could not parse reference

[aep-sunlife]

When I try to scan locally built Docker images with the Docker Scout GUI, then I get a security report.

However, when I use the Docker Scout CLI, then it crashes with a strange error trace. I think the error handling may be broken.

$ docker images
REPOSITORY                         TAG               IMAGE ID       CREATED          SIZE
SecOps/hello-world-ant             latest            0d023c25ffb5   3 minutes ago    251MB

$ docker scout cves -e SecOps/hello-world-ant

 Display CVEs identified in a software artifact

Usage
  docker scout cves [OPTIONS] [IMAGE|DIRECTORY|ARCHIVE]

Description
The docker scout cves command analyzes a software artifact for vulnerabilities.

If no image is specified, the most recently built image is used.

The following artifact types are supported:

- Images
- OCI layout directories
- Tarball archives, as created by docker save
- Local directory or file
- SPDX file or in-toto attestation file with SPDX predicate

The tool analyzes the provided software artifact, and generates a vulnerability report.

By default, the tool expects an image reference, such as:

- redis
- curlimages/curl:7.87.0
- mcr.microsoft.com/dotnet/runtime:7.0

If the artifact you want to analyze is an OCI directory, a tarball archive, a local file or directory,
or if you want to control from where the image will be resolved, you must prefix the reference with one of the following:

- image:// (default) use a local image, or fall back to a registry lookup
- local:// use an image from the local image store (don't do a registry lookup)
- registry:// use an image from a registry (don't use a local image)
- oci-dir:// use an OCI layout directory
- archive:// use a tarball archive, as created by docker save
- fs:// use a local directory or file
- sbom:// use an SBOM as SPDX file or in-toto attestation file with SPDX predicate or syft json SBOM file

ERROR   Status: could not parse reference: SecOps/hello-world-ant, Code: 1

Also tried using the option to scan the most recently built image:

$ docker scout cves
    ✓ SBOM of image already cached, 201 packages indexed
ERROR   Status: could not apply VEX statements: could not parse image name: could not parse reference: SecOps/hello-world-ant, Code: 1

Tried configuring export DOCKER_DEFAULT_PLATFORM='linux/amd64'.

Tried explicitly providing --platform linux/amd64

Tried rebuilding the image without the SecOps/ prefix.

Tried referencing the image with an explicit :latest tag suffix.

Tried removing the -e option for meaningful exit codes.

Tried macOS and Windows.

Tried Docker Scout 14 and Docker Scout 15.

Tried relaunching Docker.

Tried docker system prune -f.

No change in behavior.

To clarify, the image is built with conventional docker build -t <name> . commands, no special sauce.

@mcandre, this is another issue with the different interpretations of the OCI spec. While docker build supports creating images with names like SecOps/hello-world-ant other commands don't support them. Those names are not compatible with the OCI spec which is why this is failing in our of our dependencies. If you can lowercase the namespace part of your image name, it would work.

More oddities, when trying to pull this image:

❯ docker pull SecOps/hello-world-ant
Using default tag: latest
Error response from daemon: failed to resolve reference "SecOps/hello-world-ant:latest": failed to do request: Head "https://SecOps/v2/hello-world-ant/manifests/latest": dialing SecOps:443 container via direct connection because  has no HTTPS proxy: connecting to SecOps:443: dial tcp: lookup SecOps: no such host

Interesting.

Please apply validation, with a message indicating that the requested image name uses nonportable characters, with a URL to some documentation on standardized image names.
