nvidia-docker : Got permission denied

Question

Docker newbie question here, so please be nice.

I know this might be asked before but I could not find anything related to nvidia-docker. I completed the installation instructions on the official guide.

When I wanted to test Nvidia-docker:

docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

I got this error:

(base) user@adminme:~$ docker run --gpus all --rm nvidia/cuda nvidia-smi
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/create: dial unix /var/run/docker.sock: connect: permission denied.
See 'docker run --help'.

I found this answer here, but it felt a bit different for my case. I am very new to docker and still learning. let me know what you think?

here is some information about my remote Linux machine:

(base) user@adminme:~$ lspci | grep -i nvidia
02:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1080] (rev a1)
02:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller (rev a1)

nvidia-smi command:

(base) user@adminme:~$ nvidia-smi

Do the solutions in the answer you linked to work for you? How is your situation different? (That should resolve the `/var/run/docker.sock: permission denied` problem.) — David Maze, May 31 '20 at 10:45
it is not just sudo, You can do as the answers said to avoid having to use sudo with docker — KansaiRobot, Jul 02 '20 at 00:20

The quick fix would be to run the container using sudo:

sudo docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

If you want to run docker as non-root user then you need to add it to the docker group.

Create the docker group if it does not exist

sudo groupadd docker

Add your user to the docker group.

sudo usermod -aG docker $USER

Run the following command or Logout and login again and run (that doesn't work you may need to reboot your machine first)

newgrp docker

Check if docker can be run without root

docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

In addition to what nischay goyal answered, sometimes after adding the user to the docker group you have to do

su - ${USER}

in order to log out and log back.
