docker module requirements met, but ansible misses docker-py

[Goetz Leupold]

Hello everybody,

got 2 Servers with docker and ansible requirements to manipulate them. But at server B , ansible doent find docker-py allthough it is installed. The versions of the installed softwares differ, so i guess there is the problem.

Server A(working):
python2.7
docker_py-1.7.2.egg-info
Server:
 Version:      1.10.3
 API version:  1.22
 Go version:   go1.5.3
 Git commit:   20f81dd
 Built:        Thu Mar 10 15:48:06 2016
 OS/Arch:      linux/amd64

Server B(not working):
python2.7
docker_py-1.8.0.egg-info
Server:
 Version:      1.9.1
 API version:  1.21
 Go version:   go1.4.3
 Git commit:   a34a1d5
 Built:        Fri Nov 20 17:56:04 UTC 2015
 OS/Arch:      linux/amd64

If i try then to start a container through ansible i got the error:
fatal: [HOST]: FAILED! => {"changed": false, "failed": true, "msg": "`docker-py` doesn't seem to be installed, but is required for the Ansible Docker module."}

Any ideas? If you need more specific information let me know and excuse my bad english :D

Greetings,

Hi, 

I have the same issue. 

Any solution ?

You are probably not executing the same version of python that has docker-py installed.

Hey did you figure it out. I have the same problem: specs below:

pip -V

pip 8.1.2 from /usr/lib/python2.6/site-packages (python 2.6)

pip freeze |grep docker

DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

docker-compose==1.7.1

docker-py==1.8.1

dockerpty==0.4.1

error message below: 

: FAILED! => {"changed": false, "failed": true, "msg": "`docker-py` doesn't seem to be installed, but is required for the Ansible Docker module."}

Found a work around, by adding specifics of pip and docker-py to the playbook

---

- name: install pip

  yum: name=python-pip state=latest

- name: work around docker-py

  pip:

    executable=/usr/local/bin/pip

    name=docker-py

    state=present

    version=1.8.1
