Ansible set_fact value of No converted into False

I'm having an annoying issue with set_fact, I set a var with value No but once I use the var in a template Ansible converts it to False. Is there a way around this YAML Norway problem? A single-quoted 'No' is converted to an unquoted False in the file.

Solution

  • We can use multi line scalar YAML syntax to get around this and have the text No in the file contents.

    Consider a simple text file sample.txt as below:

    works? Yes

    I am using an example with lineinfile (Linux), but should work similarly for Windows. A simple playbook with below tasks:

    - set_fact:
    var1: >
      No
- lineinfile:
    path: /tmp/sample.txt
    line: "works? {{ var1 }}"
    regexp: "^works"

    When this playbook is run:

    -works? Yes
+works? No
