To run:

Install Docker, then build the container locally:

docker build -t <container-name>

(Use your own container name)

Then run the container from the folder that contains the app folder:

docker run -v ${PWD}/app:/app <container-name>

In the above call, -v means to bind a volume; the local app directory is bound to the container's app folder, so that any input/output files can be accessed locally even though the container is run in isolation.
