Anda dapat memanggil operasi CreateImageCache untuk membuat cache gambar. Hal ini mempercepat penarikan gambar dan mengurangi pengatur waktu mulai untuk instans Elastic Container Instance (ECI).
Deskripsi operasi
Precautions
-
Creating an image cache incurs fees. Review the billing information before you proceed. For more information, see Image cache billing.
-
Before you create an image cache, evaluate the total size of the images to be cached. If the total image size exceeds the cache size, the creation fails.
-
When you create an image cache, the system automatically creates an ECI instance and an Enhanced SSD (ESSD) PL1 disk. Do not delete the ECI instance or the disk during the creation process. Otherwise, the image cache cannot be created.
-
When you create an image cache, a corresponding snapshot is generated. Do not delete the snapshot. Otherwise, the image cache becomes invalid.
-
If you use a software development kit (SDK), make sure that you use one of the following versions or a later version: Java 1.0.10 or Python 1.0.7.
Usage suggestions
-
To enable password-free access for images from an ACR Enterprise instance that uses a custom domain name, set the AcrRegistryInfo parameters. When you set the AcrRegistryInfo parameters, you must also set the AcrRegistryInfo.N.InstanceId parameter.
-
If the image cache is used to create more than 1,000 ECI instances in a batch, set the StandardCopyCount and FlashCopyCount parameters to create multiple snapshot replicas. Multiple snapshot replicas are billed based on the incremental data size. Because the data in the snapshot replicas is the same, no additional fees are incurred.
When you call the CreateImageCache operation, the system automatically creates the service-linked role AliyunServiceRoleForECI. This role is used to access other Alibaba Cloud services such as ECS and VPC. For more information, see Service-linked role for Elastic Container Instance.
