The P2P acceleration feature V2.0 of Container Registry Enterprise Edition The P2P acceleration feature of Container Registry Enterprise Edition is upgraded to V2.0. The following capabilities are provided by the upgraded feature:
  • Allows you to install the P2P component on the Add-ons page in the Container Service for Kubernetes (ACK) console or in on-premises Kubernetes clusters, and allows you to use the P2P acceleration feature in the cluster without the need to deploy accelerated images.
  • Supports accelerating the image distribution among more than 1,000 nodes in P2P mode. V2.0 can speed up the image download by 100%.
  • Supports image distribution in P2P mode among the nodes of the clusters that use both Elastic Compute Service (ECS) instances and elastic container instances. This improves the response speed in elastic scaling scenarios.
  • Supports image distribution in P2P mode among multiple clusters that are deployed in different virtual private clouds (VPCs). This improves the flexibility of image distribution.
Container Registry Enterprise Edition instances All regions Use P2P acceleration

Upgrade of the image building feature in Container Registry Enterprise Edition Container Registry Enterprise Edition upgrades the image building feature from multiple dimensions, such as the diversity of source code repositories, building speed, and user experience. The following capabilities are provided by the upgraded feature:
  • Accesses the source code repositories of Apsara DevOps Codeup and Gitee and automatically triggers image building when the code in the source code repositories changes. This improves the efficiency of R&D and iteration.
  • Accelerates image building based on multi-level cache policies and data centers outside mainland China. This improves the image building speed by 30%.
  • Supports build rules that are based on image tags and build settings that allow you to build images as needed. This improves the user experience and efficiency in implementing cloud-native DevOps solutions.
Container Registry Enterprise Edition instances All regions Use Container Registry Enterprise Edition to build images

Image version cleanup for an instance The number of image versions increases as the container-based business develops and iterates. The increasing number leads to complex image maintenance and high cost. Container Registry allows you to configure retention policies to delete image versions for an instance as needed. You can retain a specific number of recent images or images that match the specified regular expression. Other expired image versions are automatically deleted. Container Registry Enterprise Edition instances China (Beijing), China (Hangzhou), and China (Shanghai)

On-demand image loading Container Registry provides this feature to accelerate image loading in elastic scaling scenarios that require short cold start time and AI-based scenarios where large images slow the distribution. Container Registry can convert a standard container image to an accelerated image. Then, you can install the aliyun-acr-acceleration-suite component on worker nodes of an ACK cluster. Pods that are scheduled to the worker nodes load resources of images on demand and decompress image packages online. This feature reduces the average time to start a container by 60% and quadruples the speed of application distribution. This ensures that images are run with high efficiency. Container Registry Enterprise Edition instances China (Hangzhou), China (Shanghai), US (Virginia), and US (Silicon Valley) Load resources of a container image on demand

Custom domain names You can bind a custom domain name that has a Secure Sockets Layer (SSL) certificate to an instance. Then, you can use the custom domain name to access the instance over HTTPS. Container Registry Enterprise Edition instances All regions Use a custom domain name to access a Container Registry Enterprise Edition instance
Migration from a self-managed Harbor instance to a Container Registry Enterprise Edition instance You can migrate images from a self-managed Harbor instance to a Container Registry Enterprise Edition instance. This helps you save the cost of creating and maintaining an image registry by yourself. Container Registry Enterprise Edition instances All regions Migrate images from a self-managed Harbor instance to Container Registry Enterprise Edition in 10 minutes

Upgrade of global image synchronization links The global image synchronization links are upgraded to support automatic image synchronization across major regions around the world. Container Registry provides a synchronization success rate higher than 99% and ensures efficient image distribution and iteration on a global scale. You can configure sync rules for Container Registry Enterprise Edition instances to synchronize images by namespace or repository. In addition, Internet access is not required for synchronizing images in Container Registry Enterprise Edition instances. This improves the convenience and security of image synchronization. Container Registry Enterprise Edition instances All regions None

Image signing Container Registry Enterprise Edition supports image signing. This prevents man-in-the-middle (MITM) attacks and unauthorized image updates or deployments. This way, image consistency and security from distribution to deployment are ensured. Container Registry supports automatic image signing by namespace. Every time an image is pushed to Container Registry, Container Registry automatically signs the image based on the matched signature rule. This ensures that your container images are trustworthy. Container Registry Enterprise Edition instances All regions Sign container images
