varible hosts

[rupesh alasundkar]

[1] peer{{ peer_number }}.peers   and   [2]peer{{ peer_number }}.peers.cluster{{ cluster }} are my 2 hosts.

NOTE:   {{ peer_number }}   and   {{ cluster }} is there any way i can use these both and can use in hosts: position????

my condition is

if i am passing ansible-playbook text.yml -e cluster=1 peer-number=1  [2] host will be in use. ((  peer1.peers.cluster1  ))

if i am passing ansible-playbook text.yml -e cluster=0 peer-number=1  [1] host will be in use  (( peer1.peers ))

bottom line is i want to use 2 varibles in hosts:

and want to pass  only 2 argument i.e.   {{ peer_number }} & {{ cluster }}

thanks
