Hi
This is slightly more involved, you can use the json_query filter, it has a
little bit different syntax.
If you are going to iterate over a number of those subnets, I suggest
creating a dedicated variable for that.
Something like this:
tasks:
- set_fact:
subnets: "{{ subnet_output |
json_query('current[0].fvTenant.children[0].fvBD.children[].fvSubnet.attributes.ip')
}}"
- debug: var=subnets
- debug:
msg: "{% for subnet in subnets %}Subnet: {{ subnet }}\n{% endfor %}"
