Playbook that takes IP address of host machines and store these IPs

[PMP]

Hi,

Can anyone help me to get the playbook that collects the IP addresses of different host machines and store the output to a file.

Thanks,

[Stefan Hornburg (Racke)]

Which method do you want to use to collect the IP addresses? Maybe you can pick from one of these inventory plugins at
https://docs.ansible.com/ansible/latest/plugins/inventory.html#plugin-list?

Hi Stefan,

Thanks for the quick reply. Actually my requirement is to collect the all IP Addresses of different Host machines and store those IP's to a file in the controller.

Thanks,

The playbook and the template below stores first IP found of all hosts into
the file my_ips.txt in the current directory of the controller (localhost)

shell> cat pb.yml
- hosts: all
gather_facts: true
tasks:
- template:
src: my_ips.txt.j2
dest: my_ips.txt
run_once: true
delegate_to: localhost

shell> cat my_ips.txt.j2
{% for my_host in groups.all %}
{{ hostvars[my_host].ansible_all_ipv4_addresses.0 }}
{% endfor %}

For example, with the inventory

shell > cat hosts
test_01 ansible_host=10.1.0.51
test_02 ansible_host=10.1.0.52
test_03 ansible_host=10.1.0.53
test_06 ansible_host=10.1.0.56
test_09 ansible_host=10.1.0.59

the playbook gives

shell> cat my_ips.txt
10.1.0.51
10.1.0.52
10.1.0.53
10.1.0.56
10.1.0.59

Notes to experiment and customise the playbook:

* Change "hosts"
* Change the list of hosts "groups.all"
* Take all items of the list "ansible_all_ipv4_addresses"
* "gather_facts: true" (default) is needed to collect
"ansible_all_ipv4_addresses"
* "run_once: true" is needed to run the task only once
* "delegate_to: localhost" is needed to store the file at controller
