Simple Application Server:Copy a custom image

Last Updated:Jan 30, 2024

You can copy a custom image from one region to another region and then use the copy of the custom image to create a simple application server. This way, you can seamlessly migrate data between simple application servers across regions. You can also use the shared custom image feature to share the copy of the custom image to Elastic Compute Service (ECS). Then, you can use the shared image copy to create ECS instances. This way, you can seamlessly migrate data from a simple application server to an ECS instance across regions. This topic describes how to copy a custom image of a simple application server.

Prerequisites

A custom image is created. For more information, see Create a custom image.

Background information

If you want to create a simple application server that has the same configurations as your existing simple application server in a different region, you can use the image copy feature. After a source simple application server is configured, and a custom image is created from the source simple application server and copied to the destination region, you can use the copy of the custom image to create simple application servers in the destination region. These simple application servers have the same configurations as the source simple application server.

Take note of the following items:

  • To copy a custom image, Alibaba Cloud needs to create a snapshot of the source image in the destination region. You cannot view this snapshot. Snapshots and custom images generated by using the image copy feature consume the resource quota of your Alibaba Cloud account. For more information, see Limits on other resources.

  • If the custom image generated by using the image copy feature is deleted, the simple application servers that are created from the custom image cannot be reset.

Procedure

  1. Log on to the Simple Application Server console.

  2. In the left-side navigation pane, click Image.

  3. On the Images page, find the custom image that you want to copy.

  4. In the Actions column, choose image.png > Copy Image.

  5. In the Copy Image dialog box, configure parameters based on your business requirements.

    Parameter description:

    • Destination Region: Select a destination region to which you want to copy the custom image.

    • Name of the custom image: Enter a name for the copy of the custom image for identification. Example: testcopyimage.

    • Description: Enter a description for the copy of the custom image. The default description contains the ID and region of the custom image. You can modify the description.

  6. (Optional) Select I have understood and agreed to the Cross-border Compliance Commitments.

    The Cross-border Compliance Commitments are displayed only if you select a cross-border region for the Destination Region parameter.

  7. Click Confirm.

    You can view the information of the custom image in the Copying state on the Image page. Wait until the image copy task is complete.

    Note

    The Server ID/Name column of the custom image copy in the destination region is empty.
