【Azure K8S】演示修复因AKS密钥过期而导致创建服务不成功的问题(The provided client secret keys for app ****** are expired)

问题描述

在Azure Kubernetes 服务中，创建一个Internal Load Balancer服务，使用以下yaml内容：

internallb.yaml

apiVersion: v1
kind: Service
metadata:
  name: ilb-myapp
  annotations:
    service.beta.kubernetes.io/azure-load-balancer-internal: "true"
spec:
  type: LoadBalancer
  ports:
  - port: 80
  selector:
    app: myapp

apply yaml

kubectl apply -f internallb.yaml

查看service状态，一直保持pending

kubectl get service

## 输出结果：
NAME               TYPE           CLUSTER-IP    EXTERNAL-IP   PORT(S)        AGE
ilb-myapp          LoadBalancer   10.0.32.246   <pending>     80:30198/TCP   92m
kubernetes         ClusterIP      10.0.0.1      <none>        443/TCP        13h

查看service日志

"error_description":"AADSTS7000222: The provided client secret keys for app '********-****-****-****-************' are expired

kubectl describe service  ilb-myapp 

##输出结果：

问题解答

根据错误消息，已经得知是 app client secret 已经过期。那么要修复这个问题，就是更换新的 secret。操作步骤有两步：

第一步 ：根据错误消息中的Application ID，在Azure AD中查找到对应的注册应用

在注册应用中，重新生成新的Client Secret，复制保存新的Secret(用于第二步中)

第二步 : 使用 az aks update-credentials 命令，更新AKS集群中的密钥值(Secret Value)

  az aks update-credentials --resource-group <resource group name>  --name <AKS Cluster name>  --reset-service-principal --service-principal <App Application ID>    --client-secret  <第一步中的Secret Value>

命令参考文档：

当命令执行完成后，在此检查 Service 状态，不在是Pending。而是分配了正确的IP地址
