Docker-无法从外部访问docker端口

Question

So i created a new EC2 Instance and installed docker on it.

I deployed code from ( https://github.com/commonsearch/cosr-front/blob/master/INSTALL.md ) and followed install instructions.

Install was successfull and i started the server:

[ec2-user@ip-172-30-0-127 cosr-front]$ make docker_devserver
docker run -e DOCKER_HOST --rm -v "/home/ec2-user/cosr-front:/go/src/github.com/commonsearch/cosr-front:rw" -w /go/src/github.com/commonsearch/cosr-front -p 9700:9700 -i -t commonsearch/local-front make devserver
mkdir -p build
go build -o build/cosr-front.bin ./server
GODEBUG=gctrace=1 COSR_DEBUG=1 ./build/cosr-front.bin
2016/05/28 16:32:38 Using Docker host IP: 172.17.0.1
2016/05/28 16:32:38 Server listening on 127.0.0.1:9700 - You should open http://127.0.0.1:9700 in your browser!

Well, now when i want to access it from outside, i cant! Not even curl the local server.

When i run docker ps it gives me correct port forwarding:

[ec2-user@ip-172-30-0-127 ~]$ docker ps

These are my docker images:

I have tryed disabling ipv6 and all kind of nonsense google offered me, but without success.

Any ideas ?

EDIT:

Also, if i enter the docker container for frontend( using docker exec ), then I CAN PING AND CULR the frontend.

But i cant from the outside( nor ssh, not from my home pc using browser ).

Also my docker version:

Client:
 Version:      1.9.1
 API version:  1.21
 Go version:   go1.4.2
 Git commit:   a34a1d5/1.9.1

Server:

 Go version:   go1.4.2
 Git commit:   a34a1d5/1.9.1

Answer 1

I made a issue at github as swell and one guy saved the day.

Here's he's response:

Server listening on 127.0.0.1:9700 Your application is listening on localhost. localhost is scoped to the container itself. Thus to be able to connect to it, you would have to be inside the container. To fix, you need to get your application to listen on 0.0.0.0 instead.
