Docker cannot connect to the host machine

Question

Im trying to set up a connection between my Docker container and my host that it is run on. Ive read Access host database from a docker container , and added the host ip to the hostfile of the Docker container, however it still will not respond to pings.

Im hosting my servers on an AWS box, and the ports 80, 8080 are open.

How can I get the host sever to respond to pings from the container?

Thanks.

You can run Docker container using "--net=host" option, then the container will share the same network namespaces with the host node.

For example:

sudo docker run -it --net=host ubuntu:14.04 bash
