Installing invoice ninja on docker plesk ext

I am trying to install Docker Hub via the docker plesk extensions however it keeps failing and there are no instructions on what exactly I need to do.

The error initially was regarding connection to the DB so I added the variables to a DB i have created and now it says No such file or directory )sql: select *…
I am guessing that is because I set up an empty DB. I don’t even know where to begin to populate a database with the tables etc that invoice ninja requires. They have all of the guides to do this from terminal but I would like to do it all from within plesk.
