Description of problem:

Failed to get value from vars_files of ansible

Version-Release number of selected component (if applicable):
ansible: 2.3.1.0
python-shade: 1.22.2 

How reproducible:

Steps to Reproduce:

1.Prepare credential yaml file (openrc.yml) for OpenStack. eg

OS_AUTH_URL: https://test-tenant:5000/v2.0
OS_TENANT_ID: c6ca0969da0141e3a62e23eccab4a190
OS_TENANT_NAME: "test-tenant"
OS_USERNAME: 'user'
OS_PASSWORD: 'password'

2.Define external variable file in playbook 

vars_files:
 -  "{{ playbook_dir }}/env/openrc.yml"

3.ansible-playbook execute

Actual results:

Although OS_* values are set, It failed to execute command. 

The full traceback is:
Traceback (most recent call last):
  File "/tmp/ansible_kC8ycr/ansible_module_os_server.py", line 648, in <module>
    main()
  File "/tmp/ansible_kC8ycr/ansible_module_os_server.py", line 633, in main
    cloud = shade.openstack_cloud(**cloud_params)
  File "/usr/lib/python2.7/site-packages/shade/__init__.py", line 109, in openstack_cloud
    cloud_config = config.get_one_cloud(**kwargs)
  File "/usr/lib/python2.7/site-packages/os_client_config/config.py", line 1071, in get_one_cloud
    auth_plugin = loader.load_from_options(**config['auth'])
  File "/usr/lib/python2.7/site-packages/keystoneauth1/loading/base.py", line 162, in load_from_options
    raise exceptions.MissingRequiredOptions(missing_required)
keystoneauth1.exceptions.auth_plugins.MissingRequiredOptions: Auth plugin requires parameters which were not given: auth_url

    "module_stdout": "",
    "msg": "MODULE FAILURE",
    "rc": 0
}

After hostvars environment set, It succeed

Expected results:

I think shade should set variable from vars_files

Comment 1 Lars Kellogg-Stedman 2017-07-11 13:48:15 UTC

This appears to be an ansible issue, not a shade issue. 

The os_server module doesn't look for *ansible* variables named OS_*, it looks for *environment* variables named OS_AUTH_URL, etc.  Otherwise, you need to provide the module with authentication information in the 'auth' parameter.

Alternatively, you can place your authentication in clouds.yaml file and use the 'cloud' parameter to the module.

This information is available in the documentation for the os_server module at http://docs.ansible.com/ansible/os_server_module.html.
