Reading some of the other comments in this thread, I think I'm getting a better idea of why this guy is suggesting that SSH in Docker could complicate things, especially when you are scaling to a large number of servers, but what I still don't quite understand his argument about security updates. Is that in any way SSH specific, beyond the fact that SSH is powerful and it's critical to be up-to-date on powerful things? If it's a problem to update SSH, then it should also be a problem to update whatever else you have in your Docker container. I guess there's some argument to be made that if you're running a single-purpose Docker container, the updates to whatever service it's running won't sync up with the updates to SSH, so you may drastically increase the number of times you'll have to package the image, but that's just a general argument in favor of single-purpose containers, not anything specific to SSH like the key management issue.
