I am new to ansible.
Why is my playbook not working?
You have a couple of things you need to change.
---
- name: print out ip adressess
hosts: db_servers
gather_facts: True
vars:
- nic: "enp0s8"
- full_line: ""
vars is a dict not a list so you need to remove those dashes in front.
tasks:
- debug: var=ansible_{{ nic }}.ipv4.address
- set_fact: full_line="{{ full_line }} {{
hostvars[item].ansible_enp0s8.ipv4.address }}"
loop: "{{ groups['db_servers'] }}"
- debug:
msg: "{{ full_line }}"
- set_fact: full_line="{{ full_line }} {{ hostvars[item].ansible_{{ nic
}}.ipv4.address }}"
loop: "{{ groups['db_servers'] }}"
You can't use {{ }} inside {{ }}, so you need to concatenate stings to make it
work.
{{ hostvars[item]['ansible_' ~ nic].ipv4.address }}
You could drop the loop by using this
- set_fact:
full_line: "{{ groups['db_servers'] | map('extract', hostvars, ['ansible_' ~
nic, 'ipv4', 'address']) | join(' ') }}"
