Scale to zero nodes for Service Fabric managed clusters

  • Article
  • 08/12/2024

The scale to zero feature allows customers to create clusters that have one or more node types with zero nodes. Customers who have test clusters that do not need nodes on an ongoing basis will benefit from lower cost by scaling down to zero. Also, customers who wish to prep their cluster with all necessary configuration before adding nodes will benefit from scale to zero.

Limitations

  • Scaling to zero only work for secondary node types.

Scale to zero in your ARM template

You can modify the vmInstanceCount property to scale your managed cluster to zero nodes:

{  
  "apiVersion": "2024-06-01-preview",  
  "type": "Microsoft.ServiceFabric/managedclusters/nodetypes",  
  "name": "[concat(parameters('clusterName'), '/', parameters('nodeTypeName'))]",  
  "location": "[parameters('clusterLocation')]",  
  "dependsOn": [  
    "[concat('Microsoft.ServiceFabric/managedclusters/', parameters('clusterName'))]"  
  ],  
  "properties": {  
    "isPrimary": false,  
    "dataDiskSizeGB": "[parameters('dataDiskSizeGB')]",  
    "vmImagePublisher": "[parameters('vmImagePublisher')]",  
    "vmImageOffer": "[parameters('vmImageOffer')]",  
    "vmImageSku": "[parameters('vmImageSku')]",  
    "vmImageVersion": "[parameters('vmImageVersion')]",  
    "vmSize": "[parameters('vmSize')]",  
    "vmInstanceCount": 0  
  }  
}
