Just off the top of my head you can use set_fact.
- name: Set datacenter variable based on hostname
set_fact:
datacenter: "datacenter{{ ansible_hostname[-1] }}"
when: ansible_hostname | regex_search('^[a-zA-Z0-9]*[1-2]')
You can then just use {{ datacenter }} and it should populate correctly. I
haven't tested the above, but if it doesn't work it should at least put you
in the ball park.
