0x00 Problem

[root@k8sm90 demo]# kubectl create -f tomcat-deployment.yaml
error: unable to recognize "tomcat-deployment.yaml": no matches for kind "Deployment" in version "extensions/v1beta1"

0x01 Solution

修改 apiVersion 选项： apps/v1

[root@k8sm90 demo]# cat tomcat-deployment.yaml
apiVersion: apps/v1
kind: Deployment
...

因为我的 k8s 版本是 1.16.2，在这个版本中 Deployment 已经从 extensions/v1beta1 弃用

DaemonSet, Deployment, StatefulSet, and ReplicaSet resources will no longer be served from extensions/v1beta1, apps/v1beta1, or apps/v1beta2 by default in v1.16.
