为什么 kubernetes 无法从本地注册表中提取？

我想在树莓派 kubernetes 集群上部署我的容器。

我的 yml 如下所示

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-nginx
spec:
  selector:
    matchLabels:
      run: my-nginx
  replicas: 1
  template:
    metadata:
      labels:
        run: my-nginx
    spec:
      containers:
      - name: my-nginx
        image:   192.168.178.37:5000/my-nginx
        imagePullPolicy: Always
        ports:
        - containerPort: 80

---
apiVersion: v1
kind: Service
metadata:
  name: my-nginx-service
  labels:
    run: my-nginx
spec:
  type: NodePort 
  ports:
    - port: 80
      targetPort: 80
      nodePort: 30007
  selector:
    run: my-nginx

但我收到以下错误

pi@master-pi4 ~/Project/htmlBasic % kubectl restart

我补充道insecure registries

 % cat /etc/docker/daemon.json
{ "insecure-registries":["192.168.178.37:5000"] }

我能够从本地注册表中提取数据。

% docker pull 192.168.178.37:5000/my-nginx
Using default tag: latest
latest: Pulling from my-nginx
Digest: sha256:d498979a2da64b098e25938a0ff0dd611959d791f726d6590f671d471aefed05
Status: Image is up to date for 192.168.178.37:5000/my-nginx:latest
192.168.178.37:5000/my-nginx:latest

如何配置 Kubernetes 以便能够从我的本地注册表中提取数据？我使用的是 Kubernetes 的设置这里

你需要确保集群中的所有节点都有相同的/etc/docker/daemon.json文件
