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

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
答案 0 :(得分:1)
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。
