2026 15:30:00 +0800</pubDate><author>17691281867@163.com (Wenzhuo Huang)</author><guid>https://socake.github.io/playbook/aurora-public-access-tightening/</guid><description>很多团队的生产 Aurora 长期挂着 0.0.0.0/0 全协议规则，加上几条来源不明的 IP 白名单。直接删规则会立刻打断跨 Region 服务和开发者本地调试，于是收紧工作年复一年被推迟。本文给出一条工程化路径：先用 Flow Logs + Athena + CloudTrail 摸清依赖，把跨 Region 业务切到 VPC Peering + Route53 Private Hosted Zone，再用 SSM Port Forwarding 替代开发者直连，最后原子切换 SG 并清理长尾白名单。每一步都给可直接执行的脚本和 IAM Policy。覆盖 4 个真实踩到的坑。</description><media:content xmlns:media="http://search.yahoo.com/mrss/"

提供了一层统一的访问控制：单台 ECS 跑控制面，每个 K8s 集群部署 Subnet Router Pod，ACL 基于身份控制访问范围。本文给出从阿里云 ECS 创建命令、Caddyfile、完整 Headscale 配置、K8s 完整 manifest、运维脚本、客户端接入脚本到故障 runbook 的一整套可直接复制执行的工件，包含 5 个生产中真实踩到的坑。</description><media:content xmlns:media="http://search.yahoo.com/mrss/" url="https://socake.github.io/playbook/zerotrust-mesh-headscale/featured.jpg"/></item><item><title>Headscale 自建零信任
