title: How do I deal with security updates in Docker images?
body: <p>I'm interested in trying the <a href="https://github.com/docker-library/docs/tree/master/wordpress" rel="nofollow">wordpress</a> image for Docker. I think I understand the general concept. What am I supposed to do about security updated to something like PHP, or the Ubuntu image underneath? How do I keep the whole stack secure, while still keeping my blog intact? </p>
