Is there any more to the error message? This post suggests the file it is looking for is the PID file.
What you could do is to add a custom command line for this image, I think the key is command. Using that you can launch the server in a custom way. Perhaps it is trying to use a socket, and needs to use a TCP port instead?
Alternatively, if you are not wedded to using a secondary container for your database, you could see this post on installing the database server in the primary/build container.
