Container Diff
Container-diff 是一个命令行工具，旨在检查和比较容器镜像的内部组成。它作为容器化环境的审计器，提供对文件系统结构、已安装软件包和单个镜像或两个不同构建之间配置元数据的可见性。
该工具通过其跨容器层执行细粒度分析的能力脱颖而出，允许用户追踪构建历史并识别特定的配置漂移。通过支持注册表无关的镜像获取和模块化分析驱动程序，它集成到各种工作流中，以验证软件供应链的一致性并排查构建时错误。
除了基础检查外，该工具还提供全面的报告功能，包括为自动化监控和性能审计生成结构化输出的能力。它支持远程注册表身份验证，以促进对私有镜像的安全访问，确保可以在各种部署环境中执行审计。
Features
