Overview
Docker Hardened Images include comprehensive security attestations that verify the image's build process, contents, and security posture. This image is built using SLSA Build Level 3 practices. Additionally, this image includes a source attestation that links to a corresponding source image containing all build materials. The following attestations are available and can be verified using cosign.
Docker's DHI public key is available at https://registry.scout.docker.com/keyring/dhi/latest.pub and also archived at https://github.com/docker-hardened-images/keyring.
How to verify attestations
1. List all available attestations
docker scout attest list dhi.io/ruby:4-alpine3.23-dev2. Verify a specific attestation
For example, to verify the SLSA provenance attestation:
docker scout attest get dhi.io/ruby:4-alpine3.23-dev --predicate-type https://slsa.dev/provenance/v0.2 --verifyAttestations
All attestations are signed and can be verified with cosign.
