Hi, I created Docker. I have exactly 3 things to say: 1) Competition is always good. Lxc brought competition to openvz and vserver. Docker brought competition to lxc. And now tools like lxd, rocket and nspawn are bringing competition to Docker. In response Docker is forced to up its game and earn its right to be the dominant tool. This is a good thing. 2) "disappointed" doesn't even begin to describe how I feel about…
Ops (particularly in Enterprise) doesn't want batteries included by default. Principle #3 and #5 are incompatible IMO. Do one thing and do it well... Seems to me that post-Docker 1.2, the Docker team has taken Ops concerns much less seriously and is focused almost exclusively on iterating Dev-friendly features. Hope things change.
It feels to me like a lot of startups, and even smaller tech companies focus completely on developers. I seriously think some people think "DevOps" literally means Developers doing what Operations/Infrastructure people/teams do (or should do).
