I'm stuck. I'm sure this can all be done a better way, but right now, I'm just
not seeing it. Can anyone offer suggestions of what else to try here?
Originally I started with one operating system, so it writing up a ansible
playbook for the core OS configuration was simple and I ended up with a lot of
stanzas like this:
- hosts: all:!tftp-server
sudo: true
tasks:
- name: Ensure tftpd server removed
yum: name=tftp-server state=absent
- hosts: tftp-servers
sudo: true
roles:
- tftp-server
And I did this for *EVERY SERVICE* (xinetd, vsftpd, httpd, etc....) on my
hosts. In short, if it didn't have to be on, it had to be explicitly disabled.
[If there's a better form for these types of patterns, PLEASE let me know -
it's so verbose and ugly, especially duplicated for every service I have on my
boxes.]
Now, I'm adding a second OS to my playbooks. So I created a second parallel
playbook with similar code customized for the new OS. But now, my problem is
that when I'm setting up a new box, how do I have Ansible determine which
playbook to run? My head is telling me what I want to do is this: create an
Ansible playbook 'os_core.yml' which can determine the distro/version of the OS
on the target box then execute the correct OS-specific playbook for that
distro/version. But how do I do that? I can't do include playbook with
variables in the path and I can't move all this to roles as I need to be able
to differentiate plays based upon host groups. I REALLY do not want to create
a giant single playbook which has rules for host groups based upon things like
'rhel5-tftp-server' vs 'centos6-tftp-server'. That just doesn't scale.
I'm open to any and all suggestions here.
Thx
Chris.
