Policy-as-Code: End-to-End Enforcement

When to Use This Skill

Policy-as-Code ensures compliance through automated enforcement at three critical checkpoints:

graph LR
    A[Local Development] -->|Push Code| B[CI Pipeline]
    B -->|Deploy| C[Runtime Admission]

    A -->|policy-platform container| A1[Kyverno CLI]
    B -->|policy-platform container| B1[Kyverno CLI]
    C -->|Kyverno controller| C1[Admission Webhook]

The Core Principle: Same policies, three enforcement points. Zero gaps.

Prerequisites

  • Kubernetes cluster (for runtime deployment)
  • Container runtime (Docker/Podman for local dev)
  • CI platform (GitHub Actions, Bitbucket Pipelines, GitLab CI)
  • Basic Kyverno knowledge (see Kyverno guide)

Implementation

Start Local, Scale Up

Test policies locally first. Fix violations in seconds, not hours. Only after local validation works should you move to CI integration and runtime deployment.

Step 1: Run policies locally

docker run policy-platform:latest \
  kyverno apply /repos/security-policy/ \
  --resource deployment.yaml

Step 2: Add to CI pipeline

- name: Policy Check
  image: policy-platform:latest
  script:
    - kyverno apply /repos/security-policy/ --resource app.yaml

Step 3: Deploy Kyverno to cluster

helm install kyverno kyverno/kyverno -f kyverno-values.yaml
helm install policy-reporter policy-reporter/policy-reporter

Key Principles

1. Single Source of Truth

Policies live in Git repositories. Everything derives from there.

2. Container-Based Distribution

One container runs everywhere. No "works on my machine."

3. Progressive Enforcement

Local (warn) → CI (fail) → Runtime (block).

4. Separation of Concerns

  • Policy repos: Define rules
  • Policy-platform: Package and distribute
  • Kyverno: Enforce at runtime
