Makes system administration somewhat easier since the host OS can stay the same and docker containers change, while giving developers more control. I have total control of which version of packages is installed, which OS I'm using. I don't have to create a ticket, argue over the ask, and get approval just to change an web server timeout. It sort of usurps the sys admin role, though, which might be a negative. I can move my container anywhere that's running Docker and all packages are there inside of the container. If you spend a lot of time setting up new boxes, that's a plus. Before, I had to dump all packages, figure out which ones were missing, then install all of them, and the host OS had to be exactly the same. Now I know it's exactly the same, all the time, anywhere.

My only warning is that using anything but Ubuntu for your build host is going to take way too long and you're going to be waiting hours for it to complete if you don't have any layers cached.
