Describe the bug

SIGINT does not pass to container

To reproduce

Build the following

import { setTimeout } from "timers/promises";

const b = async () => {
	console.log("IN");
	process.on("SIGINT", () => {
		console.log("[ ⚡️ ] SIGINT received, shutting down");
	});

	process.on("SIGTERM", () => {
		console.log("[ ⚡️ ] SIGTERM received, shutting down");
	});

	process.on("uncaughtException", (err) => {
		console.log("[ ⚡️ ] Uncaught exception", err);
	});
	
	console.log("Loop init'd. Waiting...");
	await setTimeout(5000000);
}

b()

Run it

Try to SIGINT it

Expected behavior

SIGINT is processed

Environment

All environments

Seems to be because we have a /bin/bash entrypoint

Unable to reproduce this. The SIGINT signal is, in fact, passed to the container upon running the example provided by @JakeCooper in the issue description.

I'm using Docker v4.26.1 on MacOS Monterey on an ARM macbook.
Could you provide a more definitive way to reproduce this? What platform are you testing on, and what docker version are you using?
