This Gist is a sandbox for learning how to use the https://github.com/p1c2u/openapi-core Python library.

1. Clone this repo
2. Build the Docker image
3. Run python openapicore.py

Build and run the script in a container:

docker build . -t openapi-core-test
docker run --rm -it openapi-core-test python openapicore.py 

The version of openapi-core is 0.18.1:

$ docker run --rm -it openapi-core-test bash
