Description Ken Dreyer (Red Hat) 2016-05-04 15:26:41 UTC 
Description of problem:
When ceph-installer tries to run Ansible on Xenial cluster nodes, these nodes might not have Python 2.7 installed, so Ansible will fail.

Version-Release number of selected component (if applicable):
ceph-installer-1.0.6

How reproducible:
always

Steps to Reproduce:
1. Install a minimal version of Xenial (for example, an Ubuntu Xenial cloud
   image)
2. Verify that the minimal version of Xenial does not have the "python" package
   present.
3. Proceed with the installation as normal:

 - Run the bootstrap script on the node (for example `curl
   http://installer-node:8181/setup/ | bash`)

 - Next, try to manage the node with ceph-installer (for example, POST to curl
   http://installer-node:8181/api/mon/install to install the ceph-mon software
   on the Xenial node, or any other Ansible action)


Actual results:
Ansible will fail because Python 2 is not present.

Expected results:
ceph-installer is able to manage Xenial nodes with Ansible, and the administrator does not need to manually install "python" on the Xenial nodes ahead of time.

Additional info:
The fix will be to have the bootstrap script explicitly ensure that Python 2 is present for Ansible to use. https://github.com/ceph/ceph-installer/pull/144
