ansible_version ignored if Ansible already in docker container

[alex-harvey-z3q]

It appears that if the provisioned Docker container already contains Ansible, the ansible_version flag is ignored:

My .kitchen.yml:

---
driver:
  name: docker

platforms:
  - name: centos-7.2
    driver_config:
      image: ansible/centos7-ansible:stable
      platform: centos
      provision_command:
        - yum -y install iproute
        - yum -y install net-tools
      forward:
        - 8082:8082

provisioner:
  name: ansible_playbook
  hosts: test-kitchen
  ansible_verbose: false
  ansible_verbosity: 2
  require_ansible_repo: false
  require_ansible_omnibus: true
  ansible_version: 1.9.6
  require_chef_for_busser: false
  requirements_path: requirements.yml
  extra_vars:
    java_packages: ['java-1.8.0-openjdk']

verifier:
  name: serverspec

suites:
  - name: default
    verifier:
      patterns:
        - roles/ansible-nexus/test/integration/default/serverspec/default_spec.rb
      bundler_path: '/usr/local/bin'
      rspec_path: '/usr/local/bin'

what should we do?
add extra code in the script that if which ansible is true then do an ansible -v and then check the version matches if not error message an exit?
versioning ansible is not that useful when installing apt-get or yum as you basically have to take the version they have. More useful when building from source.

Perhaps it would be valid then to just error out with some advice to the user on what should do if they need to test their code against a matrix of ansible versions?

[steenzout]

how about using virtualenvs and always guarantee you are using a clean environment using the Ansible version you requested?

I can provide a patch for this if this is something you would be interested.

i will also take in PR requests and try and make the code as flexible as possible.
