创建ConfigMap的几种形式演示实例：
1.//创建文件夹
[root@k8s-master01 ~]# mkdir configmap
[root@k8s-master01 ~]# cd configmap/
2.//分别创建2个文件conf
2.1创建conf/game.conf
[root@k8s-master01 configmap]# mkdir conf
[root@k8s-master01 configmap]# vim conf/game.conf
lives=3
secret.code=true
2.2创建conf/game2.conf
[root@k8s-master01 configmap]# vim conf/game2.conf
color.good=purple
user=tomcatroot
3.// 进入configmap/conf查看文件
[root@k8s-master01 configmap]# ls
[root@k8s-master01 configmap]# ls conf/
game2.conf game.conf
//假设game2是nginx，game.conf是redis
4.// 查看帮助
[root@k8s-master01 configmap]# kubectl create configmap –h
