Ansible: Iteration fails while looping over output variable

Question

Here is my debug output from an ansible playbook:

 "msg": { "changed": false, "failed": false, "instances": [ { ......... "private_dns_name": "ip-10-XXX-XXX-XX.ec2.internal", "private_ip_address": "10.XXX.XXX.XX", "product_codes": [], "public_dns_name": "", "root_device_name": "/dev/sda1", "root_device_type": "ebs", "security_groups": ["...."], "source_dest_check": true, ...... "private_dns_name": "ip-10.XXX.XXX.XX.ec2.internal", "private_ip_address": "10.XXX.XXX.XX", "product_codes": [], "public_dns_name": "", "root_device_name": "/dev/sda1", "root_device_type": "ebs", "security_groups": ["...."], "source_dest_check": true, } ] } } 

I want to do partition of disks from the created EC2 instances. output variable consists of IP addresses in JSON format where I want to loop through each IP address and get the disk information of the server, then I do partition using parted module as per below.

- name: Collect Disk Information setup: gather_subset: - hardware delegate_to: "{{ output.instances[0].private_ip_address }}" - name: Print disks Details debug: var: hostvars[inventory_hostname].ansible_devices.keys()|list - name: Create Partition parted: device: "/dev/{{ item }}" number: 1 part_type: 'primary' state: present delegate_to: "{{ output.instances[0].private_ip_address }}" with_items: "{{ hostvars[inventory_hostname].ansible_devices.keys() }}" 

This task can only do partition on the instances[0] array, I want to loop through all the private_ip_address in the output variable. How to achieve this?

I tried with below as well

Try 1:

 delegate_to: "{{ item.private_ip_address }}" loop: "{{ output.instances }}" 

Answer 1

For example

- hosts: localhost vars: output: instances: [ {"name": "ip-10", "ip": "10.1.0.10"}, {"name": "ip-20", "ip": "10.1.0.20"}] tasks: - debug: msg: "delegate_to: {{ item.ip }}" loop: "{{ output.instances }}" 

gives

 msg: 'delegate_to: 10.1.0.10' msg: 'delegate_to: 10.1.0.20'
