我有一个由Dockerfile创建的以下图像：

REPOSITORY   TAG      IMAGE ID       CREATED       SIZE 
ruby/lab     latest   f1903b1508cb   2 hours ago   729.6 MB

我有以下YAML文件：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: ruby-deployment
spec:
  replicas: 2
  template:
    metadata:
      labels:
        app: ruby
    spec:
      containers:
      - name: ruby-app
        image: ruby/lab
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 4567

创建部署时，我在窗格中获得以下信息：

ruby-deployment-3830038651-sa4ii   0/1       ImagePullBackOff   0          7m
ruby-deployment-3830038651-u1tvc   0/1       ImagePullBackOff   0          7m

和Failed to pull image "ruby/lab:latest": Error: image ruby/lab not found下面的错误：

 8m            2m              6       {kubelet minikube}      spec.containers{ruby}   Normal          Pulling         pulling image "ruby/lab:latest"
 8m            2m              6       {kubelet minikube}      spec.containers{ruby}   Warning         Failed          Failed to pull image "ruby/lab:latest": Error: image ruby/lab not found
 8m            2m              6       {kubelet minikube}                              Warning         FailedSync      Error syncing pod, skipping: failed to "StartContainer" for "ruby" with ErrImagePull: "Error: image ruby/lab not found"

为此，在docker中真正有必要注册吗？我只想在本地进行测试并将我的代码/存储库传递给朋友以进行测试

谢谢
