Docker is a platform for developing, shipping, and running applications in isolated environments called containers. Think of containers as lightweight, standalone, executable packages of software that include everything needed to run an application: code, runtime, system tools, system libraries, and settings. Key Concepts of Docker: Containers: Isolated, lightweight, and portable environments that package an application and its dependencies. Unlike virtual machines (VMs), containers share the host OS kernel, making them much more efficient in terms of resource usage and startup time. Images: Read-only templates that are used to create containers...

Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud. Source: What is Docker Cheatsheets by Docker EE is on the same code base as Docker...
