Kubernetes object metrics collection for the goldentooth cluster.

This repository contains the Kubernetes manifests for deploying kube-state-metrics, which exposes metrics about Kubernetes objects (pods, deployments, services, etc.) to Prometheus.

• Namespace: kube-state-metrics
• Service Account: With cluster-wide read permissions for Kubernetes objects
• ClusterRole: Comprehensive permissions to list and watch all relevant Kubernetes resources
• Deployment: Single replica deployment of kube-state-metrics v2.13.0
• Service: ClusterIP service exposing metrics on port 8080

kube-state-metrics provides metrics for:

• Pods, Deployments, ReplicaSets, StatefulSets, DaemonSets
• Services, Endpoints, Ingresses
• ConfigMaps, Secrets, PersistentVolumes, PersistentVolumeClaims
• Nodes, Namespaces, Jobs, CronJobs
• HorizontalPodAutoscalers, PodDisruptionBudgets
• NetworkPolicies, StorageClasses, VolumeAttachments
• And many more Kubernetes objects

This repository is automatically deployed via Argo CD using the gitops-repo ApplicationSet. The deployment:

• Creates the kube-state-metrics namespace
• Deploys kube-state-metrics with proper RBAC permissions
• Exposes metrics for Prometheus scraping
• Uses security best practices (non-root user, read-only filesystem, dropped capabilities)

The service includes Prometheus annotations for automatic discovery:

annotations:
  prometheus.io/scrape: 'true'
  prometheus.io/port: '8080'
  prometheus.io/path: '/metrics'

This enables Prometheus to automatically scrape Kubernetes object metrics from the cluster.
