How to access an host variable defined in inventory

[Valentino Gagliardi]

Hello friends
maybe a noob question but I'm unable to get host variable work as expected. This is my question.

Given this template:

object Host "{{ hostvars[item]['ansible_fqdn'] }}" {
  import "generic-host"
  address = "{{ hostvars[item]['ansible_eth0']['ipv4']['address'] }}"
  vars.os = "Linux"
  vars.sla = "24x7"
  vars.http = "yes"
  vars.smtp = "yes"
}

generated by this task:

- name: Copy Host Definitions
  template: src=host_def.j2
            dest={{ icinga2_hosts_dir }}{{ hostvars[item]['ansible_fqdn'] }}.conf
            owner=root
            group=root
            mode=0644
  with_items: groups['monitored']
  notify:
   - restart icinga2

How I can access an host variable eventually defined in inventory?

[monitored:children]
myservers

[myserver]
host1 vars_http=no

What I want to do is something like this:

object Host "{{ hostvars[item]['ansible_fqdn'] }}" {
  import "generic-host"
  address = "{{ hostvars[item]['ansible_eth0']['ipv4']['address'] }}"
  vars.os = "Linux"
  vars.sla = "24x7"
{% if vars_http == "no" %}
  vars.http = "no"
{% else %}
  vars.http = "yes"
{% endif %}
  vars.smtp = "yes"
}

Thanks for support.

Since you appear to be walking over "hostvars" are you trying to have a template that includes the variables for every host in a certain group?

If so, we know how to do that.

Let us know.
