Tiny CE 的规范

支持的操作

• fn create(id: &String, bundle: &String)
• fn start(id: &String)
• fn delete(id: &String)

用例:

use chrono;
use std::{thread, time::Duration};
use tiny_ce::{create, delete, start};

fn main() {
    let datetime = chrono::offset::Local::now();
    let container_id = format!("container-centos-{}", datetime.format("%m%d-%H%M%S"));
    let bundle = "./test/centos".to_string();

    create(&container_id, &bundle); // 创建容器
    start(&container_id); // 启动容器

    // Runtime 进程睡眠 5 秒
    thread::sleep(Duration::from_millis(5000));

    delete(&container_id); // 删除容器
}
