Image Registry
An image registry is a centralized storage and distribution system for container images, such as Docker images, used in containerized applications. It allows developers to push, pull, and manage container images, enabling consistent deployment across different environments. Registries often include features like versioning, access control, and vulnerability scanning to support DevOps workflows.
Developers should learn and use image registries when working with containerized applications, as they are essential for storing and sharing container images across development, testing, and production environments. This is critical in CI/CD pipelines for automating deployments, ensuring image consistency, and facilitating collaboration in teams using technologies like Docker and Kubernetes.
