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才会升级。
我通过命令文件执行此操作，删除了不需要的文件。
现在我遇到了另一个错误，该错误因其缺乏细节而令人烦恼:
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 中获得任何乐趣。
我已经看到对 Update-ServiceFabricService CmdLet 的引用，但没有更多关于我需要做什么的信息。
我在应用程序 list 中尝试过此操作，但没有成功:

最佳答案
首先，在给你解决方案之前，我先给出一个理由......
EnableDefaultServicesUpgrade 是一个标志，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
一个例子是，当您更改服务中的分区数量时，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 list 中进行设置。
您的集群 list 将有一个如下所示的部分:
...some stuff above...
{
"name": "ClusterManager",
"parameters": [
{
"name": "EnableDefaultServicesUpgrade",
"value": true
}]
... some more stuf below
}
要在Azure上更改它:
您可以使用门户'http://resources.azure.com ' 如 this link 中所述
在本地集群上:
从集群安装文件夹复制 clusterconfig.json，使用以下命令应用更改并触发集群升级 Start-ServiceFabricClusterConfigurationUpgrade -ClusterConfigPath .\clusterconfig.json
顺便说一下...
您正在使用 DefaultServices，您应该避免它，有很多关于为什么的问题。
关于c# - 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，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51798976/
