command : docker run hello-world hangs

[spect...@gmail.com]

HI,

I am setting up Docker development environment following the instruction on docker website.

1. I run the docker container using this command

docker run --privileged --rm -ti -v `pwd`:/go/src/github.com/docker/docker dry-run-test /bin/bash

2. and inside Docker dev container, I run the command

$docker daemon -D

.....

2. On a 2nd terminal, docker run hello-world

root@43d36d0cd4ad:/go/src/github.com/docker/docker# docker run hello-world

but it never  returns to the command line.


please help with what could be the issue here.

I have some understanding on using/runing Docker but very new to Docker development.
