1 导出yaml配置文件

源环境导出部署及服务的yaml文件。以mc服务为例：

kubectl get deployment mc -n kingdee -o yaml > mc-deployment.yaml
kubectl get svc mc -n kingdee -o yaml > mc-svc.yaml

2 修改导出的YAML文件

根据新环境相应信息，修改其中的namespace，集群名称clusterName，WEB_PORT，configUrl，APPSTORE_URL信息。

3 导入容器服务

目标环境导入容器服务。

kubectl create -f mc-deployment.yaml
kubectl create -f mc-svc.yaml
