Description

I currently try to make the .funcignore more deterministic by using the git-like antipattern to only include the files needed to deploy the function.

#.funcignore
# Ignore everything
*

!.funcignore
!function_app.py
!host.json
!requirements.txt

which results in:

# log output
1:09:17 PM func-example-02: Starting deployment...
1:09:17 PM func-example-02: Creating zip package...
1:09:17 PM func-example-02: Adding 0 files to zip package...
1:09:17 PM func-example-02: Zip package size: 22 B

Steps to reproduce

1. create .funcignore
2. deploy function
