Python I/O redirection with Docker example

Toy project experimenting how to use a Python app inside a Docker container to stream commands via STDIN and receive responses via STDOUT just like you would do with a local Python app.

This might help in deciding how to invoke apps embedded with Docker.

Building the Docker image

docker build -t mypy .

Invoking it

$ cat input.json | docker run --rm -i mypy
