Hakoniwa

使用命名空间、资源限制和seccomp进行Linux进程隔离。它通过创建一个新的、完全空的挂载命名空间（根在不可见的主机的tmpfs上），当最后一个进程退出时将自动清理。然后，您可以使用策略配置文件或命令行选项来构建根文件系统和命名空间中的进程环境以及要运行的命令。

安装

Cargo

  • 按照此指南安装libseccomp。
  • 按照此指南安装rust工具链，以便安装cargo。
  • 运行 cargo install hakoniwa-cli。

使用方法

命令行界面

当使用命令行时，hakoniwa-run将加载默认策略配置文件KISS-policy.toml以确保创建一个最小的挂载命名空间，使用--policy-file使用您自定义的版本。
