Current implementation of images inspect is faulty (eg: RepoTags)

[apostasie]

Description

nerdctl does not deal properly with images bounds to multiple tags.

Steps to reproduce the issue

Compare:

sudo ./nerdctl pull dubodubonduponey/testouille
sudo ./nerdctl pull dubodubonduponey/testouille:2
sudo ./nerdctl inspect dubodubonduponey/testouille
sudo ./nerdctl inspect XXXXXXX

with

docker pull dubodubonduponey/testouille
docker pull dubodubonduponey/testouille:2
docker inspect dubodubonduponey/testouille
docker inspect XXXXXXX

Describe the results you received and expected

1. when querying by reference, nerdctl returned result has in RepoTags ONLY the name used to query, regardless of the fact other tags may hold the same image
2. when querying by id (that is bound to multiple tags), nerdctl returns multiple distinct images instead of just one

Compare with docker behavior.

What version of nerdctl are you using?

1.7.6

Are you using a variant of nerdctl? (e.g., Rancher Desktop)

None

Note that the implementation is

nerdctl/pkg/cmd/image/inspect.go

Line 34 in 4fff6b2

func Inspect(ctx context.Context, client *containerd.Client, images []string, options types.ImageInspectOptions) error {

is problematic from the get-go, not just the implementation of ImageFromNative.

It assumes that every successive image returned from the walker needs a different entry.
