As part of an effort to make the scikit-image examples gallery interactive, I would like to build a web service that receives a Python code snippet, executes it, and provides me with the generated output image.
For safety, the Python instances launched should be sandboxed and resource controlled, so I was thinking of using LXC containers.
Is this a good way to approach the problem? If so, what is the recommended way of launching one Python VM per request?
Stefan, perhaps "Docker" could be of use? I get the impression that you could constrain the VM that the application is run in -- an example web service:
http://docs.docker.io/en/latest/examples/python_web_app/
You could try running the application on Digital Ocean, like so:
