Question

我有一个ACS Kubernetes集群，它是在代理计数为1的情况下创建的。我去了门户网站，将代理计数增加到2，并收到一个通用错误，指出为容器服务配置资源失败。 / p>

查看活动日志，可以获得更多信息。

Write ContainerServices - PreconditionFailed - 为容器服务'xxxxxxx'提供资源资源组'xxxxxxxx'失败。

验证 - InvalidTemplate - 部署模板验证失败：'资源'Microsoft.Network/networkSecurityGroups/k8s-master-3E4D5818-nsg'未在模板中定义。有关使用详情，请参阅https://aka.ms/arm-template。'。

尝试通过Azure CLI 2.0进行更改也会返回相同的错误。

更新：根据quickstart templates repo中的示例，使用具有单个容器服务资源的ARM模板启动群集。

Answer 1

这是旧群集的已知服务问题。目前正在推出修复程序，并在此github问题https://github.com/Azure/ACS/issues/16

Answer 2

我在我的实验室中使用此模板进行了测试，但我无法重现您的错误。请尝试使用azure resource explorer编辑代理池的计数：

无法更改代理VM计数
