Enabling the containerd image store via > docker/setup-docker-action allows BuildKit to store attestations locally > without pushing to a registry first. Without the containerd image store, > Docker Engine rejects the build with: Attestation is not supported for the docker driver. > Switch to a different driver, or turn on the containerd image store, and try again. > The Push image step runs only if the scan passes, using if: success() > to ensure images are only pushed to the registry when they are free of > critical or high-severity vulnerabilities.\n\nFor more details on using Docker Scout in CI, see Integrating Docker Scout with other systems.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
