Sonobuoy is a Go CLI diagnostic tool that runs Kubernetes conformance tests and custom plugins against a cluster to generate informative, non-destructive reports. It is the underlying technology for CNCF Certified Kubernetes conformance certification and supports extensible plugins for custom data collection.
Use cases
- run kubernetes conformance tests on my cluster
- certify my kubernetes distribution for CNCF conformance
- generate a diagnostic report of my kubernetes cluster state
- debug a troublesome workload in kubernetes
- collect custom data from cluster nodes via plugins
- run e2e tests on an air-gapped kubernetes cluster
When to choose
- you need to validate a cluster conforms to official Kubernetes specifications
- you want non-destructive diagnostics and selective resource dumps from a cluster
- you need CNCF conformance certification results
- you run clusters in air-gapped environments with private registries
When to avoid
- you need continuous runtime monitoring or alerting rather than on-demand diagnostics
- you want application-level testing rather than cluster-level conformance
- you need a GUI dashboard for cluster observability
