Kritis (“judge” in Greek), is an open-source solution for securing your software supply chain for Kubernetes applications. Kritis enforces deploy-time security policies using the Google Cloud Container Analysis API, and in a subsequent release, Grafeas.

Here is an example Kritis policy, to prevent the deployment of Pod with a critical vulnerability unless it has been allowlisted:

  maximumSeverity: HIGH
    - providers/goog-vulnz/notes/CVE-2017-1000082
    - providers/goog-vulnz/notes/CVE-2017-1000081

In addition to the enforcement this project also contains signers that can be used to create Grafeas Attestation Occurrences to be used in other enforcement systems like Binary Authorization. (TODO#571: add doc and fix link) For details see upcoming doc Kritis Signer.
