Docker Overview

docker

Docker is an open platform that allows developers to automate the deployment of applications inside lightweight, portable containers. This makes it easy to manage and scale applications across different environments.

What is a Container?

A container is a standard unit of software that packages code and all its dependencies, ensuring the application runs quickly and reliably from one computing environment to another.

  • Containers isolate the application environment.

  • Unlike VMs, containers share the host system’s OS kernel, making them lightweight.
