Limits on new Personal Edition instances - Container Registry

Starting September 4, 2024, each new Container Registry (ACR) Personal Edition instance is bound to a single region and assigned an exclusive endpoint, which improves the security and stability of instance access. This topic describes the restrictions that apply to these instances.

Changes

Starting September 4, 2024, you must select a region when creating an ACR Personal Edition instance. After creation, the instance can only be used in the selected region. For more information, see [Product update] Announcement on the adjustment of Container Registry Personal Edition and Supported regions.

Each new Personal Edition instance is automatically assigned an exclusive endpoint to improve data isolation and access efficiency. You can access your instance only through this endpoint. The following restrictions apply:

New Personal Edition instance endpoints are not supported in pulling images within the same account.
Harbor remote replication cannot synchronize images to new Personal Edition instance endpoints.
Only one RAM user can set the image repository login password.
Public endpoints cannot be used to pull images.

Performance and rate limiting

New Personal Edition instances use a shared bandwidth model with no guaranteed egress bandwidth. Speed fluctuations may occur during peak hours. Frequent image pulls trigger a TOOMANYREQUESTS error because the shared resource rate limit is reached.

To avoid triggering rate limiting, follow these recommendations:

Keep concurrent image pulls below 10.
Reduce pull frequency and avoid sending burst requests within a short time window.
Push frequently used base images to an ACR repository in the same region and account. This reduces cross-account or cross-region pulls.
If you need higher pull performance and stability, upgrade to an Enterprise Edition instance for dedicated resources.

New and legacy Personal Edition endpoints

New Personal Edition endpoints: Start with crpi- and end with .personal.cr.aliyuncs.com.
Examples:
- crpi-xxxx.cn-hangzhou.personal.cr.aliyuncs.com (public endpoint)
- crpi-xxxx-vpc.cn-hangzhou.personal.cr.aliyuncs.com (VPC endpoint)
Legacy Personal Edition endpoints: Start with registry.
Examples:
- registry.cn-hangzhou.aliyuncs.com (public endpoint)
- registry-vpc.cn-hangzhou.aliyuncs.com (VPC endpoint)
Note
Legacy Personal Edition instances cannot be deleted, so you cannot switch regions by recreating an instance. If you no longer use a legacy instance, manually delete the repositories and images inside it to free up storage. Legacy instances do not incur charges.
