Docker is a powerful open-source platform designed to streamline the development, deployment, and running of applications inside containers. It provides a lightweight, consistent environment for developers to build, test, and deploy applications across different systems, ensuring portability and scalability. Docker simplifies the deployment process by encapsulating applications and their dependencies into containers, making it easier to move and run them in different environments, from local machines to the cloud.

Features of Docker:

• Containerization: Allows applications to run in isolated containers, ensuring consistent environments across different machines and systems.
• Easy Deployment: Provides an easy-to-use command-line interface and Docker Compose for managing multi-container applications.
• Portability: Docker containers can run on any system that supports Docker, including Linux, macOS, and Windows, enabling cross-platform portability.
• Scalability: Supports easy scaling of applications by replicating containers and managing clusters using Docker Swarm or Kubernetes.
• Integration with CI/CD Pipelines: Seamlessly integrates with continuous integration and continuous deployment (CI/CD) tools, improving development and deployment workflows.
• Vibrant Ecosystem: Docker Hub provides a rich repository of pre-built images for various applications, making it easy to get started with popular software.

To check the version of Docker: docker --version
