I have a very simple “Hello world” server that i wrote in RUST, the program is running correctly locally (not as an image), cargo run

Here is my main.rs file –

use axum::{routing::get, Router};
use std::net::SocketAddr;
use tracing_subscriber;

#[tokio::main]
async fn main() {
    let app = Router::new().route("/", get(|| async { "Hello, world!" }));

    let addr = SocketAddr::from(([0, 0, 0, 0], 3000));
    tracing::debug!("listening on {}", addr);

    axum::Server::bind(&"0.0.0.0:3000".parse().unwrap())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

here is my dockerfile that was generated using docker init

Whenever i run the image, ill get 2024-07-10 12:23:01 Hello, world! and the container will shut down.
