Conditionally define variable in Ansible

Question

I want to conditionally define a variable in an Ansible playbook like this:

my_var: \"{{ \'foo\' if my_condition}}\"
         


        

Answer 1

I believe you're after the default(omit) filter. (Reference).

As per the example, mode will behave like it wasn't set at all for the first two items in the loop.

- name: touch files with an optional mode
  file:
    dest: "{{item.path}}"
    state: touch
    mode: "{{item.mode|default(omit)}}"
  loop:
    - path: /tmp/foo
    - path: /tmp/bar
    - path: /tmp/baz
      mode: "0444"
