Docker
Docker is a platform for developing, shipping, and running applications in containers. Containers package an application with all its dependencies into a standardised unit, ensuring it runs the same way regardless of where it's deployed—developer laptop, test server, or production cloud. For non-technical readers, think of Docker containers as shipping containers for software. Just as shipping containers standardised global trade, Docker containers standardise software delivery, making applications portable and predictable.
Official WebsiteWhen to use Docker
Use Docker when you need consistent environments across development, testing, and production. It's essential for microservices architectures, CI/CD pipelines, and cloud-native applications. Docker simplifies dependency management and enables rapid, reliable deployments.
Why choose Docker?
Teams choose Docker for its portability, efficiency, and ecosystem. It eliminates "works on my machine" problems, speeds up onboarding, and integrates with orchestration platforms like Kubernetes. The Docker Hub registry provides access to thousands of pre-built images.
