Simulation "docker build -f" with ansible module "docker_image"

While I build docker image and I want to add the instruction "COPY" in Dockerfile with a directory which is outside of current build directory(place where Dockerfile is placed) - I'm using something like this:

docker build -f centos6-fresh/Dockerfile -t test/c6-fresh .

Now I want to do provisioning containers and building docker images through ansible. Of course I'm able to do it with shell, command or raw modules, but I saw special module for Docker.

So I've used module "docker_image"

- name: Build test image
       docker_image:
           path: /docker/build_env/test
           name: test_build
           tag: v0

And certainly I've got the error.

Is there any option, to set from which directory, building process must be started?

UPD The example of case where I need these manipulations:

I have management node(my laptop) with ansible and Docker host with containers. Ansible dir is provisioning with git to Docker server.

Usually I build an image in the directory build_env on the Docker host:

[root@docker build_env]# ls -1
ansible
centos6-fresh
centos7-fresh
debian8-fresh
templates
test

So after run "git pull" in ansible directory, I run something like

docker build -f centos6-fresh/Dockerfile -t test/c6-fresh .

Dockerfile consists:

COPY ansible /etc/ansible

As we now, docker prevents to use something like "COPY ../ansible" in the COPY or ADD options.

According to the docker_image documentation, there is a dockerfile option that is an exact analog to the -f command line option. So you would just need:

- name: Build test image
  docker_image:
    path: /docker/build_env/
    name: test_build
    tag: v0
    dockerfile: centos6-fresh/Dockerfile
