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，能够支持RWO及RWX，本示例为longhorn，能够同时支持RWO及RWX两种类型。longhorn数据存储路径/var/lib/longhorn/所在磁盘大小推荐200G.

# kubectl get sc
NAME                 PROVISIONER                    RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
longhorn (default)   driver.longhorn.io             Delete          Immediate              true                   48m

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=longhorn \
--set Cluster.RWO.enable=true \
--set Cluster.RWO.storageClassName=longhorn

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
