OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	#!/bin/bash

	# vars
	[ -z "$NUM_WORKERS" ] && NUM_WORKERS=3

	# init swarm (need for service command); if not created
	docker node ls 2> /dev/null \| grep "Leader"
	if [ $? -ne 0 ]; then
	docker swarm init > /dev/null 2>&1
	fi
