About Kyverno

The Kyverno project provides a comprehensive set of tools to manage the complete Policy-as-Code (PaC) lifecycle for Kubernetes and other cloud native environments

Kyverno policies are declarative YAML resources and no new language is required. Kyverno enables use of familiar tools such as kubectl, git, and kustomize to manage policies. Kyverno supports JMESPath and the Common Expressions Language (CEL) for efficient handling of complex logic.

In Kubernetes environments, Kyverno policies can validate, mutate, generate, and cleanup any Kubernetes resource, including custom resources. To help secure the software supply chain Kyverno policies can verify OCI container image signatures and artifacts. Kyverno policy reports and policy exceptions are also Kubernetes API resources.

The Kyverno CLI can be used to apply and test policies off-cluster e.g., as part of an IaC and CI/CD pipelines.

Kyverno Policy Reporter provides report management with a graphical web-based user interface.

Kyverno JSON allows applying Kyverno policies in non-Kubernetes environments and on any JSON payload.

Kyverno Chainsaw provides declarative end-to-end testing for policies.
