You can read more about reasons to use docker in a blogpost that I've recently wrote for my company.

But wait, there is more. This Thursday I gave a talk "Introduction to Docker" in Warsaw hackerspace! Here are the slides (thanks flickr for all the cat pictures on Creative Commons license):

Talks at Warsaw Hackerspace are really great. I love that there are really skilled people there, willing to get involved into discussion and ask important questions.
