Research direction

Start by reproducing the reported docker save --platform=linux/amd64 command with kserve/llmisvc-controller:v0.20.0, then trace how the CLI selects the platform from the local image index. Done means docker save emits a usable archive for linux/amd64 and ctr images import accepts it without the unrecognized image format error.

Description

Hi there,

I'm trying to pull an image in my docker and then import it in my Kubernetes cluster's nodes (build by Kind). the pulls seem successful.

$ docker pull --platform=linux/amd64 kserve/llmisvc-controller:v0.20.0
v0.20.0: Pulling from kserve/llmisvc-controller
Digest: sha256:d502b5b56713b12d0e04127cdea76bd935402a0d7870d3c30dbf730349d86a95
Status: Image is up to date for kserve/llmisvc-controller:v0.20.0
docker.io/kserve/llmisvc-controller:v0.20.0

But when I import them in Kind nodes:

$ docker save --platform="linux/amd64" "kserve/llmisvc-controller:v0.20.0" | docker exec --privileged -i "cluster-demo-worker2" ctr --namespace=k8s.io images import --snapshotter=overlayfs -
Error response from daemon: no suitable export target found: image with reference kserve/llmisvc-controller:v0.20.0 was found but does not provide the specified platform (linux/amd64)
ctr: unrecognized image format
Reproduce

docker pull --platform=linux/amd64 kserve/llmisvc-controller:v0.20.0
docker save --platform="linux/amd64" "kserve/llmisvc-controller:v0.20.0" | echo

Expected behavior

No response
