Cleanup and reset docker on Jenkins workers / slaves

	#!/bin/bash
	# This script should be located on each Jenkins slave, and the jenkins user should have permission to run it with sudo

	# Attempts to cleanly stop and remove all containers, volumes and images.
	docker ps -q \| xargs --no-run-if-empty docker stop
	docker ps -q -a \| xargs --no-run-if-empty docker rm --force --volumes
	docker volume ls -q \| xargs --no-run-if-empty docker volume rm
	docker images -a -q \| xargs --no-run-if-empty docker rmi -f

	# Stops the docker service, unmounts all docker-related mounts, removes the entire docker directory, and starts docker again.

Project Euler problems

	--Problem 1

	{-
	If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9.
	The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
