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
