@ZYecho I installed the pouch-1.3.0-1.el7.x86_64.rpm in centos7.6.1810,

pouch pull hello-world that from registry.hub.docker.com/library/hello-world:latest then save the hello-world image to a offline one. pouch save registry.hub.docker.com/library/hello-world:latest -o hello-world.tar

and last execute the below command pouch load -i hello-world.tar

the terminal shows "failed to import image into containerd by tarstream: unrecongnized image format"

the pouch version is:

Version: 1.3.0 APIVersion: 1.2.4 Arch: amd64 BuildTime: 219-06-13T11:25:25 GitCommit: 1.3.0 GoVersion: go.1.10.4 KernelVersion: 3.10.0-957.12.1 Os: linux

When the image is multiple platform, it will be fail because pouchcontainer only downloads the default platform, for example, linux/amd64. It can be fixed by updated containerd version. It will be fixed late
