This article mainly introduces the method of importing existing image files into CVM ECS and appearing in the region as a custom image. It is very detailed and has a certain reference value. Friends who are interested must finish reading it.

ImportImage

Description

After importing a custom image, you can use the created custom image to create an ECS instance (RunInstances) or change the instance's system disk (ReplaceSystemDisk). When calling this interface, you need to be aware of:

You must upload the image file to the object store OSS in advance.

The region in which the image is imported must be the same as the region of the OSS Bucket uploaded by the image file.

The value range of n in parameter DiskDeviceMapping.n is [1,17]. N = 1 indicates the system disk, and n = [2,17] represents the data disk.

You cannot delete the mirror you are importing, you can only cancel the import mirror task (CancelTask).

You need to authorize ECS access to OSS for you in advance through the access control RAM service. Refer to the following steps:

Create a role AliyunECSImageImportDefaultRole. This must be the name, or the import of the image will fail. The strategy for the role is:

{"Statement": [{"Action": "sts:AssumeRole", "Effect": "Allow", "Principal": {"Service": ["ecs.aliyuncs.com"]}}], "Version": "1"}

Under this role, add the permission policy AliyunECSImageImportRolePolicy. This policy is the default policy for ECS to import images, or you can create a custom policy with permissions that include:

{"Version": "1", "Statement": [{"Action": ["oss:GetObject", "oss:GetBucketLocation"], "Resource": "*", "Effect": "Allow"}]}
