Hi everyone
I'm trying to use the item value in 'with_sequence' to access an element in
my array variable.
I understand that to access variables using the bracket syntax [...] in
- vars => use vars[...]
- hostvars => use hostvars[...]
But how to access an item in with_sequence using the bracket syntax [...]?
---
- name: Stage devices
hosts: localhost
gather_facts: false
connection: local
vars:
##Path to scripts
script_path: ~/ansible/playbooks
##Path to generated config files
config_path: ~/ansible/playbooks/configs
##Prefix for the Management
mgmt_prefix_ip: 172.30.100
##First IP address
mgmt_start_ip: 20
username: admin
password: password
device:
- { hostname: host1 }
- { hostname: host2 }
tasks:
- name: Paste configuration template
vars:
command: "{{ script_path }}/send-commands.exp {{ mgmt_prefix_ip }}.{{
item | int + vars['mgmt_start_ip'] }} {{ username }} {{ password }} {{
config_path }}/{{ vars['device'][item???]['hostname'] }}.txt"
with_sequence: start=0 end=1 format=%02x
register: command_result
- debug: var=command_result
Expected behaviour is
"item": "00" => {{ vars['device'][00]['hostname'] }} => host1 =>
command: ~/ansible/playbooks/send-commands.exp 172.30.100.20 admin
password ~/ansible/playbooks/configs}/host1.txt"
"item": "01" => {{ vars['device'][01]['hostname'] }} => host2 =>
command: ~/ansible/playbooks/send-commands.exp 172.30.100.21 admin
password ~/ansible/playbooks/configs}/host2.txt"
I've set the index value manually (e.g. vars['device'][00]['hostname']) and
it works but I want the index to be dynamic.
I've looked at the documentation but couldn't find the magic variable name.
https://docs.ansible.com/ansible/faq.html#how-do-i-access-a-variable-name-programmatically

Can you please help? I'm still a newbie.
Thanks.
