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

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

I tried to run this command but still the same

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

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

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

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