Kubelet probes are diagnostic tools in Kubernetes for container health monitoring and lifecycle management. While the three probe types - Liveness, Readiness, and Startup - offer essential container health checks through HTTP, TCP, and exec mechanisms, they face significant security challenges including SSRF vulnerabilities and NetworkPolicy complications.
