Context
An image tag can point to a different artifact later, making a release difficult to reconstruct. Supply-chain review needs a durable link between the deployed artifact and the build process that produced it. Build metadata helps establish that link, but its meaning depends on how it is generated and verified.
Identify the artifact being reviewed
Record the registry, image digest, source revision and build job associated with the release. Use the immutable artifact identity when comparing environments rather than assuming a mutable tag always identifies the same content. Document which build system is trusted to create production artifacts. Include external base images and build-time dependencies in the review scope where applicable. Keep registry credentials out of build evidence shared with business stakeholders or outside support teams.
Understand the attached metadata
Docker's build-attestation documentation describes metadata such as provenance and software bills of materials. Review which attestations the actual build creates, where they are stored and which consumers retain them. A metadata document existing beside an image does not automatically establish that the builder was trusted or that a deployment verified it. Clarify the verification step and the trust assumptions. Avoid presenting a software inventory as a guarantee that every dependency is free of vulnerabilities or business-logic defects.
Connect review to the deployment decision
Define which evidence must be present before an artifact is promoted. Check how the registry, scanner and deployment tooling handle the metadata and supported artifact formats. Test a release with missing or unexpected evidence and confirm the intended response. Keep approval tied to the artifact digest so a later tag update does not silently replace what was reviewed. Separate build provenance, vulnerability review and application acceptance checks; they answer different questions and should not be collapsed into one green badge.
Retain a useful release record
Store the artifact identity, build reference, relevant attestations and approval outcome with the deployment history. Confirm that authorized responders can retrieve them after a release incident. Review retention when registries automatically remove old images or metadata. Rehearse how a team identifies the artifact running in production and compares it with the approved build. The operational result should be a traceable release boundary with clear verification ownership, not a claim that enabling one build option makes the entire software supply chain secure.
