Title: Admin endpoint not responding

Description:

Just to start with I am new to envoy. From getting started example I am able to get envoy to proxy all outgoing calls. Now I am trying to get stats and metrics from envoy using the admin endpoint such as /stats.

When I "curl -v localhost:9901/stats" Get the following:

*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 9901 (#0)
> GET /stats HTTP/1.1
> Host: localhost:9901
> User-Agent: curl/7.54.0
> Accept: */*
>
* Empty reply from server
* Connection #0 to host localhost left intact
curl: (52) Empty reply from server

Also when I try to connect to via chrome on localhost:9901/stats same response come back. My guess admin server is not being instantiated when starting docker. Not sure if this is the right approach.

[monubamb]

@monubamb

address: 127.0.0.1
port_value: 9901

My address was binded to loop back address. Changing 0.0.0.0 worked
