WickedBee96 , I think basically you need to find a way to use docker commands without requiring sudo before

Note that you might need to log out login or reboot the machine for the change to take effect

Normally it's an environment variable set to the current user, you can check by typing echo $USER in the terminal

I tried to run this command but still the same

looks like the user running your clearML agent is not added to the docker group

do I need to change USER (with my device name) or it is a keyword

Make sure you have entered the command
usermod -aG docker $USEROn the VM you are running your agent on
