This introduction provides a gentle entry into the concept, ensuring clarity and context for the reader before discussing the specific Docker components.

These components that come together to help to create, manage, and run containers seamlessly.

Here are the main Docker components :-

1. Docker Daemon / Server / Engine — It is the heart of the docker and it runs on the host OS. It is responsible for running containers to manage docker service.
2. Docker Client — The Docker Client is a tool that allows you to interact with the Docker Engine. It’s the command-line interface (CLI) you use to send commands to Docker, like building images, running containers, or managing Docker resources. It acts as the user interface to communicate with Docker and perform tasks.
3. Docker Host — The physical or virtual machine that has Docker installed and runs containers. It acts as the environment where Docker can manage and execute containers.
4. Docker Images — These are like blueprints or recipes for your app. They contain everything your app needs to run, like the software and settings. When you want to start an app, you use an image to create a container.
5. Docker Containers — These are the actual running versions of your images. Imagine them as lightweight, self-contained “boxes” where your app runs, with everything it needs packed inside. They’re easy to start, stop, and move around.
6. Docker Compose — If you need more than one container for your app (like a web server and a database), Docker Compose helps you manage them all together. It lets you define and run multiple containers with a single command, making life easier.
7. Docker Hub — This is like a giant library or store where you can find, share, and store Docker images. You can download ready-to-use images or upload your own to share with others.
