How to connect a service running inside a docker with consul?

I am trying to run a docker container that takes the CONSUL_URL as an ENV Variable. For now, I have set up the consul on my localhost and I run it like this: consul agent -dev -bind=127.0.0.1 -ui-dir /usr/local/Cellar/consul/0.7.0/share/consul/web-ui

I am able to access the consul ui this way when I go to http://localhost:8500. But, now that I am running the docker container through this, docker run -e CONSUL_URL=127.0.0.1:8500 -p 8500:8500 b321825a6c7a, it gives me the following error: 

2016/10/05 09:38:38 [ERR] (view) "key_or_default(foo.appconfig.properties/logger.name, "foo_PERF_LOG")" store key: error fetching: Get http://127.0.0.1:8500/v1/kv/foo.appconfig.properties/logger.name?stale=&wait=60000ms: dial tcp 127.0.0.1:8500: getsockopt: connection refused
2016/10/05 09:38:38 [ERR] (runner) watcher reported error: store key: error fetching: Get http://127.0.0.1:8500/v1/kv/foo.appconfig.properties/logger.name?stale=&wait=60000ms: dial tcp 127.0.0.1:8500: getsockopt: connection refused
Consul Template returned errors:
store key: error fetching: Get http://127.0.0.1:8500/v1/kv/foo.appconfig.properties/logger.name?stale=&wait=60000ms: dial tcp 127.0.0.1:8500: getsockopt: connection refusedexecuting: 'myscript.sh run'

Why am I not able to connect with the consul URL? I also tried changing the localhost url to the IP Address of my machine, but, I get the same error with that too. I have done the port mapping, so, I guess it should work. Where am I going wrong?

You have to use the --net=host flag. This flag will create sockets for the exposed ports for all interfaces in the main OS.

docker run --net=host -e CONSUL_URL=127.0.0.1:8500  b321825a6c7a
