Dial tcp: lookup localhost on [::1]:53: dial udp [::1]:53: socket: operation not permitted

hi,
I have one application which run successfully in pure ubuntu file system.
then, I tar this ubuntu root file system and import it to docker image, then run the docker image.
however, when I run my application in docker container, I got the below error:
Post http://localhost:8000/2016-11-01/cloudwatch/logs/: dial tcp: lookup localhost on [::1]:53: dial udp [::1]:53: socket: operation not permitted

I searched this issue via google, but I don’t find the solution.
Appreciate for any cue how to fix this issue!
thanks a lot.

below is the sequency to setup docker image and container:

  1. tar the root file system (for example: rootfs.ggc.tar) in which the application can run successfully
  2. import this tar archive to docker image:
    cat rootfs.ggc.tar | docker import - docker.ggc
  3. get the image ID (for example: 845283a6bc4f) with command “docker images”
  4. run docker container with below command (for example: 845283a6bc4f):
    docker run --privileged -ti 845283a6bc4f /bin/bash
  5. now enter the container prompt, start the application.

below is my docker information:
