How to run programs in the sandbox and get their results on the site?

Question

Node.js

How can I run the program (let's say in Pascal), and then get what it outputs. Preferably something that works with node js. For example, this is on codeforces. Is there ready-made software for this (sandbox) or do you need a bicycle?

Answer 1

Docker
https://docs.docker.com/userguide/dockerizing/
to kill the container
$ sudo docker run ubuntu:14.04 /bin/echo 'Hello world'
Hello world
to kill the container after the task is completed, you need to add rm to the arguments.
