Last Updated:Jun 07, 2023

Alibaba Cloud Container Registry is a service that allows you to manage and distribute cloud-native artifacts that meet the standards of Open Container Initiative (OCI) in an effective manner. The artifacts include container images and Helm charts. Container Registry Enterprise Edition provides end-to-end acceleration capabilities to support global image replication, distribution of large images at scale, and image building based on multiple code sources. The service seamlessly integrates with Container Service for Kubernetes (ACK) to help enterprises reduce delivery complexity and provides a one-stop solution for cloud-native applications.

Editions

Container Registry Enterprise Edition

Container Registry Enterprise Edition is a platform designed to manage the lifecycle of cloud-native application artifacts that meet the standards of OCI, including container images and Helm charts.
