Have no idea why Docker showing this (un-friendly) error message.
In fact, it caused by the bash script file created in Windows having different line ending and cannot run properly in Linux container.

standard_init_linux.go:190: exec user process caused "no such file or directory"

Here is the fix using Notepad++.
First show the linefeed symbol.

You will see this.

Convert the linefeed from Windows to Unix.

You will get this, and save it 🙂
