Kubernetes controller lifecycle validation analyzes leader election and graceful shutdown configurations to ensure high availability and minimize downtime. It verifies signal handling and manager setup using gopls for Go-based controller-runtime projects.

Webhook certificate provisioning validation checks your admission webhook manifests and certificate setup to ensure controllers are properly secured. It analyzes cert provisioning configurations in Go-based kubebuilder projects to prevent misconfigured webhooks.

CRD upgrade safety checks validate multi-version serving and conversion strategies in your CRD manifests. The analyzer inspects these configurations to ensure Kubernetes controller upgrades proceed safely without serving conflicts or schema drift.

Yes, the lifecycle analyzer works with Go-based controllers built using controller-runtime and kubebuilder patterns across both GitHub repositories and on-prem deployments. It validates manager config, deployment manifests, and webhook manifests regardless of hosting environment.

Controller leadership loss during rolling updates often stems from misconfigured leader election or improper signal handling in graceful shutdown. The lifecycle analyzer verifies these mechanisms using gopls to detect configuration gaps causing downtime.

Yes, this lifecycle assessment targets Go-based controllers built with controller-runtime and kubebuilder patterns. It validates manager config, deployment manifests, and webhook manifests specific to that framework ecosystem.
