Variables

Breaking Up Variable files​

  1. After creating new role, delete /vars/main.yml and /defaults/main.yml
  2. Create main folder in each, e.g. /vars/main/ and /defaults/main
  3. Each file put into that new main folder will be imported, e.g. /vars/main/myfile1.yml , /vars/main/myfile2.yml

Precedence​

a

Checking if result is in list​

my_list: ['cats', 'dogs'] {{ 'cats' in my_list }}

Use template to simplify variable assignment​

- name: Set fact based on more complicated template data
  ansible.builtin.set_fact:
    my_complex_fact: "{{ lookup('ansible.builtin.template', 'my_template.j2') }}
  var:
    my_template_var: "value of foo"

lookup('ansible.builtin.template', 'my_formating_template.j2')

Adding result to already created JSON​

my_collection_variable | community.general.lists_mergeby(my_new_data, 'my_merge_key', list_merge='append')

Use variable at play level​


- name: My example task within a play
  ansible.builtin.template:
    src: my_sweet.template.yml.j2
    dest: /etc/my_app/config_file
  vars:
    my_first_var: "foo"
    my_second_var: "{{ bar }}"
