helm部署mongodb集群
    配置：
    node1-iot.com，ip：192.168.0.201
    node2-iot.com ip：192.168.0.202
    node3-iot.com ip：192.168.0.204
    
    一：部署helm以及storageclass查看其它文章
    
    二：helm部署mongodb集群
    [root@master-iot mongodb]# helm repo add stable https://kubernetes-charts.storage.googleapis.com/
    [root@master-iot mongodb]# helm fetch  stable/mongodb-replicaset
    [root@master-iot mongodb]# tar zxvf mongodb-replicaset-3.11.2.tgz
    [root@master-iot mongodb]# cd mongodb-replicaset/
    [root@master-iot mongodb-replicaset]# vim values.yaml

![在这里插入图片描述][20200105144133710.png]

改为自己的storageclass [root@master-iot mongodb]# helm install -f mongodb-replicaset/values.yaml --name mongodb-ha stable/mongodb-replicaset --namespace mongod [root@master-iot ~]# kubectl get all -n mongod NAME READY STATUS RESTARTS AGE pod/mongodb-ha-mongodb-replicaset-0 1/1 Running 0 63m pod/mongodb-ha-mongodb-replicaset-1 1/1 Running 0 62m pod/mongodb-ha-mongodb-replicaset-2 1/1 Running 0 60m NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/mongodb-ha-mongodb-replicaset ClusterIP None <none> 27017/TCP 63m service/mongodb-ha-mongodb-replicaset-client ClusterIP None <none> 27017/TCP 63m NAME READY AGE statefulset.apps/mongodb-ha-mongodb-replicaset 3/3 63m 三：测试 [root@master-iot ~]# kubectl exec -it mongodb-ha-mongodb-replicaset-0 -n mongod bash mongodb@mongodb-ha-mongodb-replicaset-0:/$ mongo --host localhost --port 27017 MongoDB shell version v3.6.16 connecting to: mongodb://localhost:27017/?gssapiServiceName=mongodb Implicit session: session {  "id" : UUID("a2c98d61-085e-4a97-a487-9463b6d551d3") }
