Deploying a Node.js Application with Docker PART II |Git SSH Key

Docker is a platform for developing, shipping, and running applications in containers. Containers are lightweight, portable, and self-sufficient, which makes them ideal for running applications in different environments.

When using Docker with Node.js, you can package your Node.js application and its dependencies into a container. This ensures that your application runs consistently across different environments and eliminates the need to handle differences in the underlying infrastructure.

To run a Node.js application in a Docker container, you'll need to first create a Dockerfile that defines the environment and dependencies for your application. The Dockerfile typically starts with a base image, such as the official Node.js image, and then adds your application code and any necessary dependencies.

Git is a version control system for software development. It allows developers to track changes to their code, collaborate with others, and manage different versions of their codebase.

SSH (Secure Shell) is a network protocol that allows secure remote login and other network services to operate securely over an insecure network. It is often used to log into a remote machine and execute commands, but it can also be used to securely transfer files.
