tldr; Get sucked in by image creation, stay for the API.<p>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.<p>They are definitely catering to the &quot;up and running&quot; crowd.<p>The idea of combining image creation with container deployment and making the CLI as &quot;sugar-ey&quot; and &quot;user-friendly&quot; as possible is mostly marketing fluff designed to make containers easy to swallow for the masses.<p>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.
