【问题描述】：
我正在学习 K8s，并使用 kubectl apply 设置了发布管道。我已经通过 Terraform 设置了 AKS 集群，在第一次运行时一切似乎都很好。一旦我破坏了集群，我重新运行了管道，我得到了我认为与异常中提到的 kubeconfig 文件有关的问题。我尝试了 cloud shell 等来获取文件或重置它，但我没有成功。我怎样才能回到干净的状态？

发布管道的更新、工作流任务：
最初我得到了工件，克隆了包含 k8s yamls 的 repo，然后这个阶段应用了 kubectl。

【问题讨论】：
-
您能否分享管道步骤并提供更多详细信息。您是否在管道本身中为新创建的集群获取 kubeconfig？
-
我已经更新了 OP，我没有获取 kubeconfig。
-
Kubectl 将需要信息来连接到您的新集群。您将需要获取集群信息并使用集群的详细信息更新您的 kubeconfig 文件。其中一种方法是，您可以在管道中调用 kubectl apply 之前使用 Az CLI 任务 (az aks get-credentials) 更新 kubeconfig。
-
我在 kubectl apply 任务之前使用了 Radek 在任务中给出的命令，但同样的问题。一定还是做错了什么。

您是否仍然收到“无法连接到服务器：拨号 tcp：查找 mq-k8s-dfee38f6.hcp.switzerlandnorth.azmk8s.io”？如果是新的错误信息，可以在这里添加吗？
