Docker
Docker is an open-source platform that simplifies the process of developing, shipping, and running applications by using containerization technology. Containers are lightweight, portable environments that include everything an application needs to run—such as code, runtime, libraries, and system tools—ensuring consistency across different computing environments. Unlike traditional virtual machines, Docker containers share the host operating system’s kernel, making them faster, more efficient, and easier to deploy. Developers use Docker to eliminate compatibility issues between development and production environments, streamline workflows, and enhance scalability. With tools like Docker Engine, Docker Compose, and Docker Hub, users can build, manage, and distribute containerized applications efficiently. Overall, Docker has become an essential tool in modern software development, enabling continuous integration, continuous deployment (CI/CD), and microservices-based architectures.
