Dockers Overview

Docker is an open-source project that automates the deployment of applications inside software containers

Feature of Dockers

Package your application

• Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server.
• It can be target to any OS or environment
• Additional layer of abstraction and automation of operating-system-level virtualization on Windows and Linux.

Speed

• Containers running on a single machine share the same operating system kernel; they start instantly and use less RAM. Images are constructed from layered filesystems and share common files, making disk usage and image downloads much more efficient.

Open

• Docker containers are based on open standards, enabling containers to run on all major Linux distributions and on Microsoft Windows -- and on top of any infrastructure.

Secure

• Containers isolate applications from one another and the underlying infrastructure, while providing an added layer of protection for the application.
