Kyverno vs Monokle

Kyverno is a free, open-source policy engine for defining and enforcing policy as code in Kubernetes. Its stable policy types can validate, mutate, generate or delete resources, and verify container image signatures and attestations. The Kyverno CLI can test policies against Kubernetes resource manifests in CI before they are applied to a live cluster. Documentation describes use with Helm, YAML manifests, GitHub Actions and GitOps tools such as ArgoCD. Kyverno is installed in a Kubernetes cluster; Helm is recommended for production, and YAML manifests are also available. A standard installation requires an admission controller, while background, reports and cleanup controllers are optional. Production installations should use high availability mode. The project supports CEL-based policy types and describes applying Kubernetes-style policies outside Kubernetes as part of its mission. Its webhooks default to fail-closed, so matching requests can fail if the API server cannot reach Kyverno. The project documents Cosign signatures for images and manifests, and lists CLI binaries for Linux, macOS and Windows.

Monokle Desktop is a free IDE for creating, exploring, and validating Kubernetes YAML configurations. It supports template-based resource creation, forms, Kubernetes-aware editing, schemas, and CRDs. Users can compare Git branches or repositories, resources across namespaces and clusters, and local configuration with the state of a running cluster. Real-time validation makes configuration issues visible; custom policies and output from CLI tools can also be checked. Helm charts and Kustomize overlays can be dry-run and previewed before deployment. For cluster inspection, Monokle can show resources, dependencies, Kubernetes events, and pod logs to help with troubleshooting. Listed integrations include Flux, Argo CD, Istio CRDs, Cert-Manager CRDs, Sealed Secrets, CDK8s, Tanka, and KPT. The download page describes it as a manifest creation, validation, and compliance IDE for developers, as well as a cluster inspection and troubleshooting tool for SREs. Monokle Desktop is available for Linux, macOS, and Windows. Kubeshop announced that Monokle Cloud and its accompanying GitHub app would be shut down, while open-source products would continue in their GitHub repositories.
