​
✅ Check /data is owned by root
root# ls -al /data
total 24
drwxr-xr-x 3 root root  4096 Jan 19 12:54 .
drwxr-xr-x 1 root root  4096 Jan 19 12:57 ..
drwx------ 2 root root 16384 Jan 19 12:54 lost+found




✅ Create demo user
groupadd demo
useradd demo -g demo -m


✅ Give /data to demo user
chown demo:demo /data


✅ Prove we can use a user that only exists in this pod
su - demo -c whoami
demo


✅ Run a command as another user
root# su demo -c "touch /data/myfile"


✅ See a resulting file owned by the other user (which doesn't exist in the "hypervisor")
root# ls -al /data
total 24
drwxr-xr-x 3 demo demo  4096 Jan 19 13:01 .
drwxr-xr-x 1 root root  4096 Jan 19 12:57 ..
drwx------ 2 root root 16384 Jan 19 12:54 lost+found
