我正在创建一个脚本,我可以使用该脚本将Azure Service Fabric应用程序部署到本地群集或Azure托管群集。如果我运行脚本两次,我遇到了问题。第二次执行脚本时Connect-ServiceFabricCluster
命令失败。我可以重新启动PowerShell控制台或PowerShell ISE,直到第二次调用才会再次出现此问题。这导致了更改脚本的繁琐过程。

{
Param (
[System.Xml.XmlElement]
$Element

$hashtable = @{}

return $hashtable

如果您查看了Visual Studio在创建Azure Service Fabric应用程序时创建的Deploy-FabricApplication.ps1
脚本,则此代码应该看起来很熟悉,因为这是我在脚本中使用的源代码。
我第二次运行脚本时看到的错误消息是:
WARNING: Failed to contact Naming Service. Attempting to contact Failover Manager Service...
WARNING: Failed to contact Failover Manager Service, Attempting to contact FMM...
WARNING: Service Fabric cluster may not be connected.
Connect-ServiceFabricCluster : One or more errors occurred.

My Local.xml Publish Profile,我没有对它进行任何更改,它是Visual Studio在创建项目时创建的默认文件。
<?xml version="1.0" encoding="utf-8"?>
<PublishProfile xmlns="http://schemas.microsoft.com/2015/05/fabrictools">
<ClusterConnectionParameters />
<ApplicationParameterFile Path="..\ApplicationParameters\Local.xml" />
</PublishProfile>
我在看到问题时采取的步骤:
多次连接到Azure中的群集时,只有连接到本地群集时才会看到此问题。
在第二次运行中没有遇到问题,我有什么遗漏吗?我想知道我是否缺少断开连接命令,因为重启会清除任何保留的状态,但是我没有发现任何与服务结构集群命令断开的情况。
我确实在SO上发现了this post,这似乎是同样的错误,但重现问题的路径是不同的。
答案 0 :(得分:1)
要解决此问题,我在Local.xml Publish Profile
中指定了ConnectionEndpoint<?xml version="1.0" encoding="utf-8"?>
<PublishProfile xmlns="http://schemas.microsoft.com/2015/05/fabrictools">
<ClusterConnectionParameters ConnectionEndpoint="localhost:19000" />
<ApplicationParameterFile Path="..\ApplicationParameters\Local.xml" />
</PublishProfile>
