Docker is an
open-source program that enables a
Linux application and its dependencies to be packaged as a container.
Container-based virtualization isolates applications from each other on a shared operating system (
OS). This approach standardizes
application program delivery, allowing
apps to run in any Linux environment, whether physical or virtual. Because they share the same operating system, containers are
portable among different Linux
distributions and are significantly smaller than virtual machine (
VM) images.
Docker competes with proprietary application containers such as the
VMware vApp and infrastructure abstraction tools like
Chef.
Solomon Hykes, CTO and founder of dotCloud, has posted a video tutorial for Docker.
