　　Aliyun How to share mirrors

You can share your own custom mirrors with other users, who can query the shared mirror list of this account with other accounts through the admin console or the ECS API. Shared users can create ECS instances and replace system disks using mirrors shared by other accounts.

Before sharing your account with other accounts, verify that sensitive and secure important data and software are present on the mirror.

Note: Aliyun does not guarantee the integrity and security of shared mirrors for other accounts, and uses shared mirrors to take risks. Please select the account you trust to share with your mirror. When you use this mirror to create an ECS instance, log on to the ECS instance to check to verify the security and integrity of the mirror.

Attention matters

Limit

You can get up to 30 shared mirrors per user.

You can share up to 50 users per mirror.

Shared mirrors do not occupy their own mirrored places.

Shared mirrors are geographically restricted when creating instances, the same as the shared source geography.

Other accounts shared with your account can no longer be shared with other people. Only the owner of the mirror can share it with another account.

Effects of removing shared mirrors

If your custom mirror is already shared with another account, the image can still be deleted, but first you need to remove all of the relationships for that custom mirror.

If you delete a shared account for a custom mirror, the user cannot query the mirror through the admin console or the ECS API, and you cannot use that image to create an ECS instance and replace the system disk.

When a shared mirror is deleted, it causes a failure to reinitialize the system disk with an ECS instance created with a shared mirror.

Operation Steps

The steps for sharing mirrors from the console are as follows:

Log on to the Cloud Server Management Console.

Click a mirror in the left navigation. You can see a mirrored list.
