azure - 在azure kubernetes集群中部署Windows服务

Question

我想在azure集群中部署Windows服务。我已经创建了用于部署服务的 yaml 文件，但是当我运行 kubectr get pods 时，我得到以下内容，

NAME                                    READY   STATUS             RESTARTS   AGE
windowsservice-deploy-5994764596-jfghj   0/1     ImagePullBackOff   0          39m

我的 yaml 文件如下所示，

apiVersion: apps/v1
kind: Deployment
metadata:
  name: windowsservice-deploy
  labels:
    app: windowsservice
spec:
  replicas: 1
  template:
    metadata:
      name: windowsservice
      labels:
        app: windowsservice
    spec:
      containers:
      - name: windowsservice
        image: windowskube.azurecr.io/windowsimage:v1
        imagePullPolicy: IfNotPresent
      restartPolicy: Always
  selector:
    matchLabels:
      app: windowsservice


---

apiVersion: v1
kind: Service
metadata:
  name: windows-service
spec:
  selector:
    app: windowsservice
  ports:
    - port: 80
  type: LoadBalancer

这是输出 kubectl 描述 pod windowsservice-deploy-5994764596-jfghj

这是一个 Windows 服务，我以前没有部署过，我是否遗漏了什么？

谢谢

鉴于 windowskube.azurecr.io/windowsimage:v1 似乎是您的私有(private) Azure 容器注册表，我认为缺少的部分是为 kubernetes 提供私有(private)注册表的登录凭据。

参见:https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/

正如前面提到的，通过执行kubectl描述pod windowsservice-deploy-5994764596-jfghj并向下滚动到底部查看事件，您将获得更好的错误消息描述了图像拉取失败的原因。
