无法使用蔚蓝kubernetes的服务

Question

我正在尝试配置azure kubernetes集群并在portal.dockerized .net核心webapi项目上创建一个集群，并将图像发布到azure容器寄存器。应用清单文件后，我会收到已创建服务的消息以及外部IP。然而，当我获得pods时，我总是获得“待定”状态

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

这是我的yaml清单文件，有人可以提出这里有什么问题吗？

编辑：输出kubectl描述pods就是这个

就这个

Answer 1

对于您提供的错误，它显示您必须进行身份验证才能从Azure容器注册表中提取映像。

实际上，你只需要获得许可来拉动图像，而acrpull角色就足够了。有两种方法可以实现它。

一种是只授予对Azure容器注册表的AKS访问权限。这对我来说最简单。只需要为AKS使用的服务主体创建角色分配。有关整个步骤，请参阅Grant AKS access to ACR。

另一个是使用Kubernetes的秘密。它比第一个复杂一点。您需要创建一个与使用的AKS不同的新服务主体并授予对它的访问权限，然后使用服务主体创建kubernetes机密。有关整个步骤，请参阅Access with Kubernetes secret。

这个Yaml是错的你能提供正确的yaml，意图是错的。尝试下面的YAML

apiVersion: extensions/v1beta1

  labels:
    name: kubdemo1api

  replicas: 1
  strategy:

      maxSurge: 1
      maxUnavailable: 1
    type: RollingUpdate
  minReadySeconds: 30
  selector:
    matchLabels:
      app: kubdemo1api
  template:
    metadata:
      labels:
        app: kubdemo1api
        version: "1.0"
        tier: backend
