无法更改代理 VM 计数

Question

我创建了一个代理计数为 1 的 ACS Kubernetes 集群。我前往门户将代理计数增加到 2，并收到一般错误，提示为容器服务配置资源失败。

查看活动日志，还有更多信息。

写入 ContainerServices - PreconditionFailed - 为容器服务“xxxxxxx”提供资源 资源组“xxxxxxxx”失败。

---

验证 - 无效模板 - 部署模板验证失败：模板中未定义资源“Microsoft.Network/networkSecurityGroups/k8s-master-3E4D5818-nsg”。请参阅https://aka.ms/arm-template了解使用详情。'。

尝试通过 Azure CLI 2.0 更改它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 模板建立了集群。

Answer 1

这是旧集群的已知服务问题。目前正在推出一个修复程序，并在此 github 问题中进行跟踪，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 编辑代理池计数：
