`linked` line not seen when deploying NodeJS app

[martin-hewitt]

I'm deploying a NodeJS app (Ghost) on dokku, and want to use the MariaDB plugin to provide persistent storage for it.

The plugin installs fine, and creates the right docker instance, which I can connect to from the host system.

The problem comes when I deploy my node app. In the docs, I don't see the following snippet when pushing up to dokku:

remote: -----> Deploying foo ...
remote: 
remote: -----> App foo linked to mariadb/foo database
remote:        DATABASE_URL=...

Because I don't get that link, I think my Node app is struggling to connect across containers, so I get a database timeout when it attempts to reach the MariaDB container.

Do I need to add some metadata to my node app to tell dokku that it's looking for a database container?
