How do you list all Ansible facts?
To see all available facts, add this task to a play:
- – name: Print all available facts ansible.builtin.debug: var: ansible_facts.
- {{ ansible_facts[‘devices’][‘xvda’][‘model’] }}
- {{ ansible_facts[‘nodename’] }}
What is Hostvars?
hostvars is a hash with inventory hostnames as keys. To access fields of each host, use hostvars[‘test-1’] , hostvars[‘test2-1’] , etc. ansible_ssh_host is deprecated in favor of ansible_host since 2.0.
How do you stop Ansible gathering facts?
You can use gather_facts: no keyword in your playbook. It will disable this task automatically.

Didn’t read carefully enough. This (AFAIK) isn’t possible. The primary limitation that stops us doing this (no matter how you spin it), is ‘variable expansion’ in ansible is a single pass process and what you want requires multiple-passes. Create the playbook dynamically from your playbook using template and execute it.
What can I use as an alternative to Ansible _ hostname?
You can use the magic variable inventory_hostname, the name of the host as configured in your inventory, as an alternative to ansible_hostname when fact-gathering is disabled. If you have a long FQDN, you can use inventory_hostname_short, which contains the part up to the first period, without the rest of the domain.
Where to find custom facts in Ansible playbook?
The ansible_local namespace separates custom facts created by facts.d from system facts or variables defined elsewhere in the playbook, so variables will not override each other. You can access this custom fact in a template or playbook as:
How to disable the fact gathering in Ansible?
To disable fact gathering: The setup module in Ansible automatically discovers a standard set of facts about each host. If you want to add custom values to your facts, you can write a custom facts module, set temporary facts with a ansible.builtin.set_fact task, or provide permanent custom facts using the facts.d directory.
