问题描述

问题

在使用VSTS幂等连续集成/连续部署过程时，如何将两个不同的Azure App Services部署到同一App Service计划.

How to deploy two different Azure App Services to the same App Service plan when using VSTS idempotent continuous integration / continuous deployment processes.

环境

  • 我写了两个ARM TEMPLATES，每个都将一个Web应用程序部署到Azure App Service.

  • I have written two ARM TEMPLATES each of which deploy a web application to Azure App Service.

要部署App Service，必须首先创建服务计划.

In order to deploy an App Service an Service Plan must be created first.

ARM TEMPLATES当前为每个Web App创建一个唯一的服务计划.

The ARM TEMPLATES currently create a unique Service Plan each for each Web App.

我正在使用VSTS版本定义在每个成功的VSTS构建上进行部署.即发布被设计为幂等的.

I am using VSTS Release Definitions to deploy on each successful VSTS build. i.e releases are designed to be idempotent.

当前，每个Web应用程序都有自己的资源组，其中包括自己的应用程序服务计划.理想情况下，每个Web应用程序都有其自己的资源组，但是应用服务计划可以位于其自己的资源组中(如果可能).

Currently each web app has its own Resource Group which includes it own App Service Plan. Ideally each web app has its own Resource Group, App Service Plan can be in its own Resource Group however (if this is possible).

下面的模板是用于将Web App服务部署到App Service计划的模板之一的示例.

The template below is an example of one of the templates used to deploy the Web App service to an App Service Plan.

它显示了使用命名转换的App Service Plan的创建:

It shows the creation of the App Service Plan using the naming conversion:

appname-Plan-q2dkkaaaaaaaa

这是使用以下方法创建的:

This is created using:

  • 在ARM参数文件中定义的七个字符标识符"appname".
  • 资源标识符计划".
  • 资源组名称，它来自创建时随机命名的存储帐户名称"q2dkkaaaaaaaa".

即

"hostingPlanName": "[concat(parameters('appName'),'-Plan-', uniqueString(resourceGroup().id))]",

问题

我正在尝试执行两个ARM模板(类似于上面的示例)，以将两个不同的Web应用程序部署到同一服务计划.

I am attempting to execute two ARM TEMPLATES (similar to the above example) to deploy two different Web Apps to the same Service Plan.

很明显，这两个Web应用程序都必须调用相同的中央资源，以确保它们都部署到相同的App Service资源名称并执行任何更改.

Its clear that both of these Web Apps must call the same central resource to ensure they both deploy to same App Service resource name and execute any changes.

  • 如果存在App Service计划=部署Web应用.
  • 如果不存在应用服务计划=创建服务计划，则部署Web应用.
  • 如果App Service计划已更改=部署服务计划更改(例如，层更改)，则部署Web应用程序.

考虑到上面的环境描述，我必须采取什么选择措施才能使其正常工作?

Taking the environmental description above into consideration , what options do I have to get this working?

  • 版本定义中的"VSTS全局"参数可能是?
  • ARM模板调用创建应用程序服务计划的PowerShell脚本吗?

热衷于遵循最佳实践.

我希望以上内容能详细描述.抱歉，如果错过了什么.谢谢.

I hope the above is described in enough detail. Sorry if something has been missed. Thank you.

推荐答案

解决方案

我的解决方案是创建三个模板:

The solution in my case was to create three templates:

  • 模板1以创建应用程序服务计划.该ARM模板存储在BLOB容器中，并且可以通过SAS URI访问发布管道.
  • 用于创建Web应用程序A的模板2.此模板使用LINKED TEMPLATE功能来调用和执行共享模板.
  • 用于创建Web应用程序B的模板3.此模板使用链接模板功能来调用和执行共享模板.

结果

  • 然后将这两个Web应用程序发布到同一服务器场，并共享 实例.
  • 保持部署的幂等性.
  • 任何应用程序服务计划部署和任何修订的单一事实.
  • 节省了所需服务器场数量上的钱.
  • Both web apps are then published to the same server farm, sharing the instances.
  • The idempotent nature of the deployment is maintained.
  • Single point of truth for any app service plan deployment and any amendments.
  • Money saved on number of server farms required.

示例

共享服务计划-共享服务计划的ARM模板示例:

Shared Service Plan - ARM Template example of a shared service plan:

{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
    "planLabel": {
        "defaultValue": "shared-service-plan",
        "type": "string"
    }
},
"variables": {
    "servicePlanName": "[concat(parameters('planLabel'),'-Plan-', uniqueString(resourceGroup().id))]"
},
"resources": [
    {
        "comments": "Creates an App Service Plan on the Standard (S1) SKU.",
        "type": "Microsoft.Web/serverfarms",
        "sku": {
            "name": "S1",
            "tier": "Standard",
            "size": "S1",
            "family": "S",
            "capacity": 2
        },
        "kind": "app",
        "name": "[variables('servicePlanName')]",
        "apiVersion": "2016-09-01",
        "location": "[resourceGroup().location]",
        "properties": {
            "name": "[variables('servicePlanName')]"
        },
        "dependsOn": []
    }
],
"outputs": {
    "servicePlanResourceId": {
        "type": "string",
        "value": "[resourceId('Microsoft.Web/serverfarms', variables('servicePlanName'))]"
    },
    "servicePlanName":{
        "type": "string",
        "value": "[variables('servicePlanName')]"
    },
    "resourceGroupName":{
        "type": "string",
        "value": "[resourceGroup().name]"
    }
}
}
