Description

When trying to push multiplatform images using ctr , receiving the following error.

ctr: failed commit on ref "index-sha256:15303a32445f10470c0a8acde338002985f909c9b275d988202ad5cf5e04b247": cannot reuse body, request must be retried

I find this issue is kind of flaky or due to a race condition as this does not happen always. The error message displayed is coming from #3431

Steps to reproduce the issue

1. Fetch the image using
   ctr content fetch --all-platforms docker.io/akhilerm/node-disk-manager:ci
2. Push the image to a different registry with a different tag

ctr images push quay.io/akhilerm/node-disk-manager:ci docker.io/akhilerm/node-disk-manager:ci

3. Try to push the same image again to the same repository with a different tag

ctr images push quay.io/akhilerm/node-disk-manager:latest docker.io/akhilerm/node-disk-manager:ci

Describe the results you received and expected

The following errors gets reported when the second tag is pushed.

ctr: failed commit on ref "index-sha256:15303a32445f10470c0a8acde338002985f909c9b275d988202ad5cf5e04b247": cannot reuse body, request must be retried

Additional details that I observed:
The push was always succeeding with the first tag, but failed in the subsequent pushes. Also, when a different source image was used, the push succeeds sometimes.

Expected:
The error should not happen and the multiplatform images should be pushed successfully.

What version of containerd are you using?

v1.3.0-4011-g0fdbd450d 0fdbd45

Any other relevant information

• The containerd version shows as 1.3.0, but I had built it from source after checking out to v1.5.5
• I had made a single commit on top of 1.5.5 to add support for allowing auth from docker config, which I believe does not interfere with the pusher.

• containerd is running in a docker container for fetching and pushing images
• The error message comes from the changes in PR Fix bug in setting request body #3431
• The same error is being reported by buildkit push action which is believe is using containerd . Ref GAR error "cannot reuse body, request must be retried" docker/build-push-action#452
