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?

I use Docker to keep my development machine clean. For example: https://github.com/ChanderG/H99. For playing with different technologies, I love the ease and organization that Docker offers.

tldr; Get sucked in by image creation, stay for the API.

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.

I think is nice for building PaaS like backends AKA microservices and also to automate large deployments when you need isolated small machines.

Containers as a concept are nice, but I'm not sure if Docker specifically is the best implementation yet.

Its modern static linking.
