The cubefs-helm repository can help you deploy CubeFS cluster quickly in containers orchestrated by kubernetes. Kubernetes 1.12 and Helm 3 are required. cubefs-helm has already integrated CubeFS CSI plugin
$ git clone https://github.com/cubefs/cubefs-helm
$ cd cubefs-helm
CubeFS CSI driver will use client-go to connect the Kubernetes API Server. First you need to copy the kubeconfig file to cubefs-helm/cubefs/config/
directory, and rename to kubeconfig
$ cp ~/.kube/config cubefs/config/kubeconfig
Create a cubefs.yaml
file, and put it in a user-defined path. Suppose this is where we put it.
$ cat ~/cubefs.yaml
path:
data: /cubefs/data
log: /cubefs/log
datanode:
disks:
- /data0:21474836480
- /data1:21474836480
metanode:
total_mem: "26843545600"
provisioner:
kubelet_path: /var/lib/kubelet
Note that
cubefs-helm/cubefs/values.yaml
shows all the config parameters of CubeFS. The parameterspath.data
andpath.log
are used to store server data and logs, respectively.
You should tag each Kubernetes node with the appropriate labels accorindly for server node and CSI node of CubeFS.
kubectl label node <nodename> cubefs-master=enabled
kubectl label node <nodename> cubefs-metanode=enabled
kubectl label node <nodename> cubefs-datanode=enabled
kubectl label node <nodename> cubefs-csi-node=enabled
$ helm install cubefs ./cubefs -f ~/cubefs.yaml
