使用 cuda 运行时构建 docker 镜像

Question

我正在构建一个图像，同时需要测试 GPU 可用性。GPU 容器运行良好：

$ docker run --rm --runtime=nvidia nvidia/cuda:9.2-devel-ubuntu18.04 nvidia-smi

但使用 GPU 构建时失败：

$ cat Dockerfile
FROM nvidia/cuda:9.2-devel-ubuntu18.04

RUN nvidia-smi
# RUN build something
# RUN tests require GPU

$ docker build .
Sending build context to Docker daemon  2.048kB
Step 1/2 : FROM nvidia/cuda:9.2-devel-ubuntu18.04
 ---> cdf6d16df818
Step 2/2 : RUN nvidia-smi
 ---> Running in 88f12f9dd7a5
/bin/sh: 1: nvidia-smi: not found
The command '/bin/sh -c nvidia-smi' returned a non-zero code: 127

我是码头工人的新手，但我认为我们在构建图像时需要进行健全性检查。那么如何使用 cuda 运行时构建 docker 镜像呢？

Answer 1

配置 docker daemon--default-runtime=nvidia解决了这个问题。
