log4cxx logger modification in docker container

Question

I have a c++ application that uses log4cxx for logging. log4cxx configuration will be done via XML file where the logging level and different loggers can be enabled and disabled. with installation running in VM it was easy to make the necessary modifications as needed by getting into VM and changing the XML file manually. but now we are going to run the application as a docker image which will run in the cloud, so the question is how to make modifications around the logger level as and when needed. I did try to search for this before asking here, but the solutions which are mentioned are java based, like spring boot admin, etc. which is not suitable here.
