A container registry is a resource that allows you to store and catalog container images, which serve as ‘templates’ for container workloads that get deployed in cloud environments. Container images can be ‘pushed’ and ‘pulled’ to and from registries as part of DevOps workflows or continuous integration/continuous deployment (CI/CD) pipelines.
Container registries are a key component of DevOps pipelines, useful resources for container orchestration engines such as Kubernetes, and a vital endpoint for container-based development. They help to centralize the management of container images and establish a single source of truth for container workloads.
