what is container

A container is a lightweight, stand-alone, and executable software package that includes everything needed to run an application: the application code, runtime, system tools, libraries, and settings. Containers provide a way to package and distribute applications, making them easy to deploy and run consistently across different environments.

Containers are often used in the development and deployment of software applications, particularly in the context of microservices and cloud computing. They enable developers to create and test applications in a contained environment that is isolated from the rest of the system, and then easily deploy those applications in any environment that can run the container runtime. This allows for greater portability and consistency of the application across different environments, as well as easier and faster deployment.

There are several technologies and platforms available for creating and running containers, including Docker, Kubernetes, and OpenShift. These platforms provide tools for building, deploying, and managing containers at scale, making it easier to deploy and run applications in a distributed and cloud-based environment.
