Question

我正在尝试配置azure kubernetes集群，并在portal.dockerized .net核心webapi项目上创建了一个集群，还将映像发布到了Azure容器注册器。应用清单文件后，我得到创建服务的消息以及外部IP。但是，当我得到豆荚时，我一直都处于“待处理”状态

  NAME                           READY     STATUS    RESTARTS   AGE
  kubdemo1api-6c67bf759f-6slh2   0/1       Pending   0          6h

这是我的Yaml清单文件，有人可以在这里提出问题吗？

编辑：输出kubectl描述吊舱是这个

在这里

Answer 1

对于您提供的错误，它表明您必须进行身份验证才能从Azure容器注册表中提取图像。

实际上，您只需要拉取图像的权限，并且acrpull角色就足够了。有两种方法可以实现它。

一个是仅授予AKS访问Azure容器注册表的权限。在我这边最简单。只需为AKS使用的服务主体创建角色分配。有关整个步骤，请参见Grant AKS access to ACR。

另一个是使用Kubernetes秘密的。它比第一个复杂一些。您需要创建一个与使用的AKS不同的新服务主体并授予对其的访问权限，然后使用该服务主体创建kubernetes机密。有关整个步骤，请参见Access with Kubernetes secret。

此Yaml是错误的您能提供正确的Yaml，意图是错误的。尝试以下YAML

apiVersion: extensions/v1beta1

      maxUnavailable: 1
    type: RollingUpdate
  minReadySeconds: 30
  selector:
    matchLabels:
      app: kubdemo1api
  template:
    metadata:
      labels:

无法使用Azure Kubernetes获得服务
