Docker

Docker is a platform designed to simplify the development, shipment, and deployment of applications by using containerization. By packaging an application and its dependencies into a standardized unit called a container, Docker ensures that the software will run consistently across different computing environments. This approach eliminates the common problem of “it works on my machine” by providing an isolated environment that encapsulates everything needed for the application to run. Docker containers are lightweight, portable, and can be easily scaled, making them ideal for microservices architecture and continuous integration/continuous deployment (CI/CD) pipelines. The platform’s efficiency and flexibility have made it a cornerstone technology in modern DevOps practices, greatly enhancing productivity and operational agility.
