I don't think it was even that. It was massive marketing and hype which drove docker adoption. The engineering concerns and the user experience were both negatives because they actually added a considerable cost and friction to the experience. I will obviously need to back that comment up but fundamentally the security posture of docker (and most package repositories) is scary and the ability to debug containers and manage them adds considerable complexity. Not to mention the half baked me-too offerings that circle around the product (windows containers anyone?) The repeatability argument is dead when you have no idea what or who the hell your base layers came from. What it did was build a new market for ancillary products which is why the marketing was accelerated. It made money. Quickly.
