ansible / ansible.builtin / v2.6.2 / module / set_fact Set host facts from a task | "added in version" 1.2 of ansible.builtin" Authors: Dag Wieers (@dagwieers) stableinterface | supported by coreansible.builtin.set_fact (v2.6.2) — module
pip
Install with pip install ansible==2.6.2
This module allows setting new variables. Variables are set on a host-by-host basis just like facts discovered by the setup module.
These variables will be available to subsequent plays during an ansible-playbook run, but will not be saved across executions even if you use a fact cache.
Per the standard Ansible variable precedence rules, many other types of variables have a higher priority, so this value may be overridden. See L(Variable Precedence Guide,../user_guide/playbooks_variables.html#variable-precedence-where-should-i-put-a-variable) for more information.
This module is also supported for Windows targets.
# Example setting host facts using key=value pairs, note that this always creates strings or booleans - set_fact: one_fact="something" other_fact="{{ local_var }}"
# Example setting host facts using complex arguments - set_fact: one_fact: something other_fact: "{{ local_var * 2 }}" another_fact: "{{ some_registered_var.results | map(attribute='ansible_facts.some_fact') | list }}"
# Example setting facts so that they will be persisted in the fact cache - set_fact: one_fact: something other_fact: "{{ local_var * 2 }}" cacheable: true
# As of 1.8, Ansible will convert boolean strings ('true', 'false', 'yes', 'no') # to proper boolean values when using the key=value syntax, however it is still # recommended that booleans be set using the complex argument style: - set_fact: one_fact: true other_fact: false
cacheable: default: 'no' description: - This boolean indicates if the facts set will also be added to the fact cache, if fact caching is enabled. type: bool version_added: '2.4' version_added_collection: ansible.builtin key_value: description: - The C(set_fact) module takes key=value pairs as variables to set in the playbook scope. Or alternatively, accepts complex arguments using the C(args:) statement. required: true
