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 –
<code>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();
}
</code>
<code>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.

Not sure what’s wrong on your end, but on my machine your code works differently than what you described.
main.rs and Cargo.toml are the same, I modified Dockerfile slightly:
<code>ARG RUST_VERSION=1.70.0
ARG APP_NAME=rust-image
FROM rust:${RUST_VERSION}-alpine AS build
RUN apk add --no-cache clang lld musl-dev git
WORKDIR /app
COPY src /app/src
COPY Cargo.toml /app
ARG APP_NAME
RUN cargo build --release &&
cp ./target/release/axum-project /bin/server
FROM alpine:3.18 AS final
ARG UID=10001
RUN adduser
--disabled-password
--gecos ""
--home "/nonexistent"
--shell "/sbin/nologin"
--no-create-home
--uid "${UID}"
appuser
USER appuser
COPY --from=build /bin/server /bin/
EXPOSE 3000
CMD ["/bin/server"]
</code>
<code>ARG RUST_VERSION=1.70.0
ARG APP_NAME=rust-image
FROM rust:${RUST_VERSION}-alpine AS build
RUN apk add --no-cache clang lld musl-dev git
WORKDIR /app
COPY src /app/src
COPY Cargo.toml /app
ARG APP_NAME
RUN cargo build --release &&
cp ./target/release/axum-project /bin/server

--uid "${UID}"
appuser
USER appuser

</code>
ARG RUST_VERSION=1.70.0
ARG APP_NAME=rust-image

Then:
<code>cd /path/to/project
docker build -t foo .
docker run -it --rm -p 3000:3000 foo
</code>
<code>cd /path/to/project
docker build -t foo .
docker run -it --rm -p 3000:3000 foo
</code>
cd /path/to/project
docker build -t foo .
docker run -it --rm -p 3000:3000 foo
in another terminal:
<code>curl localhost:3000
</code>
<code>curl localhost:3000
</code>
curl localhost:3000
each time I do curl I get Hello world back.
