xyliucd/nxnode

1. 镜像运行脚本

docker run -itd --restart=on-failure \
    --name nx-shine \
    --cap-add=SYS_PTRACE \
    --gpus all  \
    -e DISPLAY=unix:0 \
    -v /tmp/.X11-unix:/tmp/.X11-unix:rw \
    -p 14000:4000  \
    xyliucd/nxnode:20.04

2. 构建镜像方法

构建脚本docker_build.sh：

#!/bin/bash

UBUNTU_VERSION="20.04"
CUDA_VERSION="11.2.1"
echo "ubuntu version:${UBUNTU_VERSION},cuda version:${CUDA_VERSION}"

BASE_IMAGE=nvidia/cudagl:${CUDA_VERSION}-base-ubuntu${UBUNTU_VERSION}
echo ${BASE_IMAGE}

docker build nxnode --file nxnode/20.04/Dockerfile \
             --build-arg BASE_IMAGE=${BASE_IMAGE} \
             --tag xyliucd/nxnode:20.04
if [[ $? != 0 ]]; then
    echo "Failed to build docker image 'xyliucd/nxnode:20.04'"
    exit -3
fi

exit 0

在nxnode目录下有以下文件和目录：

nxnode/
├── 20.04
│   └── Dockerfile
└── docker_config
    └── startup.sh

2 directories, 2 files

其中Dockerfile内容为：

ARG BASE_IMAGE=nvidia/cudagl:11.2.1-base-ubuntu20.04
