在虚拟docker-machine中运行NodeJS服务器-无法访问正在运行的VM应用

Question

I am going through this docker tutorial in order to get my electrode app working in a VM.

When I run node server.js in the VM it logs a message indicating the Hapi server is running:

Hapi.js server running at http://10cc6b467731:3000

However, when I try to navigate to http://10cc6b467731:3000 in my browser I am unable to access the app.

My initial thought was that the port forwarding is messed up. I went into my VirtualBox configs for this VM, but it still does not work:

I also included port forwarding in my docker-compose.yml file, but to no avail:

chat:
  build: .
  ports:
    - '3000:3000'
  volumes:
    - .:/home/app/chat
    - /home/app/chat/node_modules

Now I am questioning if this is even a port forwarding issue at all. I am new to Docker and configuring VM's so I am not sure what direction to go in to continue troubleshooting this. What steps can I perform to confirm this is a port forwarding issue?

You need to allow all IPs in node.js server code

add code like listen(3000, "0.0.0.0"); in your node server.js
