Rahul Kumar Srijan Technologies Pvt Ltd, New Delhi, India Docker allows you to package your application with all of its dependencies into a standardized unit called container. Your application, for example, Drupal website, has dependencies, such as a web server (Nginx/Apache2) and a database (MySQL/MariaDB/PostgreSQL). And usually, when you want to deploy a new copy of your website, you install these dependencies manually via OS packaging system, such as apt-get or yum, then you configure them, install extensions, etc, which is not really a great experience. With Docker, you package your application into containers and then you can run these containers on almost any host. You can run it on your laptop, on a production server, inside your personal VPS or even inside of Vagrant.
