Description of problem: ... TASK [openshift_facts : set_fact] ********************************************** ok: [master01.example.com] ok: [node01.example.com] TASK [openshift_facts : Ensure PyYaml and yum-utils are installed] ************* ok: [master01.example.com] => (item=[u'PyYAML', u'yum-utils']) ok: [node01.example.com] => (item=[u'PyYAML', u'yum-utils']) TASK [openshift_facts : Gather Cluster facts and set is_containerized if needed] *** An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ImportError: No module named six fatal: [master01.example.com]: FAILED! => { "changed": false, "failed": true, "module_stderr": "Traceback (most recent call last):\n File \"/tmp/ansible_Nhdmp7/ansible_module_openshift_facts.py\", line 29, in <module>\n from six import string_types\nImportError: No module named six\n", "module_stdout": "" } MSG: MODULE FAILURE Manually installing python-six and rerunning allows installation to continue. Version-Release number of selected component (if applicable): openshift-ansible-3.4.56-1.git.0.7ba9968.el7.noarch
python-six will be installed as dependency of ansible, if you are using our official ansible. # rpm -q ansible ansible-2.2.0.0-1.el7.noarch # rpm -qR ansible|grep six python-six So this should be NOTABUG.
This is about the target nodes being installed, not about the bastion host initiating the installation. Thanks.

Tested with origin openshift-ansible-3.4.63-1 1) make sure the packages aren't installed into the RHEL image. iproute is depended by many other packages (NetworkManager, yum-rhn-plugin, etc) so I didn't remove it. # rpm -qa |grep "iproute\|python-dbus\|python-six\|PyYAML\|yum-utils" iproute-3.10.0-74.el7.x86_64 2) Trigger the installation with that image 3) Installation succeed and works well Will test again when openshift-ansible-3.4.63-1 is in puddle.
Verified with rpm package openshift-ansible-3.4.63-1.git.0.54f8923.el7.noarch
