Facts

Purpose: Kyverno is a Kubernetes-native policy engine for defining and enforcing policy as code.github.com · 4 Oct 2026
Policy language: Kyverno supports CEL-based policy types and describes applying Kubernetes-style policies outside Kubernetes as part of its mission.kyverno.io · 4 Oct 2026
Policy actions: Its stable policy types can validate, mutate, generate, and delete resources, and verify container image signatures and attestations.kyverno.io · 4 Oct 2026
CI testing: The Kyverno CLI can test policies in CI pipelines against Kubernetes resource manifests before they are applied to a live cluster.kyverno.io · 4 Oct 2026
Integrations: The documentation describes using Kyverno with Helm, YAML manifests, GitHub Actions, and GitOps tools such as ArgoCD.kyverno.io · 4 Oct 2026
Deployment: Kyverno is installed in a Kubernetes cluster, with Helm recommended for production deployments and YAML manifests also available.kyverno.io · 4 Oct 2026
Availability: A standard installation has a required admission controller and optional background, reports, and cleanup controllers; production installations should use high availability mode.kyverno.io · 4 Oct 2026
