Ask HN: What do you really think about docker?
Lots of push and articles about how docker is awesome, wanted to see what the larger community thought about using docker?
The documentation could be better. Getting my brain around what a Docker commit actually is and when the cache breaks for a RUN command vs a COPY command took some digging.
They are definitely catering to the "up and running" crowd.
The idea of combining image creation with container deployment and making the CLI as "sugar-ey" and "user-friendly" as possible is mostly marketing fluff designed to make containers easy to swallow for the masses.
However, the API IS powerful. Combined with tools like CoreOS and Kubernetes, or some in-house custom built tools and Docker is a pretty spicy piece of technology that is definitely worth it.
