Docker socket.io - docker

Question

I am trying to run the client from docker so that it connects to my server that is outside the containers but does not connect to me, it only works if I run it locally or if I pass the --netork host parameter, the latter is not valid since I have what to launch multiple containers
This is my code
var client = require('socket.io-client');
var options = {
secure:true,
reconnect: true,
rejectUnauthorized : false,
forceNew : true
};
var socket = client.connect('wss://192.168.1.15:8443',options);
var channel = process.env.SESSION;
var canal_1 = channel+'-1';
var canal_2 = channel+'-2';
socket.on('connect', function(){});
socket.on(canal_1, function(data){
console.log(data)
});
socket.on(canal_2, function(data){
console.log(data)
});
socket.on('disconnect', function(){});
And this is my docker
FROM node:12.13-alpine
RUN apk update && apk add --update alpine-sdk wget libxtst-dev libpng-dev python2 xorg-server-dev
RUN mkdir -p /home/node/app/node_modules && chown -R node:node /home/node/app
WORKDIR /home/node/app
COPY package*.json ./
RUN npm install robotjs
USER node
RUN npm install
COPY --chown=node:node . .
ENTRYPOINT [ "node"]
And this my package.json
{
"name": "nodejs-socket",
"version": "1.0.0",
"description": "nodejs socket",
"author": "Ricardo Jimenez Hurtado <jimenezhurtadoricardo#gmail.com>",
"license": "MIT",

"dependencies": {
"express": "^4.16.4",
"fs": "0.0.1-security",
"https": "^1.0.0",
"socket.io-client": "^2.3.0"
}
}
And this is my run code for docker
docker run -ti -e SESSION=1 node_server client_socket.js
Thanks for all
Best regards

Answer 1

You can achieve what you want here in a number of ways.
The best of which would be to also run your server node in a docker container, and use docker networks to enable communication between the server and clients.

Answer 2

I solve this problem with two steps, first I develop a better code with socket.io and socket.io-client for that the client join to a room and sendo step I revise all my network configuration for that my servername can be find for all my networks device
