如何在Docker容器中运行OpenCL + OpenGL？ [英] How to run OpenCL + OpenGL inside a Docker container?

问题描述

目标是在docker容器中运行OpenCL / OpenGL（互操作）应用程序。但是我还没有成功。

The aim is to run an OpenCL/OpenGL (interop) app inside a docker container. But I have not been successful yet.

我有一台装有NVidia显卡的笔记本电脑，所以我想利用NVidia Dockerfiles [1,2

I have laptop with an NVidia graphics card so I thought leveraging on NVidia Dockerfiles [1,2] would be a good starting point.

以下Dockerfile：

The following Dockerfile:

# Dockerfile to run OpenGL app
FROM nvidia/opengl:1.0-glvnd-runtime-ubuntu16.04
ENV NVIDIA_DRIVER_CAPABILITIES ${NVIDIA_DRIVER_CAPABILITIES},display
RUN apt-get update && apt-get install -y --no-install-recommends \
        mesa-utils && \
    rm -rf /var/lib/apt/lists/*

效果很好，我能够运行 glxgears 。

works quite well, and I was able to run glxgears.

在自己的容器上运行OpenCL也没什么大不了的：

Running OpenCL on its own container was no big deal either:

# Dockerfile to run OpenCL app
FROM nvidia/opengl:1.0-glvnd-runtime-ubuntu16.04
RUN apt-get update && apt-get install -y --no-install-recommends \
        ocl-icd-libopencl1 \
        clinfo && \
    rm -rf /var/lib/apt/lists/*
RUN mkdir -p /etc/OpenCL/vendors && \
    echo "libnvidia-opencl.so.1" > /etc/OpenCL/vendors/nvidia.icd
ENV NVIDIA_VISIBLE_DEVICES all
ENV NVIDIA_DRIVER_CAPABILITIES compute,utility

并且 clinfo 成功显示了有关我的设备的信息。

and clinfo successfully shows information about my device.

最后，我尝试用OpenGL和OpenCL驱动程序创建一个容器：

Finally here's my attempt at creating a container with both OpenGL and OpenCL drivers:

# Dockerfile mixing OpenGL and OpenCL
FROM nvidia/opengl:1.0-glvnd-runtime-ubuntu16.04
ENV NVIDIA_DRIVER_CAPABILITIES ${NVIDIA_DRIVER_CAPABILITIES},display
RUN apt-get update && apt-get install -y --no-install-recommends \
        mesa-utils \
        ocl-icd-libopencl1 \
        clinfo && \
    rm -rf /var/lib/apt/lists/*
RUN mkdir -p /etc/OpenCL/vendors && \
    echo "libnvidia-opencl.so.1" > /etc/OpenCL/vendors/nvidia.icd
ENV NVIDIA_VISIBLE_DEVICES all
ENV NVIDIA_DRIVER_CAPABILITIES compute,utility

现在，尽管 clinfo 仍会打印OpenCL设备信息，但 glxgears 却失败，并出现以下错误：

And now, although clinfo still prints OpenCL device information, glxgears on the other hand fails with the following error:

Error: couldn't get an RGB, Double-buffered visual 

任何想法如何使它起作用？

Any idea how to make this work? Thanks in advance.

推荐答案

ENV NVIDIA_DRIVER_CAPABILITIES compute,utility

您忘记了功能显示。
