Program doesn't exit on SIGINT or SIGTERM

[hardcore-sushi]

When I run see and press CTRL+C (SIGINT) to stop it, it doesn't exit. Even a SIGTERM signal doesn't stop the process. The only way to stop see is to kill it.

It would be nice if see could handle this signals and exit gracefully.

Normally it should exit the process because he is not handling any signals and daemons, what OS are you using?

Oh sorry you're right. It only happens when used in docker, but only when started directly (not using a shell), such as with CMD or ENTRYPOINT instructions. I have the issue with my custom Dockerfile as well as your own. Very strange, maybe a docker issue. However I successfully patched your code so it exits when receiving SIGINT or SIGTERM:

src/main.rs:

+use tokio::signal::unix::{signal, SignalKind};
 
Line 66:
-    bind_tcp(configs).await;
+    tokio::spawn(async move {
+        bind_tcp(configs).await;
+    });
+    let mut sigint = signal(SignalKind::interrupt()).unwrap();
+    let mut sigterm = signal(SignalKind::terminate()).unwrap();
+    tokio::select! {
+        _ = sigint.recv() => println!("SIGINT"),
+        _ = sigterm.recv() => println!("SIGTERM")
+    }

With this patch, the docker container exits with SIGINT when pressing CTRL+C and with SIGTERM when using docker stop.
