Permissions issue in Linux

Output from installing docker in linux using the script

docker@8fc17e294469:~/docker_work$ mkdir test
mkdir: cannot create directory 'test': Permission denied

>>> Why is docker_work protected? What is the password?

Start by reviewing the Linux installation script and how it creates or mounts docker_work, then inspect permissions inside the evbauer/mesa_lean:15140.01 container. Reproduce mkdir test in docker_work and record which user owns the directory and whether the behavior is documented. Done means the cause and expected access behavior are clear.
