?

Responded to here but:

• You need to put the config in a top-level solr folder.
• There is no subfolder, the config has to be in that folder as is.
• It is copied during the post-extract phase of an app deploy.
