使用Argocd部署应用

部署helloworld

[root@master 07-argocd-basics]# kubectl apply -f 01-application-helloworld.yaml 
application.argoproj.io/spring-boot-helloworld created
[root@master 07-argocd-basics]# cat 01-application-helloworld.yaml 
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:

已经运行正常

分别在三个名称空间部署helloworld
