varible hosts

Archives Ansible Project
1

[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
