Ansible Facts contain useful information during playbooks executions in order to take some decision or use them based on this information. On the other hand, it is a powerful tool to collect some extra information about the nodes which are beeing managed by Ansible.
In order to understand this lesson properly, a set of steps have been designed to be implemented in the following section.
ENJOY !!!
- Create an inventory file named "inventory" with a group named "myinstance" and your internal instance IP assigned included
- Create a playbook named "facts-playbook.yml" using "myinstance" as a hosts parameter and
<studentxx>as a user. The playbook should use tasks to ensure that the following conditions are met on the managed hosts:- Create a folder /named "etc/ansible/facts.d"
- Create a custom facts "/etc/ansible/facts.d/custom.fact" file with a variable named "haproxy_ip" which includes instance ip
- Print local facts "haproxy_ip"
- Create a new variable named "life_variable" with date content
- Print variable "life_variable"
- Before running your playbook, run the ansible-playbook --syntax-check command to verify that its syntax is correct
- Run the playbook!
