[Cluster API](https://cluster-api.sigs.k8s.io/) is the Kubernetes sub-project for declarative cluster lifecycle management. Used by platform teams to provision and manage workload clusters. ### What Radar Shows **Topology:** Full CAPI ownership chain - ClusterClass → Cluster → KubeadmControlPlane → Machine → Node, and Cluster → MachineDeployment → MachineSet → Machine → Node. MachineHealthCheck → Cluster protection edges. Machine → Node edges use status.nodeRef (semantic, not owner-ref). **Cluster Detail View:** * Phase, version, cluster class, control plane endpoint * Control plane and worker replica counts (v1beta2-aware) * Control plane and infrastructure references (clickable) * ClusterClass topology section (worker MachineDeployments table) * "Connect to Cluster" button - auto-connects Radar to the workload cluster * "Download Kubeconfig" button * Conditions **Machine Detail View:** * Phase, role (Control Plane / Worker), version, provider ID * Clickable Node reference (via status.nodeRef) * Addresses table, node info (OS, architecture, kernel, kubelet) * Bootstrap and infrastructure references **MachineDeployment Detail View:** * Phase, replicas (desired/ready/available/up-to-date), strategy * Version, cluster name * Machine template references * Owned machines label hint (copyable) **KubeadmControlPlane Detail View:** * Replicas, version, initialized status (v1beta2-aware) * Machine template with drain/volume detach/deletion timeouts * Kubeadm config highlights (cert SANs) * Last remediation info * Owned machines label hint **ClusterClass Detail View:** * Infrastructure, control plane, worker topology tables * Variables with schema types * Patches with definitions and enabledIf expressions **MachineHealthCheck Detail View:** * Expected/healthy machine counts, remediations allowed * Label selector display * Unhealthy conditions tables (v1beta1 + v1beta2 formats) * Remediation template **Additional renderers:** MachineSet, MachinePool, MachineDrainRule, KubeadmConfig/Template **Resource Browser:** Smart columns for all CAPI kinds - phase badges, replica counts, cluster names, roles, versions. **Topology-controlled badge:** Resources managed by ClusterClass (label `topology.cluster.x-k8s.io/owned`) show a warning banner. **Fleet topology mode:** Dedicated "Fleet" view filters to CAPI and infrastructure provider resources only, giving a clean cluster-management view without application workload noise. Groups start expanded by default. CAPI Fleet Topology - 5 GKE clusters with MachineDeployments, MachinePools, and provider resources **Resource browser** with smart columns per CAPI kind - Provider detection, phase badges, replica counts: CAPI Cluster list with Provider column **Cluster detail view** with Connect to Cluster and Download Kubeconfig actions, provider detection, and clickable references to infrastructure resources: Cluster detail with Connect button and provider references ### Infrastructure Provider Renderers Radar has first-class renderers for **AWS (CAPA)**, **GCP (CAPG)**, and **Azure (CAPZ)** infrastructure provider resources. These surface provider-specific operational data - instance types, scaling config, VPC/subnet topology, managed service addons - that would otherwise be buried in raw YAML. **AWS EKS control plane** - VPC topology with subnets (Public/Private badges), security groups, EKS addons, IAM roles: AWSManagedControlPlane with VPC, subnets, and IAM details **GCP GKE control plane** - project, location, release channel, and conditions timeline with left-aligned timestamps: GCPManagedControlPlane with conditions timeline **Managed machine pools**: Instance/VM types, scaling config (autoscaling min/max), capacity type badges (On-Demand/Spot), node management (auto-repair/upgrade), labels and taints. **Azure AKS**: Location, resource group, SKU tier, network plugin/policy, System/User mode badges, Regular/Spot priority, availability zones. **Individual machines**: Instance type/state badges, provider IDs, addresses, conditions. **Templates and cluster stubs**: Lightweight renderers for instance templates (with resolved capacity) and cluster infrastructure stubs (endpoint + failure domains). ### Supported CRDs | CRD | Group | Topology | Detail View | AI Summary | | --------------------------- | --------------------------------- | -------- | ----------- | ---------- | | Cluster | `cluster.x-k8s.io` | Yes | Yes | Yes | | ClusterClass | `cluster.x-k8s.io` | Yes | Yes | Yes | | Machine | `cluster.x-k8s.io` | Yes | Yes | Yes | | MachineSet | `cluster.x-k8s.io` | Yes | Yes | Yes | | MachineDeployment | `cluster.x-k8s.io` | Yes | Yes | Yes | | MachinePool | `cluster.x-k8s.io` | Yes | Yes | Yes | | MachineHealthCheck | `cluster.x-k8s.io` | Yes | Yes | Yes | | MachineDrainRule | `cluster.x-k8s.io` | No | Yes | No | | KubeadmControlPlane | `controlplane.cluster.x-k8s.io` | Yes | Yes | Yes | | KubeadmControlPlaneTemplate | `controlplane.cluster.x-k8s.io` | No | Generic | No | | KubeadmConfig | `bootstrap.cluster.x-k8s.io` | No | Yes | No | | KubeadmConfigTemplate | `bootstrap.cluster.x-k8s.io` | No | Generic | No | | AWSManagedControlPlane | `controlplane.cluster.x-k8s.io` | Yes | Yes | No | | AWSManagedMachinePool | `infrastructure.cluster.x-k8s.io` | Yes | Yes | No | | AWSMachine | `infrastructure.cluster.x-k8s.io` | Yes | Yes | No | | AWSMachineTemplate | `infrastructure.cluster.x-k8s.io` | No | Yes | No | | AWSManagedCluster | `infrastructure.cluster.x-k8s.io` | No | Yes | No |
