Deploy multiple containers in the storage account via ARM Template

Question

Is it possible to deploy multiple (2) containers in the storage account via ARM Template?

"resources": [
    {
      "type": "Microsoft.Storage/storageAccounts",
      "name": "",
      "apiVersion": "",      
      "location": "",
      "kind": "",
      "sku": {
        "name": ""
      },      
      "resources": [
        {
            "name": "[concat('default/', parameters('containerName'))]",
            "type": "blobServices/containers"
        }
      ]
    }
  ]

Answer 1

you probably want to trade that simplistic approach to something more manageable:

"variables": [
    "blobs": [
        "myfirstblob",
        "myotherblob"
    ]
],
"resources": [
    {
      "type": "Microsoft.Storage/storageAccounts",
      "name": "",
      "apiVersion": "",      
      "location": "",
      "kind": "",
      "sku": {
        "name": ""
      },      
      "resources": [
        {
            "name": "[concat('default/', variables('blobs')[copyIndex()])]",
            "type": "blobServices/containers",
            "apiVersion": "",
            "copy": {
                "name": "blobIterator",
                "count": "[length(variables('blobs'))]"
            }
        }
      ]
    }
  ]

Answer 2

Yes, you can.

For example, you could use the template below to create a storage account with two containers named container1 and container2.

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "storageAccounts_joy12_name": {
            "type": "String"
        }
    },
    "variables": {},
    "resources": [
        {
            "type": "Microsoft.Storage/storageAccounts",
            "apiVersion": "2019-06-01",
            "name": "[parameters('storageAccounts_joy12_name')]",
            "location": "eastus",
            "sku": {
                "name": "Standard_RAGRS",
                "tier": "Standard"
            },
