Docker kubectl得到豆荚

我在和库伯内特斯战斗。我在谷歌上搜索了很多，并查看了一些答案，例如，但似乎无法让它发挥作用

我已创建docker容器并推送到本地注册表：

sudo docker run -d -p 5000:5000 --name registry registry:2
sudo docker tag i-a/i-a:latest localhost:5000/i-a
sudo docker push localhost:5000/i-a

最后一个命令给出：

The push refers to a repository [localhost:5000/i-a]
e0a33c56cca0: Pushed 
54ab83ede54d: Pushed 
f5a58f369605: Pushed 
cd7100a72410: Pushed 
latest: digest: sha256:0f30cdf6b4a4e0e382a6cae50c1325103c3b987d9e51c42edea2244a82ae1331 size: 1164

执行sudo docker pull localhost:5000/i-a

Using default tag: latest
latest: Pulling from i-a
Digest: sha256:0f30cdf6b4a4e0e382a6cae50c1325103c3b987d9e51c42edea2244a82ae1331
Status: Image is up to date for localhost:5000/i-a:latest

配置文件i-a.yaml：

当我

sudo kubectl得到pods时——所有名称空间
我得到：

...
default       i-a-3400848339-0x6c9   0/1       ImagePullBackOff   0          13m

default       i-a-3400848339-wv092   0/1       ImagePullBackOff   0          13m

ImagePullBackOff
变为
ErrImagePull

当我运行
kubectl description pod I-a-3400848339-0x6c9
时，我得到一个错误

我不知道下一步该去哪里看。。。
（当我浏览到时得到404）
尝试：

spec:
      containers:
      - image: localhost:5000/i-a
        imagePullPolicy: Never
        name: i-a
        ports:
        - containerPort: 8090
      dnsPolicy: ClusterFirst
      restartPolicy: Always

从Spec/containers下的映像中删除“localhost:5000/”，并将ImagePullPolicy设置为Never。它应该允许您从本地注册表中提取此图像。当然，此映像将仅对托管docker私有注册表的节点可用。
