What problem does it solve?

GitLab attestations help teams verify software supply chain provenance by proving the origin and integrity of artifacts across project releases and CI/CD pipelines.

Core Features & Use Cases

Verify attestations for artifacts and projects using GitLab's Attestations API and SLSA provenance.
Inspect provenance data and link it to artifact verification and security audits.
Use in CI/CD workflows to enforce attestation checks before deployments.

Quick Start

Run glab attestation verify <project_id> <artifact_path> to verify the provenance of a specific artifact.

FAQPage Schema

How do I verify GitLab artifact provenance in a CI/CD pipeline?▼

To verify GitLab artifact provenance in a CI/CD pipeline, run glab attestation verify with the project ID and artifact path. This validates the attestation to confirm artifact origin and integrity before deployment.

Do I need cosign to validate GitLab attestations?▼

Yes, you need cosign installed to validate GitLab attestations. The verification process relies on cosign to cryptographically verify the attestations and confirm the provenance and integrity of your artifacts.

What is GitLab attestation verification used for?▼

GitLab attestation verification is used to prove the origin and integrity of artifacts across project releases. It enforces supply chain security policies during project audits and CI/CD workflows by validating SLSA provenance data.

Can I inspect SLSA provenance data for a GitLab project release?▼

Yes, you can inspect SLSA provenance data for a GitLab project release. The attestation Skill integrates with GitLab APIs to inspect provenance data and link it directly to artifact verification and security audits.

Does GitLab attestation verification work for security reviews?▼

Yes, GitLab attestation verification works for security reviews. It validates artifact provenance and integrity using GitLab's Attestations API, allowing security teams to enforce supply chain policies and audit artifact origins.

What are the limitations of validating GitLab attestations with cosign?▼

A limitation of validating GitLab attestations is the strict dependency on cosign for verification operations. Additionally, proper validation requires correct project IDs and artifact paths to successfully integrate with GitLab APIs.
