Hello we are developing opengl applications inside docker on Pegasus machine using offscreen rendering. However so far we can only access the mesa opengl software device, the two GPUs are not accessible. I tried a small test program which works fine on the host but not in the docker.  
Here is the output from the host:

```auto
Detected 4 devices
Device 0 description: EGL_NV_device_cuda EGL_EXT_device_drm
Device 1 description: EGL_NV_device_cuda EGL_EXT_device_drm
Device 2 description: EGL_EXT_device_drm
Device 3 description: EGL_MESA_device_software

```

Here is the output inside the docker

```auto
Detected 2 devices
Device 0 description: EGL_EXT_device_drm
Device 1 description: EGL_MESA_device_software

```

The simple test program:

```auto
 #include <EGL/egl.h>
#include <EGL/eglext.h>
#include <iostream>

  static const EGLint configAttribs[] = {
          EGL_SURFACE_TYPE, EGL_PBUFFER_BIT,
          EGL_BLUE_SIZE, 8,
          EGL_GREEN_SIZE, 8,
          EGL_RED_SIZE, 8,
          EGL_DEPTH_SIZE, 8,
          EGL_RENDERABLE_TYPE, EGL_OPENGL_BIT,
          EGL_NONE
  };

  static const int pbufferWidth = 9;
  static const int pbufferHeight = 9;

  static const EGLint pbufferAttribs[] = {
        EGL_WIDTH, pbufferWidth,
        EGL_HEIGHT, pbufferHeight,
        EGL_NONE,
  };

int main(int argc, char *argv[])
{
  // 1. Initialize EGL

    static const int MAX_DEVICES = 20;
    EGLDeviceEXT eglDevs[MAX_DEVICES];
    EGLint numDevices;

    PFNEGLQUERYDEVICESEXTPROC eglQueryDevicesEXT =
        (PFNEGLQUERYDEVICESEXTPROC)eglGetProcAddress("eglQueryDevicesEXT");

    eglQueryDevicesEXT(MAX_DEVICES, eglDevs, &numDevices);

    //MW_INFO("Detected {} devices\n", numDevices);
    std::cout<<"Detected "<<numDevices<<" devices"<<std::endl;
    PFNEGLQUERYDEVICESTRINGEXTPROC eglQueryDeviceStringEXT =
        (PFNEGLQUERYDEVICESTRINGEXTPROC)eglGetProcAddress("eglQueryDeviceStringEXT");
    for(int i=0;i<numDevices;i++){
    const char *attr = eglQueryDeviceStringEXT(eglDevs[i], EGL_EXTENSIONS);
    //MW_INFO("Device {} description: {}",i, attr);
    std::cout<<"Device "<<i<<" description: "<<attr<<std::endl;
    }
  EGLDisplay eglDpy = eglGetDisplay(EGL_DEFAULT_DISPLAY);

  EGLint major=0, minor=0;

  eglInitialize(eglDpy, &major, &minor);
  std::cout<<"version="<<major<<"."<<minor<<std::endl;
  // 2. Select an appropriate configuration
  EGLint numConfigs;
  EGLConfig eglCfg;

  eglChooseConfig(eglDpy, configAttribs, &eglCfg, 1, &numConfigs);

  // 3. Create a surface
  EGLSurface eglSurf = eglCreatePbufferSurface(eglDpy, eglCfg,
                                               pbufferAttribs);

  // 4. Bind the API
  eglBindAPI(EGL_OPENGL_API);

  // 5. Create a context and make it current
  EGLContext eglCtx = eglCreateContext(eglDpy, eglCfg, EGL_NO_CONTEXT,
                                       NULL);
  std::cout<<"eglCtx="<<eglCtx<<std::endl;
  eglMakeCurrent(eglDpy, eglSurf, eglSurf, eglCtx);

  // from now on use your OpenGL context

  // 6. Terminate EGL when finished
  eglTerminate(eglDpy);
  return 0;
}

```

I did a lot of research trying to import all the GPU devices into the docker while start the container, tried to use nvidia/cudagl et al, but I have no success. Please kindly give me some idea on this. Thanks

Are you asking about GPU support of target docker?

@VickNV Thank you for the reply. Yes, we want to use both cuda and opengl hardware acceleration, but seems inside the docker I cannot use opengl (only software implementation is able to use)

target container with GPU isn’t supported. You need to wait for some release of DRIVE Orin.

@VickNV Thank you for the information. Just want to make sure the target container is the same as I referred. You mean that opengl is not supported in pegasus docker yet? But I see a few posts about this, and also nvidia container nvidia/cudagl, do you mean they are still not available on pegasus?

Thanks for your double-checking.

As mentioned in [NVIDIA DRIVE OS 5.2.6 Linux SDK Now Available | NVIDIA Technical Blog](https://developer.nvidia.com/blog/nvidia-drive-os-5-2-6-linux-sdk-now-available/), DRIVE OS 5.2.6 has Docker containers for only beta testing. But they don’t include any target container yet.

@VickNV I am not sure if I have access to the nvidia drive docker container. This is what I got from ngc:

@VickNV I am still not quite clear what the target container means. You mean the container on our target pegasus?  
Also I have a question, if Opengl works on the host, it shall also be able to work in the container provided the driver and libraries are installed in the container, Do I miss something here? Thanks

containers running on the target system aren’t supported yet.

Are you working on containers on host or target? Please check below for the details of the containers on host.

@VickNV Maybe I did not express myself clearly and I apologize for it. I am working on the target system using container. (directly on the pegausus system with a container built by ourselves). So I am having question, why it is not supported? we are using it for a long time already. What I mean the host is the pegasus system itself (in contrast to the docker, not talking about the host vs target using sdkmanager). Hope it clarifies the questions

Thanks for the clarification. The target container with GPU support is a planned feature from a DRIVE OS 6 release for DRIVE Orin.

Did you mean it used to work on your side and this is a regression in some release?

@Vicky, No, this is our first attempt to use opengl in the pegasus docker container (I am just not very sure about your statement: target container is not supported). The opengl works outside the container (on the target pegasus machine).  
What we are doing is very similar to this: [https://developer.nvidia.com/blog/egl-eye-opengl-visualization-without-x-server/](https://developer.nvidia.com/blog/egl-eye-opengl-visualization-without-x-server/)  
My question is why opengl works outside the container, but not in the container.

-rwxr-xr-x 1 root root 150408 Sep 20 06:24 libnvidia-container.so.1.5.1*

```

Are these files related to the issue? Thanks  
Update: I copied these nvidia files but issue remains the same. I guess the program is not calling nvidia’s lib

As I told you previously, it’s a feature of a DRIVE Orin release.  
I’m not sure how much I can help you here. May I know the importance to you?

@VickNV Thank you for your help. I just want to make sure you understand my question clearly. If it is not supported yet, that is fine and I just want to make sure the conclusion is solid. Sorry for the troubles.  
It is important since we are evaluating the nvidia pegasus as our autonomous driving platform.
