What is Docker? Introduction to Docker for Beginners

🚀 Welcome to CodeOps Trek! 🎉

In this video, we take a deep dive into Docker and containerization, exploring how it has revolutionized software deployment by eliminating the limitations of traditional virtualization.

✅ Before Docker: The Evolution of Software Deployment

🔹 The Bare Metal Era: Applications were directly installed on physical servers, leading to inefficient hardware utilization and dependency conflicts.
🔹 The Virtualization Era: The introduction of Hypervisors (like VMware, VirtualBox) allowed running multiple Virtual Machines (VMs) on a single server, but VMs were heavyweight, resource-intensive, and required separate OS installations.
🔹 The Rise of Docker & Containers: Docker solved these issues by introducing lightweight containers that share the host OS kernel while providing an isolated environment for applications.

✅ What You’ll Learn in This Video?
🔹 What is Docker, and why is it needed?
🔹 What is a Hypervisor, and how does it work?
🔹 What are Virtual Machines (VMs), and how are they different from Containers?
🔹 How does Docker work compared to Virtual Machines?
🔹 What is a Docker Container, Image, and Docker Engine?
🔹 How do containers provide isolation without a separate OS?
🔹 Why is Docker faster and more efficient than traditional virtualization?
