如何使用ARM使用托管SSL证书部署App

Question

我希望创建一个具有自定义主机名绑定和托管SSL证书的Azure Azure。

当我创建一个Bicep-模板时，只有当主机名绑定已经创建时，才能部署证书资源。但是要创建主机名绑定，我需要证书拇指指纹。

更新同一模板中的主机名绑定也是不可能的，因为一个资源只能在模板中存在一次。

// hostname bindings must be deployed one by one to prevent Conflict (HTTP 429) errors.
@batchSize(1)
resource customHostnameWithoutSsl 'Microsoft.web/sites/hostnameBindings@2019-08-01' = [for fqdn in customHostnames: {
  name: '${webAppService.name}/${fqdn}'
  properties: {
    siteName: webAppService.name
    hostNameType: 'Verified'
    sslState: 'Disabled'
  }
}]

// Managed certificates can only be created once the hostname is added to the web app.
resource certificates 'Microsoft.Web/certificates@2022-03-01' = [for (fqdn, i) in customHostnames: {
  name: '${fqdn}-${webAppName}'
  location: location
  properties: {
    serverFarmId: appServicePlanResourceId
    canonicalName: fqdn
  }
  dependsOn: [ ]
}]

// sslState and thumbprint can only be set once the managed certificate is created
@batchSize(1)
resource customHostname 'Microsoft.web/sites/hostnameBindings@2019-08-01' = [for (fqdn, i) in customHostnames: {
  name: '${webAppService.name}/${fqdn}'
  properties: {
    siteName: webAppService.name
    hostNameType: 'Verified'
    sslState: 'SniEnabled'
    thumbprint: certificates[i].properties.thumbprint
  }
}]

是否有另一种方法来创建一个单独的部署模板来为自定义主机名部署带有托管SSL证书的Azure Azure？

Answer 1

更新同一个模板中的主机名绑定也是不可能的，因为一个资源只能在模板中存在一次。

为了防止此错误，可以使用Bicep模块(或ARM嵌套模板)部署资源。

然后解决办法是：

webApp.bicep

@description('The name of the App Service Plan that this web app will be deployed to.')
param appServicePlanResourceId string

@description('The location that the resource will be deployed to')
param location string = resourceGroup().location

@description('The custom hostnames that you wish to add.')
param customHostnames array = []

@description('Deploy hostnames without SSL binding before creating the certificate. Required when hostname is not present yet.')
param redeployHostnames bool = false

resource webAppService 'Microsoft.Web/sites@2020-12-01' = {
  ...
}

// hostname bindings must be deployed one by one to prevent Conflict (HTTP 429) errors.
@batchSize(1)
resource customHostnameWithoutSsl 'Microsoft.web/sites/hostnameBindings@2019-08-01' = [for fqdn in customHostnames: if (redeployHostnames) {
  name: '${webAppService.name}/${fqdn}'
  properties: {
    siteName: webAppService.name
    hostNameType: 'Verified'
    sslState: 'Disabled'
  }
}]

// certificates must be bound via module/nested template, because each resource can only occur once in every template
// in this case the hostnameBindings would occur twice otherwise.
module certificateBindings './bindCertificateToHostname.bicep' = {
  name: '${deployment().name}-ssl'
  params: {
    appServicePlanResourceId: appServicePlanResourceId
    customHostnames: customHostnames
    location: location
    webAppName: webAppService.name
  }
  dependsOn: customHostnameWithoutSsl
}

bindCertificateToHostname.bicep

param webAppName string
param location string
param appServicePlanResourceId string
param customHostnames array

// Managed certificates can only be created once the hostname is added to the web app.
resource certificates 'Microsoft.Web/certificates@2022-03-01' = [for (fqdn, i) in customHostnames: {
  name: '${fqdn}-${webAppName}'
  location: location
  properties: {
    serverFarmId: appServicePlanResourceId
    canonicalName: fqdn
  }
}]

// sslState and thumbprint can only be set once the managed certificate is created
@batchSize(1)
resource customHostname 'Microsoft.web/sites/hostnameBindings@2019-08-01' = [for (fqdn, i) in customHostnames: {
  name: '${webAppName}/${fqdn}'
  properties: {
    siteName: webAppName
    hostNameType: 'Verified'
    sslState: 'SniEnabled'
    thumbprint: certificates[i].properties.thumbprint
  }
}]

其中一个解决办法，您可以遵循，以实现上述要求；

要为自定义域部署带有SSL证书的应用程序服务，您可以遵循@bmoore在此上建议的完整配置和模板：-

样本template.json:-

"resources": [
    {
        "type": "Microsoft.Web/serverfarms",
        "apiVersion": "2019-08-01",

        "location": "[parameters('location')]",
        "properties": {
            "name": "[variables('appServicePlanName')]"
        },

        "location": "[parameters('location')]",
        "dependsOn": [

        ],

            "serverFarmId": "[resourceId('Microsoft.Web/serverFarms', variables('appServicePlanName'))]"
        }
    },
    {
        "type": "Microsoft.Web/sites/hostnameBindings",
        "name": "[concat(parameters('webAppName'), '/', parameters('customHostname'))]",
        "apiVersion": "2019-08-01",
        "location": "[parameters('location')]",
        "dependsOn": [
            "[resourceId('Microsoft.Web/certificates', variables('certificateName'))]"
        ],
        "properties": {
            "sslState": "[if(variables('enableSSL'), 'SniEnabled', json('null'))]",
            "thumbprint": "[if(variables('enableSSL'), reference(resourceId('Microsoft.Web/certificates', variables('certificateName'))).Thumbprint, json('null'))]"
        }
    }

注意：-我无法用自定义域测试它，因为我们的帐户有一些条款问题。
