Denys all connections when running in docker

[tacyarg]

If you listen using "localhost" in docker the app will refuse all inbound connections.

BEFORE:
app.listen('localhost', 2002, () => {
    console.log("FUCK")
})

AFTER:
app.listen('*', 2002, () => {
    console.log("FUCK")
})

Just thought i'd save someone else an entire day debugging this torturous problem.
Now the docker container works properly.

You can also just do app.listen(2002). If you want to bind to any one interface you have to make sure you actually have that interface up, using something like ifconfig

I had the same issue!
I just did:

const PORT = 3000
app.listen('::', PORT, token => {
  debug.info(token ? `Server listening on port ${PORT}` : `Failed to listen to port ${PORT}`)
})

Now, the container is listening the IP and PORT correctly...

~/app $ netstat -plnt
