Pluto is a Go command-line utility from Fairwinds that detects deprecated and removed Kubernetes apiVersions in static manifests, Helm charts, and live Helm 2/3 releases. It flags whether an apiVersion is merely DEPRECATED or fully REMOVED so teams can fix manifests before a cluster upgrade breaks their workloads.
Use cases
- find deprecated kubernetes apiVersions in my yaml manifests
- check helm charts for removed api versions before a cluster upgrade
- scan live helm releases in my cluster for deprecated apis
- verify no deprecated kubernetes APIs before upgrading the cluster
- add a CI check that fails on deprecated kubernetes apiVersions
- detect old apps/v1beta1 or extensions/v1beta1 usage in my IaC repo
When to choose
- You are preparing a Kubernetes version upgrade and need to locate every deprecated or removed apiVersion
- You want to audit infrastructure-as-code repos containing static manifests and Helm charts
- You need to inspect running Helm 2 or Helm 3 releases in a cluster without relying on the api-server's version conversion
- You want a lightweight CLI or GitHub Action gate in CI for apiVersion deprecation
When to avoid
- You need general Kubernetes security, policy, or best-practice auditing rather than apiVersion deprecation (tools like Polaris or kube-linter fit better)
- You need full-fledged manifest linting or schema validation beyond apiVersion checks
- Your project does not use Kubernetes or Helm at all
