默认服务描述不能作为升级的一部分进行修改，将 EnableDefaultServicesUpgrade 设置为 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，该错误因缺乏细节而令人恼火：

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.

我应该把它放在哪里？

请注意，这是来自 Visual Studio。

我很少从使用 PowerShell 中获得乐趣。

我看到了对 Update-ServiceFabricService CmdLet 的引用，但没有关于我需要做什么的更多信息。

我已经在应用程序清单中尝试过但没有成功：

首先，在我给你解决方案之前，我会给出一个理由...

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，默认服务描述将被新值覆盖，这是为了防止意外更改描述而导致可能的故障或数据丢失。

当设置为false（默认）时，它会进行检查以防止故障发生，
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时，SF 预测这将导致数据丢失或其他故障。

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：

您可以使用传送门'http://resources.azure.com' as described in this link

在本地集群上：

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

顺便说一句...

你正在使用 DefaultServices，你应该避免它，关于 SO 为什么的问题有很多。

默认服务描述不能作为升级的一部分进行修改，将 EnableDefaultServicesUpgrade 设置为 true

Default service descriptions can not be modified as part of upgrade set EnableDefaultServicesUpgrade to true
