Image Creation FAQs¶
How Can I Use an ECS to Quickly Provision Identical ECSs?¶
If you have an ECS with applications deployed, you can use the ECS to create a private image and then use the image to create identical ECSs. In this way, you do not need to deploy applications repeatedly.
How Many Private Images Can I Create Under an Account?¶
Currently, you can create a maximum of 100 private images under an account in a region.
Do I Have to Stop the ECS Before Using It to Create a Private Image?¶
No. You can create an image from a running ECS. However, if data is written to the ECS during image creation, that new data will not be included in the created image.
Where Can I View the Image Creation Progress? How Long Does It Take to Create an Image?¶
Log in to the management console. Choose Computing > Image Management Service and click the Private Images tab. Monitor the image creation progress in the Status column.
The image creation involves the installation of KVM drivers, OS kernel loading, and GRUB boot configuration, which may take a long time. In addition, the network speed, image file type, and disk size have an impact on how long image creation takes.
Can I Select a Private Image Created Under a Subaccount When Creating an ECS Under the Main Account?¶
Yes.
Private images created under a subaccount are visible to the main account and all the other subaccounts (if any) under the main account.
If the private image is a system disk image or full-ECS image, you can select Private Image for Image when creating an ECS. Then, select this image from the drop-down list.
If the private image is a data disk image, select Create from image for Select Data Source when creating an EVS disk. Then, select this image in the displayed dialog box.
In addition, private images created under the main account are visible to all of its subaccounts.
