Sonobuoy
Sonobuoy is a free, open-source diagnostic tool for examining Kubernetes cluster state with non-destructive configuration tests. It can check a cluster against official Kubernetes specifications and produce diagnostics for troublesome workloads. Teams can build plugins for additional tests and data collection. Its default plugins run Kubernetes end-to-end tests and gather systemd logs; community options include CIS Benchmarks, Kube-hunter, Who-can, Cluster-Inventory, and Reliability Scanner. It is cluster agnostic and officially supports the latest three minor Kubernetes versions. Beginning with version 0.20, it supports Kubernetes 1.17 or later. Sonobuoy can run end-to-end tests with custom registries in air-gapped deployments. It requires an active Kubernetes cluster and an admin kubeconfig, and can be installed from binary releases or through Homebrew on macOS. The project provides community support through GitHub. Its documentation warns that default settings need explicit hardening, and notes that some logging and retrieval commands can fail on Docker Desktop Kubernetes.
