通過ARM/msdeploy部署到Azure Web App而不刪除現有文件

Question

使用常規msdeploy（又名WebDeploy，用於Visual Studio或VSTS發佈）部署到Azure Web App（又名Azure App Service）時，可以選擇不是刪除目標上的現有文件。

但是，當使用ARM提供程序（例如，通過ARM模板）時，默認情況下始終刪除現有文件。有沒有辦法來覆蓋這個，而不是吹走現有的文件？

Answer 1

Azure Web App支持DoNotDeleteRule的方式是通過addOnPackages架構元素。

addOnPackages隱式使用DoNotDelete規則。因此，如果您想要在不刪除現有站點中的文件的情況下應用程序包，請在addOnPackages數組中指定它，然後不會在中定義外部MSDeploy對象中的任何內容。例如： -

{ 
    "properties": { 
     "parameters": { 
      "appName": { 
       "value": "mysite" 
      }, 
      "location":{ 
       "value": "USAAnywhere" 
      } 
     }, 
     "template": { 
      "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#", 
      "contentVersion": "1.0.0-r188+188.764a8a7798ecc6ebb752343c6f8e6be2903ba711", 
      "parameters": { 
       "appName": { 
        "type": "string" 
       }, 
       "location": { 
        "type": "string" 
       } 
      }, 
      "resources": [ 
       { 
        "apiVersion": "2016-08-01", 
        "name": "[parameters('appName')]", 
        "location": "[parameters('location')]", 
        "type": "Microsoft.Web/sites", 
        "resources": [ 
         { 
          "apiVersion": "2016-08-01", 
          "name": "MSDeploy", 
          "type": "Extensions", 
          "dependsOn": [ 
           "[concat('Microsoft.Web/Sites/', parameters('appName'))]" 
          ], 
          "properties": { 
           "addOnPackages" : [ 
            { 
             "packageUri": "https://mystorageblob.blob.core.windows.net/package/my_webdeploy_package.zip", 
             "AppOffline": true, 
             "setParameters": { 
              "IIS Web Application Name": "[parameters('appName')]", 
             } 
            } 
           ] 
          } 
         } 
        ], 
        "properties" : {} 
       } 
      ] 
     }, 
     "mode": "Incremental" 
    } 
} 

的addOnPackages還允許在單一MSDeploy ARM模板多個包;外部的將刪除現有網站的文件，並且addOnPackages是附加的，並且不會刪除外部包。例如：

{ 
    "properties": { 
     "parameters": { 
      "appName": { 
       "value": "mysite" 
      }, 
      "location":{ 
       "value": "USAAnywhere" 
      } 
     }, 
     "template": { 
      "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#", 
      "contentVersion": "1.0.0-r188+188.764a8a7798ecc6ebb752343c6f8e6be2903ba711", 
      "parameters": { 
       "appName": { 
        "type": "string" 
       }, 
       "location": { 
        "type": "string" 
       } 
      }, 
      "resources": [ 
       { 
        "apiVersion": "2016-08-01", 
        "name": "[parameters('appName')]", 
        "location": "[parameters('location')]", 
        "type": "Microsoft.Web/sites", 
        "resources": [ 
         { 
          "apiVersion": "2016-08-01", 
          "name": "MSDeploy", 
          "type": "Extensions", 
          "dependsOn": [ 
           "[concat('Microsoft.Web/Sites/', parameters('appName'))]" 
          ], 
          "properties": { 
           "packageUri": "https://mystorageblob.blob.core.windows.net/package/my_webdeploy_package.zip", 
           "dbType": "None", 
           "connectionString": "", 
           "AppOffline": true, 
           "SkipAppData": true, 
           "setParameters": { 
            "IIS Web Application Name": "[parameters('appName')]" 
           }, 
           "addOnPackages" : [ 
            { 
             "packageUri": "https://mystorageblob.blob.core.windows.net/package/my_first_add_on_package.zip", 
             "AppOffline": true, 
             "setParameters": { 
              "IIS Web Application Name": "[parameters('appName')]", 
             } 
            }, 
            { 
             "packageUri": "https://mystorageblob.blob.core.windows.net/package/my_second_add_on_package.zip", 
             "setParameters": { 
              "IIS Web Application Name": "[parameters('appName')]", 
             } 
            } 
           ] 
          } 
         } 
        ], 
        "properties" : {} 
       } 
      ] 
     }, 
     "mode": "Incremental" 
    } 
}
