本文档描述 Rainbond Helm Chart 的安装配置选项

安装Rainbond

您可以配置values.yaml文件来个性化安装Rainbond

1: 首先您要添加和更新仓库

helm repo add rainbond https://openchart.goodrain.com/goodrain/rainbond
helm repo update
kubectl create namespace rbd-system

2: 编辑配置文件

编写下方values.yaml文件

Cluster:
  # 针对于Rainbond平台的高可用，而不是针对自己业务的高可用
  # Enable the HA installation
  enableHA: false
  # Enable cluster environment detectio
  enableEnvCheck: true
  # Use an external image repository
  # 定义是否使用外部镜像镜像仓库，true为开，false为关，需要用户提供已存在的镜像仓库的 域名、空间名称、用户名以及密码。
  # 开启的好处：不占用本地储存空间，解耦合
  # 开启的弊端：push或者pull镜像时候，可能公网访问镜像仓库，受限于网络传输速度。

helm install rainbond rainbond/rainbond-cluster -f values.yaml -n rbd-system

Operator 配置

Values.yaml 示例配置

operator:
  name: rainbond-operator

    name: registry.cn-hangzhou.aliyuncs.com/goodrain/rainbond-operator
    tag: v5.16.0-release
    pullPolicy: IfNotPresent

  env:
  - name: CONTAINER_RUNTIME
    value: docker

Cluster 配置

高可用安装

高可用模式下必须提供外部数据库、外部 Etcd 、外部共享存储(RWX)

配置外部镜像仓库

配置外部ETCD

配置外部存储

如果使用阿里云 NAS 存储，需要配置 Cluster.RWX.type=aliyun Cluster.RWX.config.server=<SERVER>:/，Rainbond 会自动安装阿里云 NAS CSI 并对接使用。

配置 Rainbond 集群端数据库

配置 Rainbond 控制台数据库

配置集群对外 IP

设置 SLB 或 VIP 来保障 Rainbond 网关的高可用

配置网关节点

配置构建节点

配置集群端镜像获取地址

配置安装版本

配置集群端镜像拉取策略

配置集群副本

配置集群环境检测

配置 rbd-api 参数

配置 rbd-gateway 参数

使用 K3s Containerd
