Backend Implementation: - Create NodeHandler with 10 admin-only endpoints - List all nodes with detailed status and resource info - Get cluster-wide statistics (ready/not ready nodes, aggregate capacity) - Add/remove node labels for pod scheduling affinity - Add/remove node taints for workload isolation - Cordon/uncordon nodes to control scheduling - Drain nodes with graceful pod eviction K8s Client Extensions: - Add GetNode() for fetching individual node details - Add PatchNode() for strategic merge patches - Add UpdateNodeTaints() for taint management - Add CordonNode()/UncordonNode() for scheduling control - Add DrainNode() with graceful pod eviction and DaemonSet filtering API Routes (all require admin role): - GET /admin/nodes - List all cluster nodes - GET /admin/nodes/stats - Get aggregate cluster statistics - GET /admin/nodes/:name - Get specific node details - PUT /admin/nodes/:name/labels - Add node label - DELETE /admin/nodes/:name/labels/:key - Remove node label - POST /admin/nodes/:name/taints - Add node taint - DELETE /admin/nodes/:name/taints/:key - Remove node taint - POST /admin/nodes/:name/cordon - Mark node unschedulable - POST /admin/nodes/:name/uncordon - Mark node schedulable - POST /admin/nodes/:name/drain - Evict all pods from node Features: - Admin-only authentication required for all operations - Comprehensive node metadata (OS, kernel, kubelet version, runtime) - Cloud provider info extraction (region, zone, instance type) - Safe pod eviction during drain (skips DaemonSets and static pods) - Configurable grace period for pod eviction - Detailed error handling and validation Related UI fix: - Fix 404 errors in AdminNodes page by providing graceful fallbacks -
