Kubernetes or Docker are often compared, but they serve different purposes in the containerization landscape. Docker is a containerization platform that enables developers to create, package, and run applications in containers, ensuring consistency across different environments. It simplifies the development workflow and promotes application portability.

On the other hand, Kubernetes is a container orchestration system that automates the deployment, scaling, and management of containerized applications. It provides advanced features like load balancing, auto-scaling, and self-healing capabilities, making it ideal for orchestrating complex, multi-container deployments in production environments.

In summary, Docker is the tool for creating containers, while Kubernetes is the tool for managing and scaling those containers in a production-ready setup.
