What is docker and containerization

Question

Accepted Answer

Docker is a platform for developing, shipping, and running applications in containers, which are lightweight, portable, and isolated environments.

Docker is a tool that allows you to package an application and its dependencies into a standardized unit called a container.
Containers are isolated environments that contain everything needed to run the application, including code, runtime, system tools, libraries, and settings.
Containerization helps in ensuring consistency across different environments, making it easier to deploy and scale applications.
Docker enables developers to build, ship, and run applications on any platform without worrying about differences in operating systems or dependencies.
Example: Running a web application in a Docker container allows developers to easily deploy the same application on different servers or cloud platforms.
