Hmm, your parameters seems to be setup correct, at least as far as I can see.
Hopefully someone else can chime in on the topic. I am slightly unaware what the cause can be.
My final suggestions would be:
- Check the version of the engine that you are using in the container, as well as the version of the Vulkan SDK that is installed.
- Check if the container has correct permissions to run the engine and the project and whether the environment variables are set correctly.
- Consider that the render offscreen and no sound parameters you passed in the boot parameter, could be causing the problem. You can try to remove these parameters and test again.
- You might want to consider using a pre-built image that has the engine and the dependencies already installed, or use a base image that includes the necessary dependencies, like the UnrealEngine/Runtime image from the Unreal Engine’s Docker hub page.
