Shiny docker: Can't connect to local MySQL server through socket

Hi,
I've used a golem pipeline to package & dockerize my app. For starters, I am trying to deploy the app locally on windows pc using docker. The app collects the data from a local SQlite database also running on my pc (which will be similar once deployed on a server).
When I run the app as a package, app functions alright.
But once I create a docker image & run it, the app launched but is unable to connect to my local sql database, returning this error:

Warning: Error in connection_create: Failed to connect: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")

Any help greatly appreciated!
