Kyverno Consulting

Kyverno is an open-source Kubernetes policy engine focused on enforcing, validating, and mutating cluster resources using Policy-as-Code, and is maintained by the Cloud Native Computing Foundation (CNCF) community. It allows teams to define policies as Kubernetes-native resources (CRDs) and apply them consistently across clusters to improve governance, security, and operational standards. Common capabilities include validating manifests at admission time, automatically mutating resources to match best practices (for example, adding labels or security settings), generating related resources from templates, and reporting policy compliance for auditing. Kyverno is typically used to standardize configurations across namespaces and environments, enforce security controls (such as image registry restrictions or required Pod security settings), and automate guardrails for CI/CD-driven deployments; see the Kyverno documentation for policy syntax and feature details.

There are many advantages to using Orchestration tools:

• Improve the utilization of CPU, memory, and storage usage by running many processes on a single machine
• Manage the entire lifecycle of the orchestrated workloads: pre & post initialization & termination
• Control the scale of workloads and the scale of their underlying infrastructure separately
• Centralized management of workloads and infrastructure

Kyverno is a Kubernetes-native policy engine that enforces, validates, mutates, and generates resources using Policy-as-Code. It is used to standardize cluster governance, reduce misconfigurations, and improve compliance with minimal friction in day-to-day Kubernetes workflows.

• Defines policies as Kubernetes resources (CRDs), so policy changes can be reviewed, versioned, and deployed with the same GitOps and RBAC patterns as other cluster objects.
• Validates manifests at admission time to prevent risky configurations from being applied, such as privileged pods, missing required labels, or disallowed capabilities.
• Mutates resources to apply safe defaults and conventions automatically, such as adding labels/annotations, setting securityContext fields, or normalizing imagePullPolicy.
• Generates dependent resources to enforce baseline controls, such as creating NetworkPolicies, default RBAC, or standard config objects when namespaces are created.
• Audits existing cluster state to surface current violations, enabling teams to prioritize remediation without blocking deployments immediately.
• Supports scoped enforcement and policy exceptions, which helps teams roll out governance incrementally across namespaces, workloads, or environments.
• Includes a policy library and common patterns that accelerate implementation for typical Kubernetes security and compliance requirements.
• Integrates well with CI and GitOps pipelines by enabling policy testing and promotion alongside application and platform manifests.
• Improves multi-tenant guardrails by enforcing namespace standards, baseline security requirements, and workload constraints consistently across teams.
• Helps with supply chain controls by restricting registries, constraining image tags, and requiring metadata needed for auditability and traceability.

Kyverno is a strong fit when teams want Kubernetes-native policy authoring and operational simplicity for common governance controls. For complex, cross-resource logic or highly custom evaluation, policy design and testing matter to avoid hard-to-maintain rules and unexpected admission behavior.

Common alternatives include Gatekeeper (OPA), OPA-based admission controllers, and Kubernetes ValidatingAdmissionPolicy. For background on admission control patterns, see Kubernetes admission controllers.

Our experience with Kyverno helped us build practical knowledge, reusable policy patterns, and automation workflows that make Kubernetes governance easier to implement and maintain across different teams and environments. We’ve used Kyverno to move policy enforcement closer to delivery pipelines, reduce configuration drift, and standardize security and compliance controls without slowing down developers.

Some of the things we did include:

This experience helped us accumulate significant knowledge across multiple Kyverno use-cases—from security enforcement to platform automation—and enables us to deliver high-quality Kyverno setups that are maintainable, auditable, and aligned with how teams actually ship workloads on Kubernetes.

Some of the things we can help you do with Kyverno include:

• Assess your current Kubernetes governance posture and deliver a prioritized report of policy gaps, risks, and quick wins.
• Define a Policy-as-Code adoption roadmap with rollout phases, ownership, exception strategy, and measurable compliance outcomes.
• Deploy and standardize Kyverno across clusters with production-ready configuration, RBAC, and upgrade-safe operating procedures.
• Design and implement validate/mutate/generate policies to enforce security guardrails, platform standards, and compliance controls.
• Integrate Kyverno into CI/CD and GitOps workflows to catch risky changes pre-merge and prevent configuration drift in production.
• Improve reliability and cost efficiency by enforcing resource requests/limits, safe defaults, and workload hygiene to reduce waste and instability.
• Implement practical exception handling and policy tuning (scoped waivers, labels, namespaces) to reduce noise without weakening controls.
• Set up observability and reporting for policy outcomes (violations, exceptions, trends) to support audit readiness and faster remediation.
• Troubleshoot admission failures and policy conflicts, improving rule behavior, rollout safety, and developer experience.
• Enable platform and application teams with hands-on training and reusable policy patterns aligned with Kyverno best practices.
