Puppet to Ansible, how to example - puppet

Question

I'm in the process of setting up Ansible to take over for a puppet install.
I see puppet manifest that is setting up a ypbind file, and it pushes out a slightly different version of the yp.conf file based on hostname.
So I have the following puppet definitions:
class ypbind {
file {'yp.conf':
ensure => file,
content => template("ypbind/yp.conf.erb"),
owner => 'root',
group => 'root',
mode => '0644',
notify => Service['ypbind'],
path => '/etc/yp.conf',
}
service {'ypbind':
enable => true,
ensure => running,
}
}
Followed by this template (domains and IPs sanitized)
<% case
when #hostname =~/(^[p|d]NY-)/ -%>
#New York Data Center NIS
domain NY1.domain.com IP1
domain NY2.domain.com IP2
domain SF1.domain.com IP3
<%when #hostname =~/(^[p|d]SF-)/ -%>
#San Fran Data Center NIS
domain SF1.domain.com IP1
domain SF2.domain.com IP2
domain NY1.domain.com IP3
<% else -%>
#Default to NY DC
domain NY1.domain.com IP1
domain NY2.domain.com IP2
<% end -%>
My question is how do I replicate this logic using Ansible?
I think I figured out a way to do it with hostname, but I'd have to use multiple files. Is there a way to do the same thing in ansible as this puppet example?

- hosts: all
sudo: yes
gather_facts: yes
user: ansible
tasks:
- name: update NY ypbind
template: src=/etc/ansible/files/yp.conf.NY dest=/etc/yp.conf mode=0644 owner=root group=root
notify: restart ypbind
when: ansible_hostname | match('^[p|d]NY-test01')
- name: update SF ypbind
template: src=/etc/ansible/files/yp.conf.SF dest=/etc/yp.conf mode=0644 owner=root group=root
notify: restart ypbind
when: ansible_hostname | match('^[p|d]SF-test01')
handlers:
- name: restart ypbind
- service: name=ypbind state=restarted
I think after research, I'd just use the jinja2 template system, just not sure how quite yet...

For anyone else that might be interested, it turned out to be pretty simple. It was just the following.
ypbind.yaml

- hosts: all
sudo: yes
gather_facts: yes
user: ansible
tasks:
- name: update NY ypbind
template: src=/etc/ansible/files/yp.conf.j2 dest=/etc/yp.conf mode=0644 owner=root group=root
notify: restart ypbind
handlers:
- name: restart ypbind
service: name=ypbind state=restarted
yp.conf.j2
{% if ansible_hostname |match ('^[p|d]sf-') %}
domain SF.domain.com server 10.200.0.1
domain SF.domain.com server 10.200.0.2
domain NY.domain.com server 10.201.0.1
{% else %}
domain NY.domain.com server 10.201.0.1
domain NY.domain.com server 10.201.0.2
domain SF.domain.com server 10.200.0.1
{% endif %}
