使用Terraform为AzureFunction创建AzureFunction

Question

我正在尝试使用Terraform部署Azure函数基础设施和HttpTrigger。我知道，使用Terraform，我将创建基础设施，触发部分是代码责任。，但仍然不知道如何创建HttpTrigger。你能告诉我吗？

terraform {
  required_providers {
    azurerm = {
      source = "hashicorp/azurerm"
      version = "~> 2.26"
    }
  }
}

  location            = var.location
  kind                = "FunctionApp"
  reserved = true
  sku {
    tier = "Dynamic"
    size = "Y1"
  }

###############################
# Function

}
resource "azurerm_storage_container" "storage_container" {

  permissions {
    read   = true
    add    = false
    create = false
    write  = false
    delete = false
    list   = false

带有python代码的函数-app文件夹有两个文件：1. init.py

import logging
import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

    if name:
        return func.HttpResponse(f"Hello {name}!")
    else:
        return func.HttpResponse(
            "Please pass a name on the query string or in the request body",
            status_code=400
        )

2. function.json

   {
      "scriptFile": "__init__.py",
      "bindings": [
        {
          "authLevel": "function",
          "type": "httpTrigger",
          "direction": "in",
          "name": "req",
          "methods": [
            "get",
            "post"
          ]
        },
        {
          "type": "http",
          "direction": "out",
          "name": "$return"
        }
      ]
    }

通过Azure管道成功完成部署过程。在Azure门户上，当我试图打开AzureFunction ->函数时，看不到任何东西。

但是，在App中，我确实看到了以前创建的python函数文件

Answer 1

使用terraform创建HTTP触发器函数应用程序。

1. 使用以下方法创建示例HTTP触发器函数

• 作为类型记录的功能项目
• 作为HTTP触发器的功能
• 功能名称:您自己的
• 授权级别:匿名

1. 添加下面的Terraform文件

• 资源组
• 存储帐户
• 应用洞察
• 服务计划

3.下面是在terraform模块文件夹中输入的示例代码，以获取蔚蓝功能资源。

variable "LOCATION" {}

variable "RESOURCE_GROUP" {}

variable "STORAGE_ACC_NAME" {}

variable "STORAGE_ACC_KEY" {}

variable "STORAGE_CONNECTION_STRING" {}

resource "azurerm_application_insights" "func_application_insights" {

name = "func-application-insights"

location = var.LOCATION

resource_group_name = var.RESOURCE_GROUP

application_type = "Node.JS"

}

resource "azurerm_app_service_plan" "func_app_service_plan" {

name = "func-app-service-plan"

location = var.LOCATION

resource_group_name = var.RESOURCE_GROUP

kind = "FunctionApp"

reserved = true

sku {

tier = "Dynamic"

size = "Y1"

}

}

resource "azurerm_function_app" "func_function_app" {

name = "func-function-app"

location = var.LOCATION

resource_group_name = var.RESOURCE_GROUP

app_service_plan_id = azurerm_app_service_plan.func_app_service_plan.id

app_settings = {

FUNCTIONS_WORKER_RUNTIME = "node",

AzureWebJobsStorage = var.STORAGE_CONNECTION_STRING,

APPINSIGHTS_INSTRUMENTATIONKEY = azurerm_application_insights.func_application_insights.instrumentation_key,

WEBSITE_RUN_FROM_PACKAGE = "1"

}

os_type = "linux"

storage_account_name = var.STORAGE_ACC_NAME

storage_account_access_key = var.STORAGE_ACC_KEY

version = "~3"

lifecycle {

ignore_changes = [

app_settings["WEBSITE_RUN_FROM_PACKAGE"]

]

}

# FIXME: Use DNS names instead of enabling CORS

site_config {

cors {

allowed_origins = ["*"]

}

}

}
