3.启动yapi，mongodb服务

cd /home/yapi
kubectl apply -f .
kubectl get pod,svc 

4.访问用户密码：admin@qq.com /admin123
http://k8s-master-ip:30000/

5.数据迁移：

mongo数据备份：
# mongodump  -h 192.168.1.151  --port 30075  -u root -p admin@123456 -d yapi -o /home/yapi
mongo 数据恢复：
# mongorestore -h localhost -u root -p admin@123456 -d yapi  /home/yapi/yapi
