默认服务描述不能作为升级设置的一部分进行修改，EnableDefaultServicesUpgrade 为 true

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 包方法来确保只有我更改的服务在升级中。

我是通过删除不需要的文件的命令文件完成的。

现在我遇到了另一个错误，由于缺乏细节而令人讨厌：

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.

我到底把这个放在哪里？

请注意，这是来自 Visual Studio。

我很少在使用 PowerShell 时获得任何乐趣。

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过这个，但没有成功：

首先，在给你解决方案之前，先给个理由……

EnableDefaultServicesUpgrade是允许在应用程序升级期间升级默认服务描述的标志。当设置为 true 时，默认服务描述会被新值覆盖，这是为了防止对描述的意外更改而导致可能的故障或数据丢失。

• 当设置为false（默认）时，它将进行检查以防止发生故障，
• 当设置为true 时，您承担这些更改是安全的风险

例如，当您更改服务中的分区数量并且 SF 预测这将导致数据丢失或其他故障时。

修复：

EnableDefaultServicesUpgrade是集群定义中的标志，而不是服务中的标志。您必须在集群清单中进行设置。

您的集群清单将包含如下所示的部分：

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

要在Azure上更改它：

您可以使用此链接中所述的门户“ http://resources.azure.com ”

在本地集群上：

您clusterconfig.json从集群安装文件夹复制，使用以下命令应用更改触发集群升级Start-ServiceFabricClusterConfigurationUpgrade -ClusterConfigPath .\clusterconfig.json

顺便一提...

您正在使用 DefaultServices，您应该避免使用它，关于 SO 为什么有很多问题。
