rust-cni

This is the CNI plugin impl by rust for container-runtime create CNI network.

requirements

• Install cni plugin in /opt/cni/bin
• Prepare cni config in /etc/cni/net.d

Run test

run it as root.

cargo test --test it_test --  --test-threads=1 --nocapture

example

use std::{fs::File, io};
use rust_cni::cni::Libcni;
use netns_rs::NetNs;
use nix::sched::setns;

fn create_ns() -> Result<NetNs, String> {
    let ns = NetNs::new("ns_name").unwrap();
    println!("{:?}", ns.path());
    Ok(ns)
}

fn main() {
    let ns = create_ns().unwrap();
    // Default cni config is in /etc/cni/net.d/
    // Default cni bin is in /opt/cni/bin/  
    let mut cni = Libcni::default();
    cni.load_default_conf();
    cni.add_lo_network().unwrap();

    let id = "test".to_string();
    let path = ns.path().to_string_lossy().to_string();
    cni.setup(id.clone(), path.clone()).unwrap();

    println!("try to remove --------------------");
    cni.remove(id.clone(), path.clone()).unwrap();
    ns.remove().unwrap();
}
