Docker build not working

[JigarS91]

Hi,

I am reading the book and now on Chapter 2. As suggested I have followed the steps and created a dockerfile and app.js files.

Whenever I try to build the image it just hangs and does not proceed ahead.

Below is the Dockerfile content: -

FROM node:7
ADD app.js /app.js
ENTRYPOINT ["node", "app.js"]

Below is the app.js file content: -

const http = require('http');
const os = require('os');
console.log("Kubia server starting...");
var handler = function(request, response) {
console.log("Received request from " + request.connection.remoteAddress);
response.writeHead(200);
response.end("You've hit " + os.hostname() + "\n");
};
var www = http.createServer(handler);
www.listen(8080);

Jigars-MacBook-Pro:~ jigars$ docker build -t kubia:latest -f Dockerfile .

It doesn't go ahead from here. Not sure what is the issue. I don't find the image when I run docker images.

docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
busybox latest e1ddd7948a1c 2 weeks ago 1.16MB
node 7 d9aed20b68a4 12 months ago 660MB

Let me know what am I missing. Awaiting reply at the earliest.

@JigarS91 Did you manage to get this working? Because there seems to be no issue using the code from chapter 2:

$ docker build -t kubia:latest -f Dockerfile .

Possibly a Docker issue but more info is needed.
