Which of the following statements about container registries is true?

1. They only hold public images

2. They serve as the central repository for container images

3. They do not allow for image versioning

4. They are only used during the deployment phase

The correct answer is: They serve as the central repository for container images

Container registries function as central repositories for container images, making them crucial in the workflow of container-based application development and deployment. They store both public and private images, which can be accessed and utilized by developers and applications across various environments. This capability supports the entire lifecycle of an image, from development to testing and production, rather than being limited to just the deployment phase. Additionally, container registries support image versioning, allowing users to manage different versions of the same image seamlessly. This is important for ensuring reproducibility and consistency in application deployments. The understanding of container registries as central repositories highlights their role in facilitating collaboration, security, and resource management within DevOps practices, emphasizing why this statement is accurate and reflects the essential functions of a container registry in modern software development.
