GitHub CLI (gh) can be used to retrieve the build provenance, which details the exact commit, workflow, and runner that produced the image:
- Production image
gh attestation verify \
--owner gitguardian \
oci://ghcr.io/gitguardian/wolfi/traefik:latest- Shell image
gh attestation verify \
--owner gitguardian \
oci://ghcr.io/gitguardian/wolfi/traefik:latest-shellAll official images are cryptographically signed using Sigstore Cosign.
To ensure the image is authentic and has not been tampered with, use the following command:
- Production image
cosign verify \
--certificate-oidc-issuer=https://token.actions.githubusercontent.com \
--certificate-identity=https://github.com/GitGuardian/wolfi/.github/workflows/release.yaml@refs/heads/main \

ghcr.io/gitguardian/wolfi/traefik:latest-shell | jqTo enhance transparency, we generate SBOMs for each release. SBOMs are available directly from the container registry and can be verified using using Sigstore Cosign.

ghcr.io/gitguardian/wolfi/traefik:latest-shellThis will pull in the signature for the attestation specified by the --type parameter, which in this case is the SPDX attestation. You will receive output that verifies the SBOM attestation signature in cosign's transparency log:
Verification for ghcr.io/gitguardian/wolfi/traefik:latest --
The following checks were performed on each of these signatures:
- The cosign claims were validated
- Existence of the claims in the transparency log was verified offline
- The code-signing certificate was verified using trusted certificate authority certificates

...To download an attestation, use the cosign download attestation command and provide both the predicate type and the build platform. For example, the following command will obtain the SBOM for the python image on linux/amd64:
- Production image
cosign download attestation \
--platform=linux/amd64 \
--predicate-type=https://spdx.dev/Document \
ghcr.io/gitguardian/wolfi/traefik:latest | jq -r .payload | base64 -d | jq .predicate- Shell image
