Sonobuoy Docs

Sonobuoy is a diagnostic tool that makes it easier to understand the state of a Kubernetes cluster by running a set of plugins (including Kubernetes conformance tests) in an accessible and non-destructive manner. It is a customizable, extendable, and cluster-agnostic way to generate clear, informative reports about your cluster.

Its selective data dumps of Kubernetes resource objects and cluster nodes allow for the following use cases:

  • Integrated end-to-end (e2e) conformance-testing
  • Workload debugging
  • Custom data collection via extensible plugins

Sonobuoy supports 3 Kubernetes minor versions: the current release and 2 minor versions before. Sonobuoy is currently versioned to track the Kubernetes minor version to clarify the support matrix. For example, Sonobuoy v0.14.x would support Kubernetes 1.14.x, 1.13.x, and 1.12.x.

Note: You can skip this version enforcement by running Sonobuoy with the --skip-preflight flag.
