traversal through the loop in ansible playbook - loops

Question

I am newbie to ansible and trying to write my first playbook.
- name: create volume
volume:
state: present
username: "{{ username }}"
password: "{{ password }}"
hostname: "{{ inventory_hostname }}"
vserver: "{{item[0]}}"
name: "{{item[1]}}"
aggregate_name: "{{output}}"
with_nested:
- [ 'vs10' , 'vs11' ]
- [ 'vol1' , 'vol2', 'vol3' , 'vol4' ,'vol5', ''vol6']
connection: local
Actual output:
vs10-vol1 vol2 vol3 vol4
vs11- vol1 vol2 vol3 vol4
Expected output:
vs10-vol1, vol3 vol5
vs11-vol2, vol4 vol6

Answer 1

This would probably work. I'm basically looping the task against volumes and calculating the vserver in the task.
- name: create volume
volume:
state: present
username: "{{ username }}"
password: "{{ password }}"
hostname: "{{ inventory_hostname }}"
# Calculate which vserver to use based on 'current volume index in the volumes list' and 'length of vservers list'.
# The logic uses modulus to try and distribute volumes across given vcenters
vserver: "{{vservers[(current_index % (vservers|length))]}}"
# Name is item itself because you are looping volumes
name: "{{item}}"
aggregate_name: "{{output}}"
# Loop the volumes
loop: [ 'vol1' , 'vol2', 'vol3' , 'vol4' ,'vol5', 'vol6']
# This is make a loop_control variable available. This will give us 'current_index'
loop_control:
index_var: current_index
# Vservers are defined here
vars:
vservers: [ 'vs10' , 'vs11' ]
