[🚀 Feature]: Transparency on files written inside the docker containers

Feature and motivation

My organization is preventing spinning up containers without understanding where the files are written in the containers. Can we pls document all the files written inside the containers such that we can mount those folders where the files are written. I would recommend writing files only in the temp directory and not anywhere else to have a secured selenium HQ containers running.

Usage example

example: https://github.com/SeleniumHQ/docker-selenium/blob/trunk/NodeChromium/Dockerfile
When container is spin up, if there any files needs to be written by the jar or services, we need to write all the files only in /tmp folder and avoid writing any files after spin up inside the root folders including opt/bin/ etc..

Start with NodeChromium/Dockerfile and trace the JAR and services it starts to identify files written after container startup. Document each written path and indicate which paths can be mounted or moved to /tmp; done means the container file-write locations and the requested storage guidance are documented.
