Following the official instructions, I met the following errors when executing the docker run ... command in Basic Usage of the readme, whenever I build the image myself or just pull the image from the Microsoft Container Registry.

/bin/sh: 1: /usr/local/startup_scripts/setup.py: Permission denied Error 126 executing from command. Exiting...

I reviewed the code of startup.py and Dockerfile. I think this is due to the lack of execute permission of setup.py. Then I chmod the permission, and the problem is solved.
