Synchronizing an Image to Other Regions

Scenarios

You can synchronize newly pushed images to other regions either automatically or manually. Automatic synchronization can be performed for a single image or multiple images.

After you configure automatic image synchronization, new and updated images will be automatically synchronized to repositories of other regions. However, images that were pushed before automatic image synchronization was configured will not be automatically synchronized.

You can manually synchronize them by referring to Can Existing Images be Automatically Synchronized?
