I am looking to create an ARM template code to be able to deploy several VMs with different names using copy and copyindex. To achieve this, I turned to this Microsoft procedure:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"storageNames": {
"type": "array",
"defaultValue": [
"contoso",
"fabrikam",
"coho"
]
}
},
"resources": [
{
"type": "Microsoft.Storage/storageAccounts",
"apiVersion": "2019-04-01",
"name": "[concat(parameters('storageNames')[copyIndex()], uniqueString(resourceGroup().id))]",
"location": "[resourceGroup().location]",
"sku": {
"name": "Standard_LRS"
},
"kind": "Storage",
"properties": {},
"copy": {
"name": "storagecopy",
"count": "[length(parameters('storageNames'))]"
}
}
],
"outputs": {}
}
But I have problem when I use array with concat and variables too. it gives me several errors. Can you help me make this code? I would like to use the minimum parameter.
here are my 2 different templates:

Here are the errors encountered:
InvalidTemplate - Deployment template validation failed: 'The template variable 'NSGName' is not valid: The template function 'copyIndex' is not expected at this location. The function can only be used in a resource with copy
specified. Please see https://aka.ms/arm-copy for usage details.. Please see https://aka.ms/arm-template-expressions for usage details.'.
InvalidTemplate - Deployment template validation failed: 'The template resource '[concat(parameters('VMNames'), '-pip01')]' at line '24' and column '9' is not valid: The provided parameters for language function 'concat' are
invalid. Either all or none of the parameters must be an array. Please see https://aka.ms/arm-template-expressions/#concat for usage details.. Please see https://aka.ms/arm-template-expressions for usage details.'.
CodePudding user response：
It seem that you might be missing iteration property in resource deployment: add "copy" property.
{
"name": "[concat(parameters('VMNames')[copyIndex()].name, '-nsg01')]",
"type": "Microsoft.Network/networkSecurityGroups",
"apiVersion": "2020-11-01",
"location": "[parameters('Location')]",
"properties": {
"securityRules": [
{
"name": "nsgRule1",
"properties": {
"description": "description",
"protocol": "Tcp",
"sourcePortRange": "*",
"destinationPortRange": "3389",
"sourceAddressPrefix": "*",
"destinationAddressPrefix": "*",
"access": "Allow",
"priority": 100,
"direction": "Inbound"
}
}
]
},
"copy": {
"name": "VMcopy",
"count": "[length(parameters('VMNames'))]"
}
}
In this case you don't need to iterate in variable

Thank you for your answer Greg, I just did what you told me but there is still an error:
