Course Details
Docker revolutionized the way we build, ship, and run applications by introducing containers as a lightweight, portable, and efficient way to package software. Whether you're a developer, DevOps engineer, or IT administrator, Docker simplifies workflows and enables consistent environments from development to production.
Docker
Docker is an open-source platform that enables developers to automate the deployment, scaling, and management of applications using containers. Containers are lightweight, portable, and self-sufficient units that package an application and all its dependencies, so it runs reliably in any environment. In simpler terms: Docker helps you build once and run anywhere—locally, in testing, or in production.

Why Use Docker?
Consistency: "It works on my machine" issues disappear because the app runs the same everywhere.
Isolation: Applications run in their own container without affecting each other.
Portability: Containers can be easily moved between environments.
Efficiency: Containers share the host OS kernel, using fewer resources than virtual machines.
Docker Architecture
Docker Engine:The core client-server technology that runs and manages containers.
Docker Images: Images include the application code, runtime, libraries, environment variables, and configuration files.
Docker Containers: Containers are isolated from each other and the host machine.
Docker Registries: Storage and distribution system for Docker images.
How Docker Works
You write a Dockerfile to define how your app should be packaged.
You use the docker build command to create a Docker image.
You run the image with docker run, which starts a container.
The container runs the app inside a clean and consistent environment.
Use Cases for Docker
Microservices architecture: Each service runs in its own container.
Dev/test environments: Easily replicate production setup locally.
CI/CD pipelines: Build and test code inside containers.
Cloud deployments: Containers can be deployed across AWS, Azure, GCP.
Legacy app modernization: Wrap old apps in containers for easier deployment.
Real-World Examples
Netflix uses Docker for efficient development and deployment of microservices.
Spotify containers for running services in isolated environments.
Groupon, PayPal, and many other companies use Docker in production to streamline CI/CD pipelines.
