Please refer to the attached file for issues I am running into...
*Here is my playbook:*
--- # Ansible facts example
- hosts: centos
tasks:
- name: create a file to write the fact values
lineinfile:
path: /home/ansible/hostname
create: yes
line: "{{ ansible_hostname }}"
- name: access magic variables
lineinfile:
path: /home/ansible/hostname
line: "{{ hostvars['centos']['ansible_default_ipv4']['address']
}}"
*And here is the command I am using to run it:*
ansible-playbook -i inv facts.yml
*And here is the inventory (host):*
[centos]
cen ansible_host=172.31.4.215
*I keep running into this error:*
PLAY [centos]

to retry, use: --limit @/home/ansible/facts.retry
PLAY RECAP

*How to resolve this?*
