项目地址：https://github.com/goodrain/rainbond
helm安装rainbond
Helm chart地址：https://github.com/goodrain/rainbond-chart
前置要求：
准备3个kubernetes节点
root@node1:~# kubectl get nodes -o wide
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
node1 Ready control-plane 33d v1.27.3 192.168.72.30 <none> Ubuntu 22.04.2 LTS 5.15.0-76-generic containerd://1.6.21
node2 Ready control-plane 33d v1.27.3 192.168.72.31 <none> Ubuntu 22.04.2 LTS 5.15.0-76-generic containerd://1.6.21
node3 Ready control-plane 33d v1.27.3 192.168.72.32 <none> Ubuntu 22.04.2 LTS 5.15.0-76-generic containerd://1.6.21
准备可用的storageclass，支持RWO及RWX，本示例为openebs-hostpath 以及openebs-nfs
root@node1:~# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
openebs-hostpath (default) openebs.io/local Delete WaitForFirstConsumer false 33d
openebs-kernel-nfs openebs.io/nfsrwx Delete Immediate false 17h
添加Rainbond Helm 仓库
helm repo add rainbond https://openchart.goodrain.com/goodrain/rainbond
安装rainbond
helm install rainbond rainbond/rainbond-cluster \
-n rbd-system --create-namespace \
--set operator.env[0].name=CONTAINER_RUNTIME \
--set operator.env[0].value=containerd \
--set Cluster.RWX.enable=true \
--set Cluster.RWX.config.storageClassName=openebs-kernel-nfs \
--set Cluster.RWO.enable=true \
--set Cluster.RWO.storageClassName=openebs-hostpath
参数说明：
- CONTAINER_RUNTIME ，指定容器运行时为containerd，与kubernetes集群一致
- storageClassName，指定rainbond使用的存储类
等待rainbond部署完成，查看运行的pods
