Install nvidia driver and cuda on your host.
Get the Docker Daemon to run using lxc
We need to run docker daemon using lxc driver to be able to modify the configuration and give the container access to the device.
One time utilization :
sudo service docker stop
sudo docker -d -e lxc
Permanent configuration Modify your docker configuration file located in /etc/default/docker Change the line DOCKER_OPTS by adding '-e lxc' Here is my line after modification
DOCKER_OPTS="--dns 220.127.116.11 --dns 18.104.22.168 -e lxc"
Then restart the daemon using
sudo service docker restart
How to check if the daemon effectively use lxc driver ?
The Execution Driver line should look like that :
Execution Driver: lxc-1.0.5
Build your image with the NVIDIA and CUDA driver.
Run your image.
First you need to identify your the major number associated with your device. Easiest way is to do the following command :
ls -la /dev | grep nvidia
To activate lxc driver
--lxc-conf='lxc.cgroup.devices.allow = c [major number]:[minor number or *] rwm'
To launch a container, use the following command
Docker run -ti --lxc-conf='lxc.cgroup.devices.allow = c 195:* rwm' --lxc-conf='lxc.cgroup.devices.allow = c 243:* rwm' cuda
