Question

我被困在最后一刻，无法找出错误，一切工作正常，但是在群集上部署映像时出现错误：

该图像位于docker hub中，来自aws，我使用docker登录，同时还提供了凭据。

sudo kops validate cluster --state=s3://kops-storage-54321 -o yaml

输出：

Using cluster from kubectl context: tests.k8s.local

nodes:
- hostname: ip-172-20-40-124.us-east-2.compute.internal
  name: ip-172-20-40-124.us-east-2.compute.internal
  role: master
  status: "True"
  zone: us-east-2a
- hostname: ip-172-20-112-165.us-east-2.compute.internal

  name: ip-172-20-60-168.us-east-2.compute.internal

在部署映像时出现错误：

命令：

ubuntu@ip-172-31-30-176:~$  sudo kubectl create deployment magicalnginx --image=amitranjan007/magicalnginx

错误：

error: no matches for extensions/, Kind=Deployment

您可以使用以下方法检查哪些api支持当前的Kubernetes对象：

$ kubectl api-resources | grep deployment
deployments                       deploy       apps                           true         Deployment

这意味着从kubernetes版本1.16开始，只有带有应用程序的apiVersion才是正确的（扩展名不支持Deployment）。

将apiVersion更改为部署Yaml中的apps / v1。

无法在kubernetes（AWS）中部署映像
