Linux 环境下管理控制组的 Rust 库

手册

• libgroup
• cgroup_v1
• cgroup_v2

用法

Toml 包

[dependencies]
log = "*"
env_logger = "*"
libcgroup_rs = {version = "*"}

Rust 代码

fn main()->Result<(),std::io::Error>{
    
    env_logger::try_init()?;

    // Initialize
    CGroup::init()?;
    info!("Mount Point = {:?}",CGroup::get_subsys_mount_point("cpu"));

    // create cgroup container
    let container_name = "container_test_work";
    let mut cg = CGroupBuilder::new(container_name)?;
    info!("Add Controller = {:?}",cg.add_controller("cpu")?);
    info!("Get Controller = {:?}",cg.get_controller("cpu")?);
    //cg.free_controllers();

    //only root
    cg.create(0)?;

    // execute shell
    cg.attach_task_shell()?;

    Ok(())
}

结果

1:cpu:/foo

由 CGroup 创建的资源被使用
