Azure Cluster Listing

List all AKS and ARO clusters in your Azure subscription with detailed information.

Task Workflow

Phase 1: Authentication Check

1. Verify Azure CLI authentication:

   az account show --output json
   

   • Extract and display subscription ID and name
   • If not authenticated, instruct user to run az login

Phase 2: List Clusters

List AKS Clusters

If --type is "aks" or "all":

az aks list \
  ${RESOURCE_GROUP:+--resource-group $RESOURCE_GROUP} \
  --output json

Extract for each AKS cluster:

• Name
• Resource Group
• Location
• Kubernetes Version
• Node Count
• Provisioning State
• FQDN
• Power State

List ARO Clusters

If --type is "aro" or "all":

az aro list \
  ${RESOURCE_GROUP:+--resource-group $RESOURCE_GROUP} \
  --output json

Extract for each ARO cluster:

• Name
• Resource Group
• Location
• OpenShift Version
• Provisioning State
• Console URL
• API Server URL

Phase 3: Format and Display

Table Format (Default)

Azure Clusters in Subscription: <subscription-name> (<subscription-id>)

AKS CLUSTERS:
┌─────────────────┬─────────────────┬──────────┬─────────┬───────┬──────────┐
│ Name            │ Resource Group  │ Location │ Version │ Nodes │ State    │
├─────────────────┼─────────────────┼──────────┼─────────┼───────┼──────────┤
│ prod-aks-001    │ production-rg   │ eastus   │ 1.28.9  │ 5     │ Succeeded│
│ dev-aks-001     │ development-rg  │ westus2  │ 1.28.5  │ 3     │ Succeeded│
└─────────────────┴─────────────────┴──────────┴─────────┴───────┴──────────┘

ARO CLUSTERS:
┌─────────────────┬─────────────────┬──────────┬─────────┬──────────┐
│ Name            │ Resource Group  │ Location │ Version │ State    │
├─────────────────┼─────────────────┼──────────┼─────────┼──────────┤
│ prod-aro-001    │ production-rg   │ eastus2  │ 4.15.0  │ Succeeded│
└─────────────────┴─────────────────┴──────────┴─────────┴──────────┘

Total: 3 clusters (2 AKS, 1 ARO)

Quick Connect:
  cluster-code connect azure --name prod-aks-001 --resource-group production-rg
  cluster-code connect azure --name prod-aro-001 --resource-group production-rg

JSON Format

If --format json, output structured JSON:

{
  "subscription": {
    "id": "...",
    "name": "..."
  },
  "clusters": {
    "aks": [
      {
        "name": "prod-aks-001",
        "resourceGroup": "production-rg",
        "location": "eastus",
        "kubernetesVersion": "1.28.9",
        "nodeCount": 5,
        "provisioningState": "Succeeded",
        "fqdn": "prod-aks-001-dns-12345678.hcp.eastus.azmk8s.io",
        "powerState": "Running"
      }
    ],
    "aro": [
      {
        "name": "prod-aro-001",
        "resourceGroup": "production-rg",
        "location": "eastus2",
        "openshiftVersion": "4.15.0",
        "provisioningState": "Succeeded",
        "consoleUrl": "https://console-openshift-console.apps.prod-aro-001.example.com",
        "apiServerUrl": "https://api.prod-aro-001.example.com:6443"
      }
    ]
  },
  "summary": {
    "total": 3,
    "aks": 2,
    "aro": 1,
    "running": 3,
    "stopped": 0
  }
}

Phase 4: Additional Information

For each cluster, optionally show:

1. Cost Estimate (if requested):

   az consumption usage list \
     --start-date $(date -d '30 days ago' +%Y-%m-%d) \
     --end-date $(date +%Y-%m-%d) \
     | grep <cluster-name>
   

2. Node Pool Details (AKS):

   az aks nodepool list \
     --resource-group <resource-group> \
     --cluster-name <cluster-name>
   

3. Add-ons Status (AKS):

   az aks addon list \
     --resource-group <resource-group> \
     --name <cluster-name>
   

Error Handling

1. No clusters found:

   ℹ️  No clusters found in subscription.
   
   Create a new cluster:
     cluster-code azure-cluster-create --type aks --name my-cluster --resource-group my-rg
   

2. Authentication error:

   ⚠️  Not authenticated to Azure.
   
   Run: az login
   

3. Insufficient permissions:

   ⚠️  Insufficient permissions to list clusters.
   
   Required role: Reader or higher on subscription/resource group
   

Output Guidelines

• Use colored output for better readability (green for running, yellow for provisioning, red for failed)
• Show cluster age (created timestamp)
• Highlight clusters with issues or warnings
• Provide quick connect commands
• Show estimated monthly cost if available
