Ansible playbooks break since version 1.12.2-rc1, build 45bed2c

Hi,

Since the latest beta release Docker 1.12.2-rc1, Ansible’s service module ins’t capable of starting Nginx and hangs on the task… I can make the exact playbook work while running the stable version of Docker version 1.12.1

To reproduce:

Create a playbook play.yml:

---
- hosts: webservers
  gather_facts: false

  tasks:
    - apt:
        name: nginx
        state: installed

    - service: name=nginx state=started enabled=yes

Create an inventory:

[webservers]
nginxweb ansible_connection=docker

Create the container:

docker run -dit --name nginxweb williamyeh/ansible:ubuntu16.04 /bin/bash

Result:

docker --version
Docker version 1.12.2-rc1, build 45bed2c, experimental
ansible --version
ansible 2.1.2.0

ansible-playbook -i inventory play.yml

PLAY [webservers] **************************************************************

TASK [apt] *********************************************************************
changed: [nginxweb]

TASK [service] *****************************************************************
HANGS HERE

At that point if I connect to the container and check Nginx’s status, I can see it being started. If I trigger the service restart service nginx restart then Ansible will finish the play. I am pretty sure it has nothing to do with Ansible since the Docker stable version gives:

Create the container:

docker run -dit --name nginxweb williamyeh/ansible:ubuntu16.04 /bin/bash

Result:

docker --version
Docker version 1.12.1, build 6f9534c
ansible --version
ansible 2.1.2.0

ansible-playbook -i inventory play.yml

PLAY [webservers] **************************************************************

TASK [apt] *********************************************************************
changed: [nginxweb]

TASK [service] *****************************************************************
changed: [nginxweb]

PLAY RECAP *********************************************************************
nginxweb                   : ok=2    changed=2    unreachable=0    failed=0

Let me know if you need anything else.

Cheers,
