Creating users & groups with vars - not working

[Anfield]

Trying to create users and groups with vars inline...this is not working..what am I missing here?

--- # Users and Groups
- hosts: localhost
  become: yes
  vars:
     groups:
        - devops
        - dbadbmins
        - serveradmins

     users:
        - frank
        - joe
        - dave
  tasks:
    - name: Create groups
      group:
        name: "{{ item.groups }}"
        state: present
      with_items: "{{groups}}"
      ignore_errors: yes

    - name: Create users
      user:
        name: "{{ item.user }}"
        state: present
      with_items: "{{users}}"

Output -

You are trying to access item.groups, but there is not item.groups. The groupname is item itself. The same thing for item.user!

Just change item.groups to item and item.user to item

[Brian Coca]

To put Daniel's response into clear example:

- name: Create groups
group:
name: "{{ item }}"

state: present
with_items: "{{groups}}"
ignore_errors: yes

- name: Create users
user:
name: "{{ item }}"

state: present
with_items: "{{users}}"

Thanks Brian!

[Anfield]

Thanks. It works but only if I swap   with_items: "{{groups}}"   for with_items: "{{grouplist}}" 

and call my vars grouplist also. Something it didnt like about calling those 2 groups

[Brian Coca]

i should have noticed, 'groups' is a reserved var, which has a
dictionary with the inventory groups and the hosts that belong to
them.

No matter what you set, the 'groups' from Ansible will overwrite it.
