## 新增功能 ### 1. 生产级镜像预热脚本 - **preheat-images-pro.sh**: 修复所有旧版问题的生产级预热脚本 - 基于退出码判断成功（不再依赖 grep 输出） - 自动重试机制（最多3次，间隔递增） - 修正所有镜像路径（使用正确的项目名） - 使用 Robot 账号（移除硬编码密码） - 移除 ELK 镜像（使用 Loki 替代） - 超时保护（每个镜像最长5分钟） - 详细错误报告（JSON 格式输出） - **PREHEAT-GUIDE.md**: 完整的镜像预热使用指南 - 分组预热支持（k8s/monitoring/loki/tempo/otel/database/base） - 性能对比和最佳实践 - 常见问题排查 ### 2. Registry Mirrors 配置 - **configure-containerd-mirrors.sh**: 配置 OrbStack containerd 使用 Harbor 作为多 registry 的 mirror - 支持 docker.io、registry.k8s.io、quay.io、ghcr.io - 自动创建 hosts.toml 配置文件 - K8s YAML 可使用标准路径，自动通过 Harbor 拉取 - **REGISTRY-MIRRORS-SUCCESS.md**: 配置成功验证和使用说明 - 性能提升验证（3.3倍加速） - 工作原理说明 - 维护指南 ## 测试结果 - 预热 23 个核心镜像（K8s + 监控 + 日志）成功率 100% - Registry mirrors 配置后，标准路径拉取速度提升 3.3 倍 - 所有配置文件已移除硬编码密码，使用环境变量 ## 相关文件 - preheat-images-pro.sh（主脚本） - preheat-images-v2.sh（中间版本） - PREHEAT-GUIDE.md（使用指南） - configure-containerd-mirrors.sh（Registry mirrors 配置） - REGISTRY-MIRRORS-SUCCESS.md（配置验证） - preheat-report-20251213-122836.json（预热报告） 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
