Docker save -o, Docker load -i show another Layers of the image

[MaxZapletin]

Description

Hello, everyone.
I have the private repository in amazon ECR. I’m pulling the image to the one host, and trying to make docker save to deliver the image to another host. This way i don’t need to download fully the new upgrade image because of the problem with the internet connection and just pull the few layers that i need to update.

The issue is, That when i make docker load -i, i see another layers and when i pulling update image, i see that docker start download fully all layers that have already been at another host from where i brought the image.

Reproduce

docker save -o test.tar "image-main121212"
docker load -i test.tar

Expected behavior

It's should be the same layers?

Anybody know something?

Does this issue happen with this image specifically or do you have a public image we can use to reproduce?

[MaxZapletin]

Hey, thank you for response.
It's happen with all images... You can try to download image and after that Save to archive and you will see differnet UUID of layers.
Look at attached pic, You can see that for the same image layers is deferents.
