In order to set up provenance and attestations for Pod Security in a Kubernetes environment, you'll need to utilize tools that enhance security and provide evidence of the software supply chain's integrity. Below are some steps and examples to help you get started.
# Install the necessary tools
kubectl apply -f https://path-to-your/pod-security-policy.yaml
# Create a policy
apiVersion: policy/v1beta1
kind: PodSecurityPolicy
metadata:
name: my-restricted-policy
spec:
privileged: false
...
# Generate an attestation
kind: WorkloadAttestation
apiVersion: attestations/v1alpha1
metadata:
name: my-attestation
spec:
attestation: "my-attestation-criteria"
For a detailed implementation, consider integrating tools such as Notary or Grafeas for managing and verifying the authenticity of images and workloads. You can also explore Open Policy Agent (OPA) for fine-grained control over Kubernetes resources.
