Docker: ERROR: Copybara config file filename should be 'copy.bara.sky' but it is 'something.else.sky'

In README.md

A few environment variables exist to allow you to change how you run copybara:

• COPYBARA_CONFIG=copy.bara.sky
  allows you to specify a path to a config file, defaults to root copy.bara.sky

I tried running it:

docker run \
       -e COPYBARA_CONFIG='something.else.sky' \
       -e COPYBARA_WORKFLOW='master' \
       -v "$(pwd)":/usr/src/app \
       -it copybara copybara

However, when I specific a config other than copy.bara.sky the error; "Copybara config file filename should be 'copy.bara.sky' but it is 'something.else.sky'" will be raised.

This is expected. Copybara requires that the main config file is called "copy.bara.sky". The path can change, but not the name.
