Containerization with Docker
Create Dockerfiles, build images, and run your Node.js application in containers for consistent environments.
Docker: Consistent Environments
Welcome to containerization with Docker! Docker helps package your application and its dependencies into a single unit called a container.
This ensures your app runs consistently across different environments, from your laptop to production servers.
Images vs. Containers
Think of a Docker Image as a blueprint or a template. It's a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries, and settings.
A Docker Container is a running instance of an image. You can have multiple containers running from the same image, each isolated from the others.
