Everywhere I've ever worked that had docker/vagrant, the devops guy has promised me easy, one command environments, and not once has it worked. I've seen the product they are selling, I've watched a docker command build me a multi-part infrastructure, automatically source databases and assets from afar, and do it all quickly. But then it failed the second time I tried it. I've not found it to be a reliable tool at all.
