Description of problem:

Installing a vanilla OSE 3.5 (and probably 3.6, I haven't tried it yet) as detailed in the documentation causes the installer to fail.

Version-Release number of the following components:

# rpm -q openshift-ansible
openshift-ansible-3.5.145-1.git.0.e1e330f.el7.noarch

# rpm -q ansible
ansible-2.4.1.0-1.el7.noarch

# ansible --version
ansible 2.4.1.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Aug  2 2016, 04:20:16) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]


How reproducible:
Follow the exact same steps in the official documentation for OSE 3.5.

Steps to Reproduce:
1.
2.
3.

Actual results:
ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/usr/share/ansible/openshift-ansible/roles/etcd/tasks/system_container.yml': line 22, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: Install or Update Etcd system container package
  ^ here


The error appears to have been in '/usr/share/ansible/openshift-ansible/roles/etcd/tasks/system_container.yml': line 22, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: Install or Update Etcd system container package
  ^ here

exception type: <class 'ansible.errors.AnsibleParserError'>

An error was detected. After resolving the problem please relaunch the
installation process.

Expected results:
The installer should start installing OCP as below:

Are you ready to continue? [y/N]: y

Play 1/28 (Create initial host groups for localhost)
..
Play 2/28 (Create initial host groups for all hosts)


Additional info:
Instead of depending on ansible provided from the rhel-7-server-extras-rpms, use the ansible package provided from the relavent OSE repository (rhel-7-server-ose-3.5-rpms):

# yum remove ansible
# yum --disablerepo=rhel-7-server-extras-rpms install atomic-openshift-utils
