Local hackage-server build in docker does not respond

I am trying to install and run a local hackage-server to maintaining private packages. I have followed instruction from https://github.com/haskell/hackage-server/blob/master/Dockerfile:

Usage:

```
Build the container
$ docker build . -t siddhu/hackage-server

Shell into the container
$ docker run -it -p 8080:8080 siddhu/hackage-server /bin/bash

Run the server
Docker> # hackage-server run --static-dir=datafiles
```
At the end I got this:
`hackage-server: Ready! Point your browser at http://127.0.0.1:8080`
But it does not respond in browser or curl. Am I missing something?
