## Helm chart to Run a ChubaoFS Cluster in Kubernetes
The [chubaofs-helm](https://github.com/chubaofs/chubaofs-helm) repository can help you deploy ChubaoFS cluster quickly in containers orchestrated by kubernetes.
Kubernetes 1.16+ and Helm 3 are required.
Kubernetes 1.12+ and Helm 3 are required. chubaofs-helm has already integrated ChubaoFS CSI plugin
Initialize Helm:
### Download chubaofs-helm
```
$ helm init
```
$ git clone https://github.com/chubaofs/chubaofs-helm
$ cd chubaofs-helm
```
Add repository to download Helm chart of ChubaoFS:
### Copy kubeconfig file
ChubaoFS CSI driver will use client-go to connect the Kubernetes API Server. First you need to copy the kubeconfig file to `chubaofs-helm/chubaofs/config/` directory, and rename to kubeconfig
```
$ helm repo add chubaofs https://chubaofs.github.io/chubaofs-charts
$ helm repo update
```
$ cp ~/.kube/config chubaofs/config/kubeconfig
```
Create the configuration file `chubaofs.yaml` and put it in a user-defined path.
### Create configuration yaml file
Create a `chubaofs.yaml` file, and put it in a user-defined path. Suppose this is where we put it.
```
$ cat ~/chubaofs.yaml

Label the nodes in Kubernetes according to different roles(master/metanode/datanode):
### Add labels to Kubernetes node
You should tag each Kubernetes node with the appropriate labels accorindly for server node and CSI node of ChubaoFS.
```
$ kubectl label node <nodename> chuabaofs-master=enabled
$ kubectl label node <nodename> chuabaofs-metanode=enabled
$ kubectl label node <nodename> chuabaofs-datanode=enabled
kubectl label node <nodename> chuabaofs-master=enabled
kubectl label node <nodename> chuabaofs-metanode=enabled
kubectl label node <nodename> chuabaofs-datanode=enabled
kubectl label node <nodename> chubaofs-csi-node=enabled
```
Install ChubaoFS cluster with Helm:
### Deploy ChubaoFS cluster
```
$ helm install chubaofs chubaofs/chubaofs --version 1.5.0 -f ~/chubaofs.yaml
$ helm install chubaofs ./chubaofs -f ~/chubaofs.yaml
```
Delete ChubaoFS cluster:
```
$ helm delete chubaofs
```
Refer to [chubaofs-helm](https://github.com/chubaofs/chubaofs-helm/blob/master/README.md) for deployment with Helm 2 and deployment of monitoring system.
