Container Documentation for Cert-Manager-Startupapicheck

Cert-manager-startupapicheck is a specialized container designed to validate the proper installation and configuration of cert-manager in Kubernetes clusters. It performs startup API checks to ensure cert-manager's API endpoints are functioning correctly and the custom resource definitions (CRDs) are properly installed. This container is essential for maintaining certificate management infrastructure integrity in enterprise Kubernetes environments.

📌 Base Foundation: Security-hardened, minimal base OS designed for enterprise containerized environments from {Registry.Example} Registry.
