Case1 can use the method that ks-installer to synchronize the images to aliyun repo .

https://github.com/kubesphere/ks-installer/blob/28d9ff017d05ffdedabcbe47ec6e68afe9cd2b3e/.github/workflows/sync-release-images.yml#L18

This method uses skopeo, which is a very useful images synchronization tool.
