Why the expected message wasn't print to console output?

Question

Here I asked the question about SIGTERM and I get the answer: Windows can't emit this signal. But I geet the same problem for Linux (I wrote new code example)... I build the linux docker image on the base of node:14.14.0-alpine3.10:

My Dockerfile:

FROM node:14.14.0-alpine3.10
WORKDIR /opt/app/
COPY . .
RUN npm i
CMD npm run start

My .dockerignore file:

node_modules/

My src/index.js file:

// Build the image and start its container:
// docker build -t my-app .
// docker run -it --rm --name my-app my-app

const appArgs = require("minimist")(process.argv.slice(2));
const readline = require("readline").createInterface({
    input: process.stdin,
    output: process.stdout,
});
const signalName = "SIGTERM";

process.on(signalName, () => {
    console.log(`${signalName} happened.`); // I don't see this message. Why?
});

console.log("application args: %o", appArgs);

let name = null;
let age = null;
readline.question("Name: ", answer => {
    name = answer;
    readline.question("Age: ", answer => {
        age = answer;
        readline.close();
        printHello();
    });
});

function printHello() {
    console.log(`Hello, ${name} (${age} age)`);
    process.kill(process.pid, signalName);
}

My package.json file:

{
  "name": "app",
  "version": "1.0.0",
  "description": "",
  "main": "src/index.js",
  "scripts": {
    "start": "node src/index.js -abc --def --ghj 'Bob' -- 11 22 33"
  },
  "keywords": [],
  "author": "Andrey Bushman",
  "license": "ISC",
  "dependencies": {
    "minimist": "^1.2.5"
  }
}

I built my linux based image and run its container on Windows:

docker build -t my-app .
docker run -it --rm --name my-app my-app

The console output:

PS C:\Users\bushm\source\repos\node_sandbox\app> docker run -it --rm --name my-app my-app

> [email protected] start /opt/app
> node src/index.js -abc --def --ghj 'Bob' -- 11 22 33

application args: {
  _: [ '11', '22', '33', [length]: 3 ],
  a: true,
  b: true,
  c: true,
  def: true,
  ghj: 'Bob'
}
Name: Bob
Age: 30
Hello, Bob (30 age)
PS C:\Users\bushm\source\repos\node_sandbox\app>

My program was launched by Linux instead of Windows. Why "SIGTERM happened." string didn't appear in the console output at this time?
