How do I set up provenance and attestations for Kubernetes services?

Setting up provenance and attestations for Kubernetes services is crucial for ensuring the security and integrity of your applications. This guide will walk you through the steps to implement provenance and attestations using tools like SPIFFE/SPIRE and Open Policy Agent (OPA).

Provenance in Kubernetes usually focuses on tracking the origin and transit of workloads and their associated metadata, while attestations are used to verify that the workloads are compliant with your security policies.

Here’s an example setup that integrates provenance and attestation into your Kubernetes services:

// Example pseudocode for setting up SPIFFE with Kubernetes apiVersion: spiffe.io/v1beta1 kind: FederatedTrustDomain metadata: name: my-trust-domain spec: trustDomain: example.com // Attestation Policy using OPA package kubernetes.attestation default allow = false allow { input.request.kind.kind == "Pod" input.request.operation == "CREATE" input.request.user == "system:serviceaccount:my-namespace:my-service-account" }
