I don't have any inside information but the IBM blog post states: "IBM plans to deliver Grafeas and Kristis as part of the IBM Container Service on IBM Cloud, and to integrate our Vulnerability Advisor and DevOps tools with the Grafeas API."
Can you get some additional information? Have you tried to ask IBM? Maybe the author of the blog? Seems like I need to download this from GitHub in order to take a look at it right now?
