To make a clarification, I was not calling Docker hype, nor specifically remarking on any particular item. I use docker religiously. I even use dokku for about 30+ toy projects.
My remark was to highlight that buzzwords are often used for "me-too" ankle-deep conversations/articles. Whether someone calls it Devops, or Systems Engineering, makes no difference to me. However, I favor pragmatic conversations about the topic, rather than buzzword bingo.
Examples include: "MongoDB sucks.", "Everyone should use Docker", and "What? You mean you're not using Kubernetes for your CRUD app?"
Basically, blanket statements that accomplish nothing more than to send social signals.
