I have started a docker container using the command 

sudo docker run -it -P -d plcdimage

The image is built using a Dockerfile which has instruction EXPOSE 8080. Container runs a jboss server with an application deployed on it. Port mappings are :

Command: sudo docker port be1837e849dc

Output: 8080/tcp -> 0.0.0.0:32771

When I try to access the web application running on jboss in the container from the mapped host port using url:

http://IPAddressOfHost:32771/

I get connection refused error. Following is the result of command "netstat -tulpn"

I tried doing telnet hostip 32771 and it also results in connection refused.

Docker version 1.12.1  
build 23cf638

What could be the possible reason for this?

Thanks in advance

    First thing to check is if your container is actually listening on port 8080. You can get the IP address of your container with `docker inspect`, and try browsing from the host to `http://[container-ip]:8080` – Elton Stoneman Oct 25 '16 at 08:52

    What is the result of `sudo docker ps`? – Rao Oct 25 '16 at 10:21

I found that jboss server running inside the container was not listening on 0.0.0.0. One option to do this is, while starting the standalone server use -b 0.0.0.0.

/bin/standalone.sh -b 0.0.0.0
