layer is not pulled when using the 'nerdctl pull'

[yankay]

Description

Relate to the #2327

The content digest sha256:xxx: not found is becuase of the nerdctl does not pull the layer.

In my environment:

/usr/local/bin/nerdctl --namespace=nerdctl-test  save -o /tmp/haha.tar ghcr.io/stargz-containers/alpine:3.13-org
FATA[0000] failed to get reader: content digest sha256:ca3cd42a7c9525f6ce3d64c1a70982613a8235f0cc057ec9244052921853ef15: not found

And try to pull with nerdctl

root@kay201:~/oss/containerd# nerdctl  -n nerdctl-test pull ghcr.io/stargz-containers/alpine:3.13
-org

It skips the layer file. And the content digest is still not found.

And then try to pull with ctrctl

root@kay201:~/oss/containerd#  ctr  -n nerdctl-test i pull ghcr.io/stargz-containers/alpine:3.13-org
ghcr.io/stargz-containers/alpine:3.13-org:                                        resolved       |++++++++++++++++++++++++++++++++++++++|

The layer file can be pulled and the content digest can be found.

Steps to reproduce the issue

1. nerdctl -n nerdctl-test pull ghcr.io/stargz-containers/alpine:3.13-org
2. ctr -n nerdctl-test content rm sha256:ca3cd42a7c9525f6ce3d64c1a70982613a8235f0cc057ec9244052921853ef15
3. nerdctl -n nerdctl-test pull ghcr.io/stargz-containers/alpine:3.13-org
4. nerdctl --namespace=nerdctl-test save -o /tmp/haha.tar ghcr.io/stargz-containers/alpine:3.13-org

FATA[0000] failed to get reader: content digest sha256:ca3cd42a7c9525f6ce3d64c1a70982613a8235f0cc057ec9244052921853ef15: not found

Describe the results you received and expected

The content digest exist, like using the ctrctl

Any update on this? Seems like I am facing similar issue. Any workaround to pull the image again preferably via nerdctl?

ghcr.io/stargz-containers/alpine:3.13-org

Is this issue specific to ghcr.io/stargz-containers? Does docker.io/library/alpine work?

Hi @AkihiroSuda

It's the same with docker.io/library/alpine

The reproduce methods:

nerdctl -n nerdctl-test pull alpine:3.18.4
ctr -n nerdctl-test content rm sha256:96526aa774ef0126ad0fe9e9a95764c5fc37f409ab9e97021e7b4775d82bf6fa
nerdctl -n nerdctl-test pull alpine:3.18.4
nerdctl --namespace=nerdctl-test save -o /tmp/haha.tar alpine:3.18.4

I also have the same problem.

I downloaded the cephcsi image from Docker on my local macOS in order to use it in the production cluster. I then uploaded it through SFTP and it was used by Containerd. It worked!
