安装docker&nvidia-docker

Ubuntu18.04环境

安装docker

1. 下载安装包
   wget -qO- https://get.docker.com/ | sh

2. 使非root用户可以直接运行docker
   sudo usermod -aG docker luobu
   然后退出再重新登录。

3. 测试
   docker run hello-world

4. 卸载旧版本docker：
   sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt autoremove

安装nvidia-docker

主要参见官方教程nvidia-docker，更清楚。

# If you have nvidia-docker 1.0 installed: we need to remove it and all existing GPU containers
docker volume ls -q -f driver=nvidia-docker | xargs -r -I{} -n1 docker ps -q -a -f volume={} | xargs -r docker rm -f
sudo apt-get purge -y nvidia-docker

# Add the package repositories
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | \
  sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
  sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update

# Install nvidia-docker2 and reload the Docker daemon configuration
sudo apt-get install -y nvidia-docker2
sudo pkill -SIGHUP dockerd

# Test nvidia-smi with the latest official CUDA image
docker run --runtime=nvidia --rm nvidia/cuda:9.0-base nvidia-smi
