How to access an host variable defined in inventory

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.
