Please bear with me for a basic question but I'm very new to Ansible and trying to create my first playbook for Windows servers. I have a scenario where I need to set the value of a variable based on a condition, if the server name contains 'Z', use one value, else use a different value. Is this syntax correct? Thank you!

vars:
    my_variable: "{{ 'value_if_contains_Z' if 'Z' in inventory_hostname else 'default_value' }}"

• This question is similar to: How to pass different value in different condition of the same variable in Ansible? or Conditionally define variable in Ansible or How to use IF ELSE in YAML with variable?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. – U880D Commented Mar 15 at 0:00

For a not optimal structured inventory file example.ini (annot.: see also How to build your inventory)

[locations]
usazure.example
caazure.example
usgcp.example
cagcp.example
usaws.example
caaws.example

a minimal example playbook

---
- hosts: locations
  become: false
  gather_facts: false

  vars:

    platform: "{{ 'azure' if inventory_hostname_short is search('z') else 'other' }}"

  tasks:

    - debug:
        var: platform

will result into an output of

TASK [debug] ***************
ok: [usazure.example] =>
  platform: azure
ok: [caazure.example] =>
  platform: azure
ok: [usgcp.example] =>
  platform: other
ok: [cagcp.example] =>
  platform: other
ok: [usaws.example] =>
  platform: other
ok: [caaws.example] =>
  platform: other

An other syntax will produce the same results

    platform: "{{ 'azure' if 'z' in inventory_hostname_short else 'other' }}"
