导入镜像

上传编译arm版本的镜像deploy.deepexi.com/daas/arm/deepexi-daas-eureka-server:2.7.x.20210817_arm，安装到服务器，然后导入镜像

deepexi-daas-eureka- server:2.7.x.20210817_arm

图1 导入镜像

创建Eureka集群

1. 通过k8s创建，上传eureka-pro.yaml文件到k8s master，然后执行：

   # kubectl create -f eureka-pro.yaml

   图2 执行1
   

   # kubectl -n applife get pods,ep,svc | grep eureka

   图3 执行2
   
2. 看到上面提示/结果，表示创建成功。
