add ansible example

Since running the bootstrap.py can take quite a while, I'd suggest the addition of a "stat" module call and only run the bootstrap.py if the client does NOT have a .pem file. The bootstrap.py uses this file as a signal to exit but doing this in Ansible eliminates the Python interpreter call altogether. (And the "force_all_plays_to_run" can be set to true to override this check if necessary.)

 - name: Check for existing Satellite certificate file
   stat: path=/etc/rhsm/ca/katello-server-ca.pem
   register: katello_pem

 - name: Execute the bootstrap.py script
   command: "/var/tmp/bootstrap.py ...."
   when: not katello_pem.stat.exists or force_all_plays_to_run|bool

I must admit I don't see the benefit here. Checking that pem is pretty much the first thing bootstrap does.
And unless you pass bootstrap_additional_args: --force to the playbook, you get exactly the behavior you want, no? The only thing you would save is the start up of the python interpreter itself. And that's pretty quick.

Was the PEM check always there? I though an early version I used re-ran it regardless. Adding in the check saves copying the script. Again, not a big deal in the grand scheme of things so in your environment it might make sense to copy and run regardless.

[evgeni]

The PEM check is there since #120, so no, not always :)

[dglinder]

Ok - I retract my comment/addition as it is not directly aligned with the usage of the bootstrap.py script within an Ansible playbook.

[sean797]

Can this example also delete bootstrap.py after?

[dglinder]

@sean797 - Sure, the example would just need a "file:" module call with "state: absent". Something like this (untested):

 - name: Execute the bootstrap.py script
   file:
     path: /var/tmp/bootstrap.py
     state: absent

this has so far only got positive feedback, and given it's not a code change, but an example, I am going to just merge that now :)
