Docker vs Flocker: What are the differences?

What is Docker? Enterprise Container Platform for High-Velocity Innovation. The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere.

What is Flocker? Run your databases in Docker and make them as portable as the rest of your app. Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.

Docker and Flocker are primarily classified as "Virtual Machine Platforms & Containers" and "Container" tools respectively.

"Rapid integration and build up" is the top reason why over 816 developers like Docker, while over 3 developers mention "Open-Source" as the leading cause for choosing Flocker.

Docker and Flocker are both open source tools. It seems that Docker with 54K GitHub stars and 15.6K forks on GitHub has more adoption than Flocker with 3.19K GitHub stars and 287 GitHub forks.

Chose

over
DockerDocker

lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.
