Almost Everything about Docker

Docker, a revolutionary platform that has transformed the landscape of software development and deployment, is nothing short of a technological marvel. In this comprehensive guide, we embark on a journey to explore almost everything about Docker. From the fundamental concepts to advanced techniques, we will unravel the intricacies of Docker, providing you with a deep understanding of its functionalities, use cases, and the power it brings to the world of containerization.

I. Introduction to Docker

A. What is Docker?

Docker is an open-source platform that automates the deployment of applications inside lightweight, portable containers. These containers encapsulate everything needed to run an application, including the code, runtime, libraries, and system tools. Docker enables consistent and reproducible deployments across various environments, fostering a seamless transition from development to testing and production.

B. Why Docker?

1. Isolation: Containers provide a level of isolation, ensuring that applications run consistently regardless of the environment.
2. Portability: Docker containers can run on any machine that supports Docker, eliminating the “it works on my machine” problem.
3. Efficiency: Containers…
