我在一台机器上使用kubernetes进行测试,我已经从Nginx docker图像构建了一个自定义图像,但是当我尝试在kubernetes中使用图像时,我得到一个图像拉错误?????

我的POD YAML

kind: Pod
apiVersion: v1
Metadata:
  name: yumserver
  labels:
    name: frontendhttp
spec:
  containers:
    - name: myfrontend
      image: my/Nginx:latest
      ports:
        - containerPort: 80
          name: "http-server"
      volumeMounts:
      - mountPath: "/usr/share/Nginx/html"
        name: mypd
  imagePullSecrets:
    - name: myregistrykey

  volumes:
    - name: mypd
      persistentVolumeClaim:
       claimName: myclaim-1

我的KUBERNETES命令

kubectl create -f pod-yumserver.yaml

错误

kubectl describe pod yumserver
