1 year ago I have since discovered you can mount configuration over a volume mount. You do need to provide a subPath and specify the mounting file name and it does indeed work as expected.
Adding my config as an example:

Description
I am struggling to run the on-premises version of the application in our kubernetes strack. And it's because the properties file is nested in the data directory.
I want to manage the config via configmap, and mount it to a filepath. And my data directory to be a volume mount. But you cannot mount a config map to disk over a volume mount.
Something simple to fix this would be to provide a way to point to the properties file outside of the data directory. Or alternatively, make all options available via ENV variable.
Steps to reproduce
Use both a volume mount and configmap.
