Ansible looping over sub-lists

I have a yaml for the creation of a user.

 users:  
   username:  
    uid: 12345  
    gid: 6789  
    secggroups:  
         - group1  
         - group3  
    gecos: user_for_xyz  
    home: /home/username

I also have a file with just the usernames called users_list. The playbook to create users is as follows:

---  
\- name: create users
  user: name="{{ item }}" uid={{ users[item]['uid'] }} group={{ users[item][gid] }} comment="{{ users[item]['gecos'] }}" home={{ users[item]['home' }} expires=0  
  with_items:  
    \- users_list

How can I loop through the groups to be added to user?

You can solve this using subelements like this:


- name: User creation
   user:
    name:"{{item.0.username}}"
    groups: "{{item.1 }}"
  with_subelements:
    - "{{ users }}"
    - groups

here is a sample to debug, like a directory tree:


vars:
  test:
    - name: Testing subelements loop
      dir: dir0

      subdir:
        - subdir0
        - subdir1
        - subdir2
tasks:
  - name: Subelements loop sample
    debug:
      msg: "{{ item.0.dir }}/{{ item.1 }}"
    with_subelements:
      - "{{ test }}"
      - subdir

Your playbook is on the right track.

Try this for the users variable:

 users:  
   - username: someusername  
     uid: 12345   
     gid: 6789  
     groups:  
         - group1  
         - group3  
     gecos: "Some user"  
     home: /home/someusername  
   - username: someusername  
     ... etc ...

And this for the user play

- name: User creation
  user: 
    name:"{{item.username}}"
    groups: "{{item.groups | join(',')}}"
    comment: "{{item.name}}"
    uid: "{{item.uid}}"
  with_items: users

Note that I modified your syntax to not use inline YAML.

Also you may find this users role helpful.
