初始化mongo config server 副本集

kubectl exec -it zlgmongo-config-0 -n zlg-zws -- bash

kubectl exec -it zlgmongo-shard-0-0 -n zlg-zws -- bash
mongo --port 27018
rs.initiate(

添加shard

kubectl exec -it `kubectl get po -l app=zlgmongo -n zlg-zws | grep zlgmongo | awk '{print $1}'` -n zlg-zws -- bash
mongo
sh.addShard("zlgmongo-shard-0-0/zlgmongo-shard-0-0.zlgmongo-shard-0.zlg-zws.svc.cluster.local:27018")
