Learn Docker from Scratch with Hands-On Demo

📦Docker is a popular containerization platform used to deploy applications in various environments.

🏭Docker architecture consists of Docker host, daemon, and client, along with the Docker registry for storing and distributing images.

📂Docker images are created using Dockerfiles, which contain instructions for building and configuring containers.

💻Docker client allows users to interact with the Docker daemon through API calls, using either CLI or a graphical user interface.

🚀Containerizing applications with Docker provides consistency, portability, and scalability across different platforms.

What is Docker?

—Docker is a containerization platform used to deploy applications as containers, which provide a lightweight and isolated runtime environment.

What are the key components of Docker?

—Docker consists of Docker host, Docker daemon, and Docker client, along with Docker registry for storing and sharing images.

How does Docker architecture work?

—Docker architecture involves the Docker daemon running on the Docker host, and the Docker client interacting with the daemon to manage containers and images.

How do you create Docker images?

—Docker images are created using Dockerfiles, which contain instructions for building and configuring the containers.

What are the advantages of containerizing applications with Docker?

—Containerizing applications with Docker provides consistency, portability, and scalability across different platforms, making it easier to deploy and manage applications.
