3. What is Docker?
Docker is “an open source project to pack,
ship and run any application as a lightweight
container.” The idea is to provide a
comprehensive abstraction layer that allows
developers to “containerize” or “package” any
application and have it run on any
infrastructure.
“Build, Ship and Run Any App, Anywhere”

4. Docker Containers ?
Docker containers are similar to shipping containers:
The container is always the same, regardless of the
contents and thus fits on all trucks, cranes, ships.

5. What is Docker Engine?
■ Open Source Project written in Go
■ Released March, 2013
■ Provides the Docker Container - Repeatable Runtimes,
Sandboxing, Network, and Storage
■ Linux and (soon) Windows CLI tools for Developers
■ Local and Remote REST API for further integration
■ Low level API for Runtime, Storage, and Network
extension
