I would like to know if there's a way to input multiple files to the environment variable SWAGGER_JSON variable in Docker that will generate something like a drop list in the UI or something.

For now I have something similar to this on my Dockerfile:

ENV SWAGGER_JSON "/docs/doc1.yaml"

And would like to know if there's a structure that maybe looks like:

ENV SWAGGER_JSON "['/docs/doc1.yaml','/docs/doc2.yaml']"
