使用 Helm

背景信息

使用 Helm 在 Kubernetes 集群中引导 ShardingSphere-Proxy 实例进行安装。关于 ShardingSphere Helm Charts 的更多内容可以参考：ShardingSphere-on-Cloud 子项目。

前提条件

  • kubernetes 1.18+
  • kubectl
  • helm 3.3.0+
  • 可以动态申请 PV(Persistent Volumes) 的 StorageClass 用于持久化数据。（可选）

操作步骤

在线安装

  1. 将 ShardingSphere-Proxy 添加到 Helm 本地仓库：
  1. helm repo add shardingsphere https://shardingsphere.apache.org/charts
  1. 以 ShardingSphere-Proxy 命名安装 charts：
  1. helm install shardingsphere-proxy shardingsphere/shardingsphere-proxy

源码安装

  1. 执行下述命令以执行默认配置进行安装。
  1.  git clone https://github.com/apache/shardingsphere-on-cloud.git
  2.  cd charts/shardingsphere-proxy/charts/governance
  3.  helm dependency build 
  4.  cd ../..
  5.  helm dependency build 
  6.  cd ..
  7.  helm install shardingsphere-proxy shardingsphere-proxy

说明：

  1. 其他的配置详见下方的配置列表。
  2. 执行 helm list 获取所有安装的 release。

卸载

  1. 默认删除所有发布记录，增加 --keep-history 参数保留发布记录。
  1. helm uninstall shardingsphere-proxy
