+# DigitalOcean Terraform 自动销毁说明
+
+## 生命周期管理
+
+本配置包含自动销毁功能，可以在指定日期后自动删除所有 DigitalOcean 资源。
+
+## 配置
+
+在 `main.tf` 中设置过期日期：
+
+```hcl
+variable "expiration_date" {
+  description = "Expiration date in YYYY-MM-DD format. Use with destroy script"
+  type        = string
+  default     = "2026-03-03"
+}
+```
+
+## 使用方法
+
+### 1. 手动运行销毁脚本
+
+```bash
+# 使用默认日期（2026-03-03）
+./auto_destroy.sh
+
+# 指定过期日期
+./auto_destroy.sh 2026-03-01
+```
+
+### 2. 设置定时任务（cron）
+
+每天检查一次是否需要销毁资源：
+
+```bash
+# 编辑 crontab
+crontab -e
+
+# 添加以下行（每天凌晨 2 点检查）
+0 2 * * * /home/ben/terraform/digitalocean/auto_destroy.sh 2026-03-03 >> /var/log/do_destroy.log 2>&1
+```
+
+### 3. 手动销毁
+
+如果需要立即销毁所有资源：
+
+```bash
+terraform destroy -auto-approve -var="do_token=$(grep DIGITALOCEAN_TOKEN .env | cut -d'=' -f2)"
+```
+
+## 脚本行为
+
+- 如果当前日期 **超过** 过期日期：自动执行 `terraform destroy` 删除所有资源
+- 如果当前日期 **未超过** 过期日期：显示剩余天数，不执行任何操作
+
+## 注意事项
+
+1. 销毁操作不可逆，请确保在过期日期前备份重要数据
+2. 建议在测试环境中先验证脚本行为
+3. 可以通过修改 `main.tf` 中的 `expiration_date` 变量来延长或缩短资源生命周期
+4. 脚本会自动从 `.env` 文件读取 `DIGITALOCEAN_TOKEN`
+
+## 资源列表
+
+以下资源将在过期后自动删除：
+
+- DigitalOcean Droplet
+- Load Balancer
+- Floating IP
+- SSH Key
+- Project
