can anyone help me to fix it .

Answer: 
Docker images are an [open and documented](https://github.com/opencontainers/image-spec) "application packaging" format. There are countless ways to inspect the image contents, including all of the python source code shipped inside of them.

Running applications inside of a container provides isolation from the application escaping the container to access the host. They do not protect you from users on the host inspecting what is occurring inside of the container.
I know that´s been more than 3 years, but... looking for the same kind of solution I think that including compiled python code -not your source code- inside the container would be a challenging trial for someone trying to access your valuable source code.

If you run `pyinstaller --onefile yourscript.py` you will get a compiled single file that can be run as an executable. I have only tested it in Raspberry, but as far as I know it´s the same for, say, Windows.

Of course anything can be reverse engineered, but hopefully it won´t be worth the effort to the regular end user.
