Editing NVIDIA Docker Runtime

(originally from https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html#docker)

== CentOS 7/8 ==
<pre>sudo yum-config-manager --add-repo https://nvidia.github.io/nvidia-docker/centos7/x86_64/nvidia-docker.repo
sudo yum install -y nvidia-docker2</pre>

== Debian 10 ==
Setup the stable repository and the GPG key:
<pre>distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
   && curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add - \
   && curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list</pre>

Note:  To get access to experimental features such as CUDA on WSL or the new MIG capability on A100, you may want to add the experimental branch to the repository listing:

 curl -s -L https://nvidia.github.io/nvidia-container-runtime/experimental/$distribution/nvidia-container-runtime.list | sudo tee /etc/apt/sources.list.d/nvidia-container-runtime.list

Install the nvidia-docker2 package (and dependencies) after updating the package listing:
 sudo apt-get update
 sudo apt-get install -y nvidia-docker2

== Finishing the install ==
Restart the Docker daemon to complete the installation after setting the default runtime:
 sudo systemctl restart docker

Test nvidia-smi with the latest official CUDA image
 sudo docker run --rm --gpus all nvidia/cuda:11.0-base nvidia-smi

Test the GPU performance using a simple NVIDIA GPU Cloud container with the CUDA nbody sample program
 docker run -it --rm --gpus all nvcr.io/nvidia/k8s/cuda-sample:nbody nbody -benchmark -fp64

= Reloading Repository Certificates =

Rather frequently, it seems, the NVIDIA folks invalidate their signing certificates for their repositories.  When that happens, you just need to delete the certificates and let the 'yum' command reload them on the next update:

 $(sed -n 's/releasever=//p' /etc/yum.conf)
 ${DIST:-$(. /etc/os-release; echo $VERSION_ID)}
 sudo rpm -e gpg-pubkey-f796ecb0
 sudo gpg --homedir /var/lib/yum/repos/$(uname -m)/$DIST/nvidia-container-runtime/gpgdir --delete-key f796ecb0
 sudo gpg --homedir /var/lib/yum/repos/$(uname -m)/$DIST/libnvidia-container/gpgdir --delete-key f796ecb0
 sudo gpg --homedir /var/lib/yum/repos/$(uname -m)/$DIST/nvidia-docker/gpgdir --delete-key f796ecb0
 sudo yum -y makecache
