    OPA: While OPA is an open-source, general-purpose policy engine capable of enforcing unified and context-aware policies throughout the stack, it can also accept and output data in formats such as JSON, effectively functioning as a tool for generating or modifying configurations. Although it does not provide out-of-the-box schema definition support, it allows the integration of JsonSchema definitions.
  • Securing CI/CD Images with Cosign and OPA

    In essence, container image signing involves adding a digital stamp to an image, affirming its authenticity. This digital assurance guarantees that the image is unchanged from creation to deployment. In this blog, I'll explain how to sign container images for Kubernetes using Cosign and the Open Policy Agent. I will also share a tutorial that demonstrates these concepts.

  • CIAM vs. IAM: What's the difference (2022)
    2 projects | news.ycombinator.com | 11 May 2023
    CIAM is not nearly as popular of a term as it needs to be. When most developers build apps today, they still look at their cloud provider's IAM or Active Directory for inspiration in design of their customer-facing systems. I think this article is actually understating the complexity. Conway's Law rules all and sometimes your systems and users won't even necessarily be in your control. I urge folks to look into policy engines like OPA[0] and ReBAC systems like SpiceDB[1] rather than reinventing the wrong wheel.

  • You Broke Reddit: The Pi-Day Outage
    3 projects | /r/RedditEng | 21 Mar 2023
    At this point, someone spotted that we were getting a lot of timeouts in the API server logs for write operations. But not specifically on the writes themselves. Rather, it was timeouts calling the admission controllers on the cluster. Reddit utilizes several different admission controller webhooks. On this cluster in particular, the only admission controller we use that’s generalized to watch all resources is Open Policy Agent (OPA). Since it was down anyway, we took this opportunity to delete its webhook configurations. The timeouts disappeared instantly… But the cluster didn’t recover.
