Creación de temas del sistema en Azure Event Grid con plantillas de Resource Manager

En este artículo se muestra cómo crear y administrar temas del sistema con plantillas de Resource Manager. Para ver un resumen de los temas del sistema, consulte Temas del sistema.

Creación del tema del sistema primero y después la suscripción de eventos

Para crear un tema del sistema en un origen de Azure en primer lugar y después crear una suscripción de eventos para ese tema, puede usar una plantilla como la siguiente:

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "storageName": {
            "type": "string",
            "defaultValue": "[concat('storage', uniqueString(resourceGroup().id))]",
            "metadata": {
                "description": "Provide a unique name for the Blob Storage account."
            }
        },
        "location": {
            "type": "string",
            "defaultValue": "[resourceGroup().location]",
            "metadata": {
                "description": "Provide a location for the Blob Storage account that supports Event Grid."
            }
        },

            "type": "string",
            "defaultValue": "subToStorage",
            "metadata": {
                "description": "Provide a name for the Event Grid subscription."
            }
        },
        "endpoint": {
            "type": "string",
            "metadata": {
                "description": "Provide the URL for the WebHook to receive events. Create your own endpoint for events."
            }
        },
        "systemTopicName": {
            "type": "String",
            "defaultValue": "mystoragesystemtopic",

            },
            "kind": "StorageV2",
            "location": "[parameters('location')]",
            "tags": {},
            "properties": {
                "accessTier": "Hot"
            }
        },
        {

            ],
            "properties": {
                "source": "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageName'))]",
                "topicType": "Microsoft.Storage.StorageAccounts"
            }
        },
        {
            "type": "Microsoft.EventGrid/systemTopics/eventSubscriptions",

            "dependsOn": [

            ],

                        "Microsoft.Storage.BlobDeleted"
                    ]
                }
            }
        }
    ]
}

Creación de un tema del sistema al crear una suscripción de eventos

Para crear un tema del sistema implícitamente, al crear una suscripción de eventos en un origen de Azure, puede usar la siguiente plantilla:

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",

        "storageName": {
            "type": "string",
            "defaultValue": "[concat('storage', uniqueString(resourceGroup().id))]",
            "metadata": {
                "description": "Provide a unique name for the Blob Storage account."
            }
        },
        "location": {
            "type": "string",
            "defaultValue": "[resourceGroup().location]",
            "metadata": {
                "description": "Provide a location for the Blob Storage account that supports Event Grid."
            }
        },

        {
            "type": "Microsoft.Storage/storageAccounts/providers/eventSubscriptions",
            "name": "[concat(parameters('storageName'), '/Microsoft.EventGrid/', parameters('eventSubName'))]",
            "apiVersion": "2018-01-01",
            "dependsOn": [
                "[parameters('storageName')]"
            ],

                },
                "filter": {
                    "subjectBeginsWith": "",

                    "isSubjectCaseSensitive": false,
                    "includedEventTypes": [
                        "All"
                    ]
                }
            }
