Kube-No-Trouble is a tool designed to help users proactively identify and address the use of deprecated APIs in their Kubernetes clusters. As Kubernetes evolves, API versions become deprecated, necessitating workload upgrades to maintain compatibility. Kube-No-Trouble facilitates this process by inspecting cluster resources and reporting on any instances of deprecated APIs. It primarily relies on retrieving Kubernetes resources from a configured cluster to perform the analysis.
Kube-No-Trouble offers a straightforward approach to detecting deprecated APIs, supporting various data sources like local manifests, kubectl's last applied configuration, and Helm v3 manifests. Its flexible configuration options allow users to specify cluster context, kubeconfig file, and target Kubernetes version. The tool provides clear and actionable output, making it easy to identify and resolve compatibility issues. It is designed with a focus on ease of use and integration into CI/CD pipelines.
