Error saying KeyError ApiVersion - Ansible

Question

I'm getting the following error:

failed: [demo.com] => {"failed": true, "item": "", "parsed": false}
invalid output was: Traceback (most recent call last):
  File "/root/.ansible/tmp/ansible-tmp-1400951250.7-173380463612813/docker", line 1959, in <module>
    main()
  File "/root/.ansible/tmp/ansible-tmp-1400951250.7-173380463612813/docker", line 693, in main
    containers = manager.create_containers(1)
  File "/root/.ansible/tmp/ansible-tmp-1400951250.7-173380463612813/docker", line 548, in create_containers
    if docker.utils.compare_version('1.10', self.client.version()['ApiVersion']) < 0:
KeyError: 'ApiVersion'

I'm using Ansible version 1,7 and docker version 0.9.1

The reason behind this error is that the older version of docker does not have the ApiVersion specified. 

The only thing you can do is update your docker version. Follow these commands:

$ sudo apt-get install -y python-pip
$ sudo pip install docker-py
