无法更改代理 VM 计数

Question

我有一个创建时代理数为 1 的 ACS Kubernetes 集群。我去门户网站将代理数增加到 2 并收到一般错误，指出容器服务的资源配置失败.

查看 activity 日志，有更多信息。

Write ContainerServices - PreconditionFailed - Provisioning of resource(s) for container service 'xxxxxxx' in resource group 'xxxxxxxx' failed.

Validate - InvalidTemplate - Deployment template validation failed: 'The resource 'Microsoft.Network/networkSecurityGroups/k8s-master-3E4D5818-nsg' is not defined in the template. Please see https://aka.ms/arm-template for usage details.'.

尝试通过 Azure CLI 2.0 更改它也 returns 同样的错误。

更新：基于 quickstart templates repo.

中的示例，集群是使用带有单个容器服务资源的 ARM 模板建立起来的

Answer 1

我在实验室中使用此模板进行了测试，但无法重现您的错误。请尝试使用 azure resource explorer 来编辑代理池的数量：

Answer 2

这是旧集群的已知服务问题。目前正在推出修复程序，并正在跟踪此 github 问题，https://github.com/Azure/ACS/issues/16
