# 华为云 RDS 主备倒换演练
## 概述
本工具用于在华为云上安全地执行 RDS 主备倒换（Failover）演练。通过三阶段流水线完成：
```
prepare（准备检查） → execute（执行倒换） → report（生成报告）
```
- **prepare**：查询 RDS HA 实例、检查 IAM 权限、生成实验配置目录，并执行**风险评估**（详见下文专节）
- **execute**：读取配置、执行主备倒换、轮询等待完成、收集日志和监控数据
- **report**：读取配置和执行结果、生成综合 HTML 报告
支持所有 RDS 引擎：MySQL、PostgreSQL、SQL Server、MariaDB、TaurusDB（GaussDB for MySQL）。
## 触发词/触发条件
当用户需要执行 RDS 主备倒换、主备切换、故障演练、failover 实验时触发本 skill。
**触发词**：RDS主备倒换、主备倒换演练、failover、RDS故障演练、主备切换、倒换实验、rds failover、RDS failover、高可用演练、高可用验证、RDS HA切换、主备互换、RDS switchover、数据库故障演练、RDS容灾演练
**触发条件**：
- 用户提到 RDS 主备倒换或 failover 操作
- 用户需要对 HA 类型 RDS 实例执行主备切换
- 用户需要 RDS 故障演练或高可用验证
- 用户需要对 RDS 实例做主备互换或 switchover
- 用户需要验证 RDS 高可用容灾能力
## 前置条件
| 条件 | 说明 | 验证方式 |
|------|------|---------|
| **hcloud CLI** | 已安装并完成认证（KooCLI ≥ 3.0.0） | `hcloud version` |
| **AK/SK** | 通过 hcloud profile 配置（`hcloud configure init`）。脚本仅检查 AK/SK 环境变量**是否存在**（不读取实际值），实际认证由 hcloud profile 完成 | `hcloud RDS ListInstances --cli-region=cn-north-1` |
| **Python 3.8+** | 运行脚本 | `python3 --version` |
| **HA 类型 RDS 实例** | 目标区域内至少存在一个主备实例 | hcloud CLI 查看 |
| **实例状态为 ACTIVE** | 倒换前实例必须处于运行状态 | prepare 阶段自动检查 |
## 配置
共享配置文件 `config/config.json`：
```json

How to install
mdr add huaweicloud/huaweicloud-skills/huawei-cloud-rds-failover@git:20260923.28ce17bmdr add huaweicloud/huaweicloud-skills/huawei-cloud-rds-failover@sha256:4a72da3f6407e60aPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
