local file extractor configuration yaml environment variable setup

Hope this documentation here will help you. 

In short:

You have to specify the environment variables in the config.yaml file.

cognite:

   secret: ${CLIENT_SECRET}

Then you need some way to populate the environment variable with the correct value. 

Some (most) of the extractors support adding an .env file in the same directory as where you’re running the extractor binary from. Other approaches depend on how (and on what platform) you start/run the extractor. 

IIRC, we recently updated the extractors to prevent traversal searches for .env files, so the location of the .env file will matter :)

Thank you for the clarification, so in general, does the Local file extractor support the .env? of course I put the .env file in the same directory as the yaml configuration file.
