Replicating Custom Images Across Regions

Last updated: 2023-08-29 14:14:55


    With Cross-Region Replication, you can replicate a custom image to multiple destination regions, and create Lighthouse instances in the destination regions with the replicated image.


    An image cannot be replicated between the Chinese mainland and other countries/regions. When an image is replicated to a destination region, it consumes the custom image quota in this region and be charged as a custom image. For more information, see Custom Image Pricing.
    It usually takes 15 to 40 minutes to replicate an image.
    You can replicate an image to up to 10 destination regions at one time.


    1. Log in to the Lighthouse console and select Image on the left sidebar.
    2. Select the region at the top of the Image page and click the Custom image tab.
    3. Select More > Cross-region replication on the right of the target image in the list.
    4. In the Cross-region replication window that pops up, read the precautions, and click OK. After the replication is completed:
    You can find an image with the same name but a different ID in the list.
    You can use the image to create an instance in the destination region. For detailed steps, see Working with Custom Images.
