Kubernetes 调度失败：0/3个节点可用：3个POD不足

我正在尝试将我的NodeJS应用程序部署到EKS，并使用完全相同的容器运行3个pod

以下是错误消息：

$ kubectl get pods
NAME                                 READY   STATUS             RESTARTS   AGE
cm-deployment-7c86bb474c-5txqq       0/1     Pending            0          18s
cm-deployment-7c86bb474c-cd7qs       0/1     ImagePullBackOff   0          18s
cm-deployment-7c86bb474c-qxglx       0/1     ImagePullBackOff   0          18s
public-api-server-79b7f46bf9-wgpk6   0/1     ImagePullBackOff   0          2m30s

$ kubectl describe pod cm-deployment-7c86bb474c-5txqq
Events:
  Type     Reason            Age                  From               Message

  Warning  FailedScheduling  23s (x4 over 2m55s)  default-scheduler  0/3 nodes are available: 3 Insufficient pods.

所以它说，

0/3节点可用

但是，如果我运行

kubectl获取节点——观察

$ kubectl get nodes --watch
NAME                                                 STATUS   ROLES    AGE    VERSION
ip-192-168-163-73.ap-northeast-2.compute.internal    Ready    <none>   6d7h   v1.14.6-eks-5047ed
ip-192-168-172-235.ap-northeast-2.compute.internal   Ready    <none>   6d7h   v1.14.6-eks-5047ed
ip-192-168-184-236.ap-northeast-2.compute.internal   Ready    <none>   6d7h   v1.14.6-eks-5047ed


我应用了两个.yaml文件

我怎样才能解决这个问题？
谢谢
我猜，如果不运行清单，您得到的是图像上的图像标签
1
不存在，因此您得到的是
ImagePullBackOff
，这通常意味着容器运行时找不到要提取的图像

看看Docker Hub，那里没有
1
标签，只有
最新的

因此，移除标签或将
1
替换为
latest
都可以解决您的问题
