The docker project offers higher-level tools, working together, which are built on top of some Linux kernel features. The goal is to help developers and system administrators port applications - with all of their dependencies conjointly - and get them running across systems and machines.
Docker achieves this by creating safe, LXC (i.e. Linux Containers) based environments for applications called Docker containers. These containers are created using docker images, which can be built either by executing commands manually or automatically through Dockerfiles.
