无法在 ctr 容器中为 nvidia 配置运行时

编程问答 2022-05-22

问题描述

我试图在 ctr 的帮助下运行图像。要运行的容器取决于 nvidia 运行时。 我的 containerd 版本是 1.3，我也配置了 nvidia-container-runtime。我正在使用以下命令运行图像

sudo ctr-enc run -t --detach --rm --runtime io.containerd.runc.v1 --net-host --mount type=bind,src=$HOME/images/,dst=/home/shared/images,options=rbind:ro <image-name>

我的/etc/containerd/config.toml文件如下

我已按照 this 链接中的建议在默认配置的末尾添加了 privileged_without_host_devices = false 部分

正如您从 ctr-enc 命令中看到的，我试图将运行时指定为 "io.containerd.runc.v1"。 但是容器似乎没有与提供的位置绑定。该文件夹是在运行此容器时创建的，但文件夹内没有数据。 请让我知道我需要如何为 nvidia 配置运行时，以便此图像按预期工作。
