docker - 无法通过 Docker 驱动程序在 Minikube 上使用 GPU

Question

目标:

我正在尝试在使用默认 Docker 驱动程序的 Minikube 集群上使用 Nvidia GPU 功能。

问题:

我可以使用 nvidia-docker与默认 docker上下文，但是当切换到 minikube docker-env 时我收到以下错误:

$ docker run --gpus all nvidia/cuda:10.0-base nvidia-smi
docker: Error response from daemon: could not select device driver "" with capabilities: [[gpu]].
ERRO[0000] error waiting for container: context canceled

环境:

Ubuntu 18.04

Minikube v1.10.0

Docker 版本:

附加信息:

集群是通过以下方式创建的:

minikube start --cpus 3 --memory 8G

以下 minikube插件目前已启用:

这是 minikube 之外的一个工作示例语境:

Answer 1

这是一个社区维基答案。如果需要，请随意编辑和扩展它。

Minikube 的 docker 驱动程序不正式支持 Nvidia GPU。这为您提供了两种可能的选择:

尝试使用 NVIDIA Container Toolkit和 NVIDIA device plugin .这是一种解决方法，在您的用例中可能不是最佳解决方案。

使用 KVM2 driver或 None driver .这两个得到官方支持和记录。

我希望它有帮助。
