Ansible check if inventory_hostname is in list

I am trying to check if inventory_hostname is in a list into an imported variable.



vars/users.yml file:
---
users:

- username: user1
comment: "User 1"
group: admin
password: "sha password"
keys:
active:
- "ssh-rsa etc"
admin: yes

- username: user2
comment: "User 2"
group: users
groups: deployer
keys:
active:
- "ssh-rsa etc"
hosts:
user:
- host1
- host2
deployer:
- host3


I want to execute a task only if inventory_hostname is into any of hosts lists (user, deployer, others ...).



I tried this:



- name: Create users
user:
name: "{{ item.username }}"
comment: "{{ item.comment | default('User {{item.username}}') }}"
password: "{{ item.password | default('!') }}"
state: "{{ item.state | default('present') }}"
shell: "{{ item.shell | default('/bin/bash') }}"
group: "{{ item.group | default('users') }}"
with_items: '{{ users }}'
when: item.username is defined and ((item.admin is defined and item.admin == True) or (item.hosts is defined and item.hosts.user is defined and inventory_hostname in item.hosts.user)


It works for user1 (which have admin enabled) but not for user2 (if this play is executed on host1 which is included into user2's hosts.user list).

          Well .. I tried your code snippet and it works well for both users. Only thing which can make it fail is that hostnames in item.host.user are not matching the inventory_hostname. You can try to debug the inventory_hostname before this task to see what are the inventory hostnames read by ansible and whether you have specified them correctly in item.host.user list.



          - debug: var=inventory_hostname

          • Thanks Kanwar! I am happy that my snippet was working, in effect I was missing the domain name into item.host.user! :-( One more question: how do you think it would be possible to check if inventory_hostname is into one of the subkeys of item.host (item.host.user or item.host.deployer) without checking one by one? Thanks!
