Puppet to Ansible, how to example

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 %}
