I have an app that consists of 5 containers in Docker and docker-compose is used to automate the install and configuration. A configuration .env can be customized for most parameters one of which is the location on the windows file system where to read and write data used by the application.
My question is what would be the best way to handle the application specific read/write data location in kuberentes with the intentet of eventually moving the app to Azure.
