Running a receiver application on a PC

To run a receiver app on a PC, follow this sequence:

1. Create the receiver folder.
2. Create the ./receiver/package.json file with the following content:

{
  "name": "receiver",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node index.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
 }

3. Create the ./receiver/index.js file with the following content:

var http = require('http');
 var querystring = require('querystring');
 
 http.createServer(function (req, res) {
  req.on('data', function (chunk) {
    var data = querystring.parse(chunk.toString());
    console.log(data);
  });
  req.on('end', function () {
    res.writeHead(200, 'OK', {'Content-Type': 'text/html'});
    res.end('Data received.')
  });
 }).listen(8080);

4. Create the ./receiver/Dockerfile file with the following content:

FROM node:boron-onbuild
 EXPOSE 8080

5. Navigate to ./receiver.
6. Build an image and run a Docker container:

# Build an image from a Dockerfile
docker build -t http-receiver .

# Run container in foreground
docker run -p 8080:8080 -it --rm --name http-receiver-container http-receiver

# Run container in background
# docker run -p 8080:8080 -d --rm --name http-receiver-container http-receiver

# Fetch the logs of a container
# docker logs -f http-sensor-container

# Stop running container
# docker stop http-receiver-container
