Question

我正在尝试通过Visual Studio升级我的Service Fabric应用程序。

我最终不得不使用diff软件包方法来确保只有我更改的服务才在升级中。

我通过命令文件删除了不需要的文件。

现在，我进入了另一个错误，该错误由于缺乏细节而烦人：

Start-ServiceFabricApplicationUpgrade : Default service descriptions can not be modified as part of upgrade. Modified 
2>default service: fabric:/MYAPPLICATION/MYSERVICE. To allow it, set 
2>EnableDefaultServicesUpgrade to true.

我该放在哪里？

请注意，这来自Visual Studio。

使用PowerShell很少能获得喜悦。

我已经看到了对Update-ServiceFabricService CmdLet的引用，但是没有关于我需要做什么的更多信息。

我在应用程序清单中尝试了此尝试，但没有成功：

首先，在给您解决方案之前，我将给出一个原因...

EnableDefaultServicesUpgrade是一个标志，用于允许在应用程序升级期间升级默认服务描述。设置为true时，默认服务描述将被新值覆盖，这是必需的，以防止对描述的意外更改而导致可能的故障或数据丢失。

设置为 false （默认）时，它将进行检查以防止发生故障
设置为 true 时，您将承担这些更改安全的风险

例如，当您更改服务中的分区数时，SF预测这将导致数据丢失或其他故障。

解决方法：

EnableDefaultServicesUpgrade是群集定义中的标志，而不是服务中的标志。您必须在群集清单中进行设置。

您的集群清单将具有一个类似于以下内容的部分：

...some stuff above...
{
  "name": "ClusterManager",
  "parameters": [
  {
    "name": "EnableDefaultServicesUpgrade",
    "value": true
  }]
  ... some more stuf below
 }

要在 Azure 上进行更改：

您可以按照http://resources.azure.com

中的说明使用门户网站“ this link”

在 本地群集上：

您从集群安装文件夹中复制clusterconfig.json，使用以下命令Start-ServiceFabricClusterConfigurationUpgrade -ClusterConfigPath .\clusterconfig.json

应用更改触发集群升级

顺便说一句...

您正在使用DefaultServices，应该避免使用它，为什么会有很多问题。

不能将默认服务描述作为升级集的一部分进行修改，将EnableDefaultServicesUpgrade设置为true
