PY-SPY alpine based image

Thank you very much for this! The repository describes how to use it.

I don't know how this thing works, but it works! (It's a pity that it is not included with the python)

Here is an example for a very special case.

docker run -it --rm --name test -v $(pwd):/src python:alpine python /src/script.py

Get process pid from host point of view

docker top test  # get PID and paste to command
docker run -it --rm --pid="host" --privileged -v /tmp/spy:/tmp/spy freeman1981/py-spy-alpine py-spy record -o /tmp/spy/profile.svg --pid <PID>

After waiting a while, press ctrl+c. Let's go look at the picture /tmp/spy/profile.svg and see what we expected - the function slow was executed the longest.
