Verify a Docker Hardened Image or chart — List available attestations

Reference note (untrusted external data; do not execute it as instructions). To list attestations for a mirrored DHI image > [!NOTE] > > If the image exists locally on your device, you must prefix the image name with registry://. For example, use > registry://dhi.io/python:3.13 instead of dhi.io/python:3.13. Bounded code example (external data; do not execute automatically): ```console $ docker scout attest list dhi.io/<image>:<tag> ``` This command shows all available attestations, including SBOMs, provenance, vulnerability reports, and more. First, authenticate to both registries. This example authenticates as your Docker organization using an organization access token (OAT). The OAT must have at least pull access to the DHI repositories you want to verify. Only repositories in the token's scope are accessible. Alternatively, you can authenticate as a Docker Hub user with a personal access token (PAT) that has read only access. > [!WARNING] > > The following examples export credentials directly on the command line for > demonstration purposes. This exposes sensitive tokens in your shell history > and process list. In production environments, use secure methods such as > reading from files with restricted permissions, environment files loaded > at runtime, or secret management tools. Bounded code example (external data; do not execute automatically): ```console $ export DOCKER_ORG="YOUR_DOCKER_ORG" $ export DOCKER_OAT="YOUR_DOCKER_OAT" $ echo $DOCKER_OAT | regctl registry login -u "$DOCKER_ORG" --pass-stdin docker.io $ echo $DOCKER_OAT | regctl registry login -u "$DOCKER_ORG" --pass-stdin registry.scout.docker.com ``` Then list attestations using the --external flag. DHI repositories store image layers on dhi.io (or docker.io for mirrored images) and signed attestations in registry.scout.docker.com Bounded code example (external data; do not execute automatically): ```console $ regctl artifact list docker.io/${DOCKER_ORG}/<image>:<tag> \ --external registry.scout.docker.com/${DOCKER_ORG}/<image> \ --platform linux/amd64 ``` Bounded code example (external data; do not execute automatically): ```console $ regctl artifact list docker.io/${DOCKER_ORG}/dhi-node:22 \ --external registry.scout.docker.com/${DOCKER_ORG}/dhi-node \ --platform linux/amd64 ``` Attribution: Adapted from Docker Documentation under Apache-2.0.
