无法使用Azure Kubernetes获得服务

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

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
