A container registry is a storage and distribution system for container images. It allows developers to store, manage, and share container images, which are used to create and run containers in various environments.
Key features of a container registry include:
-
Image Storage: It provides a centralized location to store container images, making it easy to manage different versions and configurations.
-
Versioning: Container registries support tagging of images, allowing users to maintain multiple versions of an image (e.g.,
latest,v1.0, etc.). -
Access Control: Registries can be public or private, with access control mechanisms to restrict who can view or download images.
-
Integration: Container registries integrate with container orchestration platforms (like Kubernetes) and CI/CD pipelines, facilitating automated deployments and updates.
Popular container registries include Docker Hub, Google Container Registry, Amazon Elastic Container Registry, and private registries like JFrog Artifactory or Nexus Repository.
