4.1. 安全性

沙盒容器不支持 SELinux 多类别安全标签
当您在容器安全上下文中设置 SELinux Multi-Category Security (MCS)标签时，pod 不会启动。pod 日志中显示以下错误：
Error: CreateContainer failed: EACCES: Permission denied: unknown
Error: CreateContainer failed: EACCES: Permission denied: unknown
在创建沙盒容器时，运行时无法访问容器的安全上下文。这意味着 virtiofsd 没有使用适当的 SELinux 标签运行，且无法访问容器的主机文件。因此，您无法依赖 MCS 标签来基于每个容器隔离沙盒容器中的文件。这意味着所有容器都可以访问沙盒容器中的所有文件。目前，这个问题还没有临时解决方案。
