如何更改现有Service Fabric群集上的操作系统? [英] How to change the OS on an existing Service Fabric cluster?

问题描述

我正在尝试将我的VMSS更改为:

I'm trying to change my VMSS from:

    "imageReference": {
      "publisher": "MicrosoftWindowsServer",
      "offer": "WindowsServer",
      "sku": "2016-Datacenter-with-Containers",
      "version": "latest"
    }

收件人:

    "imageReference": {
      "publisher": "MicrosoftWindowsServer",
      "offer": "WindowsServerSemiAnnual",
      "sku": "Datacenter-Core-1803-with-Containers-smalldisk",
      "version": "latest"
    }

我尝试的第一件事是:

Update-AzureRmVmss -ResourceGroupName "DevServiceFabric" -VMScaleSetName "HTTP" -ImageReferenceSku Datacenter-Core-1803-with-Containers-smalldisk -ImageReferenceOffer WindowsServerSemiAnnual

哪个给我错误:

Update-AzureRmVmss:不允许更改属性"imageReference.offer". 错误代码:PropertyChangeNotAllowed

Update-AzureRmVmss : Changing property 'imageReference.offer' is not allowed. ErrorCode: PropertyChangeNotAllowed

这已在文档中得到确认；您只能在创建比例集后设置报价.

This is confirmed in the docs; you can only set the offer when the scaleset is created.

接下来，我尝试Add-AzureRmServiceFabricNodeType添加新的节点类型，以为以后可以删除旧的节点类型.但是，此命令似乎不允许您设置操作系统映像.您只能设置VM SKU(换句话说，群集中的所有VM必须具有相同的OS).

Next I tried Add-AzureRmServiceFabricNodeType to add a new node type, thinking I could just delete the old one after. However, this command doesn't seem to allow you to set the OS image. You can only set the VM SKU (In other words, all VMs on your cluster have to have the same OS).

是否可以在不删除整个群集且从头开始的情况下更改此设置?

Is there a way to change this without deleting the entire cluster and starting from scratch?

推荐答案

编辑如果您可以停留在当前发布商+报价之内，则可以通过简单地更改SKU来轻松切换操作系统. 请参阅Mike的答案.

Edit If you can stay within the current publisher+offer, you can switch the OS very easily by simply changing the SKU. See the answer by Mike.

如果您确实需要更改报价，可以执行以下操作:

If you really need to change the offer, you can do this:

升级大小主节点类型VM的操作系统和操作系统.

请注意，您需要考虑很多事情，例如可用性级别.集群在一段时间内也将不可用.

大幅缩短:

• 将具有所需操作系统的第二个比例尺集添加到主节点类型
• 禁用旧的比例尺集，然后将其删除
• 切换负载均衡器
