Kubernetes 从私有注册表拉取镜像失败 --> 未知字段“imagePullPolicy”

Question

我正在尝试从我的 priavte 港口注册表中提取图像。在 Kubernetes 中，我首先创建了一个秘密，如本文档中所述：

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

然后我尝试将其实现到我的deployment.yaml中：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx-k8s-test9
  namespace: k8s-test9
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx-k8s-test9
    spec:
      containers:
      - name: nginx-k8s-test9
        image: my-registry.com/nginx-test/nginx:1.14.2
      imagePullSecrets:
      - name: harborcred
        imagePullPolicy: Always
        volumeMounts:
          - name: webcontent
            mountPath: usr/share/nginx/html
        ports:
        - containerPort: 80
      volumes:
        - name: webcontent
          configMap:
            name: webcontent
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: webcontent
  namespace: k8s-test9
  annotations:
    volume.alpha.kubernetes.io/storage-class: default
spec:
  accessModes: [ReadWriteOnce]
  resources:
    requests:
      storage: 5Gi

当我尝试创建部署时，收到以下错误消息：

error: error validating "deployment.yaml": error validating data: [ValidationError(Deployment.spec.template.spec.imagePullSecrets[0]): unknown field "imagePullPolicy" in io.k8s.api.core.v1.LocalObjectReference, ValidationError(Deployment.spec.template.spec.imagePullSecrets[0]): unknown field "ports" in io.k8s.api.core.v1.LocalObjectReference, ValidationError(Deployment.spec.template.spec.imagePullSecrets[0]): unknown field "volumeMounts" in io.k8s.api.core.v1.LocalObjectReference]; if you choose to ignore these errors, turn validation off with --validate=false

我猜这是一个 yaml 问题，但我不知道它应该在哪里。

这是解决方案：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx-k8s-test9
  namespace: k8s-test9
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx-k8s-test9
    spec:
      containers:
      - name: nginx-k8s-test9
        image: my-registry.com/nginx-test/nginx:1.14.2
        volumeMounts:
          - name: webcontent
            mountPath: usr/share/nginx/html
        ports:
        - containerPort: 80
      volumes:
        - name: webcontent
          configMap:
            name: webcontent
      imagePullSecrets:
      - name: harborcred-test
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: webcontent
  namespace: k8s-test9
  annotations:
    volume.alpha.kubernetes.io/storage-class: default
spec:
  accessModes: [ReadWriteOnce]
  resources:
    requests:
      storage: 5Gi

imagePullSecrets 部分不在正确的位置。
