Kubernetes Node Pool Management and Cloud-Specific Scaling Patterns
Node Pool Design Patterns GKE Node Pool Configuration # GKE Node Pool resource "google_container_node_pool" "general_purpose" { name = "general-purpose" cluster = google_container_cluster.primary.name location = "us-central1" autoscaling { min_node_count = 1 max_node_count = 10 location_policy = "BALANCED" } node_config { machine_type = "n2-standard-4" disk_size_gb = 100 disk_type = "pd-ssd" labels = { role = "general" env = "production" } taint { key = "specialty" value = "gpu" effect = "NO_SCHEDULE" } } management { auto_repair = true auto_upgrade = true } } EKS Node Group Configuration # EKS Node Group resource "aws_eks_node_group" "compute_optimized" { cluster_name = aws_eks_cluster.main.name node_group_name = "compute-optimized" node_role_arn = aws_iam_role.eks_node.arn subnet_ids = aws_subnet.private[*].id scaling_config { desired_size = 2 max_size = 10 min_size = 1 } instance_types = ["c5.2xlarge"] capacity_type = "SPOT" labels = { workload = "compute" cost = "spot" } taint { key = "workload" value = "compute" effect = "NO_SCHEDULE" } } AKS Node Pool Configuration # AKS Node Pool resource "azurerm_kubernetes_cluster_node_pool" "memory_optimized" { name = "memopt" kubernetes_cluster_id = azurerm_kubernetes_cluster.main.id vm_size = "Standard_E4s_v3" enable_auto_scaling = true min_count = 1 max_count = 5 node_labels = { workload = "memory-intensive" } node_taints = [ "workload=memory:NoSchedule" ] zones = [1, 2, 3] } Cloud-Specific Features GKE-Specific Capabilities # GKE-specific features resource "google_container_cluster" "advanced" { # Autopilot mode enable_autopilot = true # Vertical Pod Autoscaling vertical_pod_autoscaling { enabled = true } # Binary Authorization enable_binary_authorization = true # Workload Identity workload_identity_config { workload_pool = "${project_id}.svc.id.goog" } } EKS-Specific Features # EKS-specific features resource "aws_eks_cluster" "advanced" { # Fargate Profiles fargate_profile { name = "serverless" selectors { namespace = "serverless" } } # IPv6 Support kubernetes_network_config { ip_family = "ipv6" } # Secrets Encryption encryption_config { provider { key_arn = aws_kms_key.eks.arn } resources = ["secrets"] } } AKS-Specific Features # AKS-specific features resource "azurerm_kubernetes_cluster" "advanced" { # Azure CNI Overlay network_profile { network_plugin = "azure" network_policy = "calico" network_mode = "overlay" } # Azure AD Integration azure_active_directory_role_based_access_control { managed = true azure_rbac_enabled = true } # Azure Key Vault Integration key_vault_secrets_provider { secret_rotation_enabled = true } }
