ansible中docker 代理设置

SUMMARY

I'm trying to build a Dockerfile behind proxy using docker client config.json as described here.
Ansible docker_image default path for config.json is different that the one for docker client:
Docker docs: ~/.docker/config.json
Ansible docs: ~/docker/config.json

Trying to use DOCKER_CONFIG doesn't solve the problem:

$ echo DOCKER_CONFIG=/root/.docker >> /etc/environment
$ sudo su -
$ echo $DOCKER_CONFIG
/root/.docker

Links don't solve the problem:

# config.json for non privileged user in place
$ cat /home/tester/.docker/config.json
# config.json for root as we use become
# cat /root/.docker/config.json

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://myproxy.com:8080",
     "httpsProxy": "http://myproxy.com:8080",
     "noProxy": "127.0.0.1"
   }
 }
}

# adding a link
# ln -s .docker docker
# cat /root/docker/config.json
{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://myproxy.com:8080",
     "httpsProxy": "http://myproxy.com:8080",
     "noProxy": "127.0.0.1"
   }
 }
}

STEPS TO REPRODUCE

$ cat Dockerfile

FROM ubuntu:16.04
RUN apt-get -y update
RUN apt install -y rsync

$ cat inventory

localhost

$ cat playbook.yml

---
- hosts: localhost
  tasks:
    - become: yes
      docker_image:
        path: .
        name: aptupdate:latest

EXPECTED RESULTS

Ansible docker_image should successfully build a Dockerfile

ACTUAL RESULTS

Ansible docker_image skips docker client config.json and the Dockerfile timeouts without proxies.

$ ansible-playbook -i inventory playbook.yml -v
