On topic, I've been spending some time looking at Docker this morning because there seems to be a lot of buzz around it. I am winding this exploration down for the moment because I am discovering that for all the talk about how easy and fast Docker makes things, the list of what you can do with it today amounts to:
- mysql, apache and sshd Wordpress stack
- nginx, php and Wordpress
So, right now aside from the dubious differentiator of being able to spin up an SSD-hosted WordPress instance in 78 seconds, Docker doesn't seem to be very compelling. I will certainly keep an eye on it though.
As for your docker thoughts - I'll let the docker team address those more fully.
