Validate your Kubernetes configuration

Sonobuoy is a diagnostic tool that makes it easier to understand the state of a Kubernetes cluster by running a choice of configuration tests in an accessible and non-destructive manner.

Conformance Testing

Ensure that a cluster is properly configured and that its behavior conforms to official Kubernetes specifications.

Workload Debugging

Easily generate diagnostics for troublesome workloads that are difficult to debug.

Custom Tests and Data Collection

Create plug-ins to test any custom configuration or use a variety of community plug-ins.
