Deploy Service Bus and its entities with ARM

With Azure Resource Manager (ARM) templates you can deploy Azure resources. One of the resources you can deploy is a service bus namespace with entities such as queue and topic. You author an ARM template using JSON format and create expression to construct values for your deployment of a service namespace. The ARM template below shows the JSON for creating a service bus namespace.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "serviceBusNamespaceName": {
      "type": "string",
      "metadata": {
        "description": "Name of the Service Bus namespace"
      }
    },
    "serviceBusSku": {
      "type": "string",
      "allowedValues": [
        "Basic",
        "Standard",
        "Premium"
      ],
      "defaultValue": "Standard",
      "metadata": {
        "description": "The messaging tier for service Bus namespace"
      }
    },
    "location": {
      "type": "string",
      "defaultValue": "[resourceGroup().location]",
      "metadata": {
        "description": "Location for all resources."
      }
    }
  },
  "variables": {
    "defaultSASKeyName": "RootManageSharedAccessKey",
    "defaultAuthRuleResourceId": "[resourceId('Microsoft.ServiceBus/namespaces/authorizationRules', parameters('serviceBusNamespaceName'), variables('defaultSASKeyName'))]",
    "sbVersion": "2017-04-01"
  },
  "resources": [
    {
      "apiVersion": "2017-04-01",
      "name": "[parameters('serviceBusNamespaceName')]",
      "type": "Microsoft.ServiceBus/namespaces",
      "location": "[parameters('location')]",
      "sku": {
        "name": "[parameters('serviceBusSku')]"
      }
    }
  ],
  "outputs": {
    "NamespaceDefaultConnectionString": {
      "type": "string",
      "value": "[listkeys(variables('defaultAuthRuleResourceId'), variables('sbVersion')).primaryConnectionString]"
    },
    "DefaultSharedAccessPolicyPrimaryKey": {
      "type": "string",
      "value": "[listkeys(variables('defaultAuthRuleResourceId'), variables('sbVersion')).primaryKey]"
    }
  }
}

You can apply the template by using PowerShell script in the Cloud Shell. Or you use the Azure Portal using a custom template, CLI, or REST API. Either way it is good practice to deploy resources such as a Service Bus Namespace using ARM templates to keep it consist over various environments (Development, UAT, and production).

Beside deploying just a Service Bus Namespace you could include creation of queues, topics, authorization rule, and subscriptions. The Microsoft Docs provide examples of those ARM templates.
