Скачать или смотреть Deploying a Node.js Application with Docker || PART I

Docker is a platform that allows developers to easily create, deploy, and run applications in containers. Containers are lightweight, portable, and self-sufficient, which means they can run consistently across different environments.
A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.
Docker uses a containerization approach to virtualization, which is different from traditional virtualization. Traditional virtualization involves creating a virtual machine that runs on top of a host operating system, while containerization involves running multiple isolated containers on a single host operating system. This allows for more efficient use of system resources and better performance.
Docker provides a way to package an application with all of its dependencies into a single container, and then run that container on any machine that has Docker installed. This makes it easy to move the application between development, testing, and production environments.

CI/CD stands for Continuous Integration and Continuous Deployment. It is a software development practice that involves automatically building, testing, and deploying code changes as soon as they are committed to a code repository.
Continuous Integration (CI) is the practice of automatically building and testing code changes as soon as they are committed to the code repository. This helps to catch and fix any issues early in the development process, before they can become harder and more expensive to fix.
