Iterate sub-items Ansible with sublements - ansible

Question

Have task which copies each user's key
- name: SSH Keys
authorized_key:
user: "{{ item.0.name }}"
key: "{{ item.0.ssh_key.0.key }}"
state: "{{ item.0.ssh_key.0.state }}"
when:
- item.1 == 'all' or item.1 in group_names or item.1 == inventory_hostname
with_subelements:
- "{{ users }}"
- servers
Var list:
users:
- name: user1
ssh_key:
- key:
- "key1.user1"
- "key2.user1"
- "key3.user1"
state: present
servers:
- server1
- name: user2
ssh_key:
- key:
- "key1.user2"
- "key2.user2"
state: present
servers:
- all
QUESTION: How can we allow users to copy multiple keys? Without deleting servers from with_subelements.
When starting the task, either the last key or an array with keys is copied, depending on how we write it in var list.
In this format copied last key.
- key: "key1.user1"
- key: "key2.user1"
- key: "key3.user1"
In this array.
- key:
- "key1"
- "key2"

Answer 1

Let's fit the structure of the data to this purpose. For example,
users:
- name: user1
ssh_key:
- "key1.user1"
- "key2.user1"
- "key3.user1"
state: present
servers:
- server1
...
It's possible to loop include_tasks. For example, create the task (test it with debug first)
shell> cat conf_authorized_key.yml
- name: SSH Keys
# authorized_key:
debug:
msg:
- "user: {{ item.0.name }}"
- "state: {{ item.0.state }}"
- "key: {{ iitem }}"
loop: "{{ item.0.ssh_key }}"
loop_control:
loop_var: iitem
Then include it in the playbook
shell> cat playbook.yml
- hosts: localhost
vars:
users:
- name: user1
ssh_key:
- "key1.user1"
- "key2.user1"
- "key3.user1"
state: present
servers:
- server1
- name: user2
ssh_key:
- "key1.user2"
- "key2.user2"
state: present
servers:
- all
tasks:
- name: Loop include_task
include_tasks: conf_authorized_key.yml
loop: "{{ users|subelements('servers') }}"
loop_control:
label: "{{ item.1 }}"
when: (item.1 == 'all') or
(item.1 in group_names) or
(item.1 == inventory_hostname)
gives
shell> ansible-playbook playbook.yml
