variable undefined?

[Dave York]

I'm confused why I'm getting a 'variable undefined' error with this playbook, anyone have any idea?

- hosts: localhost

  connection: local

  gather_facts: yes

  tasks:

  - name: Generate a temporary random password for template/os customization

    set_fact: 

      randopass: "{{ lookup('password', '/dev/null length=24 chars=ascii_letters') }}"

  

... I use '{{ randopass }}' somewhere else in this play and its fine... but then I get to this part:

- hosts: staging

  vars:

      ansible_user: Administrator

      ansible_password: '{{ randopass }}'

  gather_facts: yes

ERROR:

The field 'password' has an invalid value, which includes an undefined variable. The error was: 'randopass' is undefined

Hi,

Variable are for a host.... You use "localhost" and "staging"

unless the group staging contains only localhost, yes you will have some undefined variable for the different hosts in your staging group

Instead of "hosts: localhost" run the play with "hosts: staging" and limit
the fork to "run_once: true". For example

- hosts: staging

tasks:
- name: Generate a temporary random password for template/os customization
set_fact:

randopass: ...
run_once: true

This way the variable "randopass" will be defined in the "hostvars" of all
hosts in the group staging.

HTH,
