I use ansible a lot for work and for my home lab. I love it.I keep needing an approach that so far has stumped me, so asking here for advice. I want to create a single file (an icinga2_hosts.conf) which has a separate collection of attributes from each host in my hosts inventory file. I would like to use jinja2 to template one instance and iterate through the hosts building the file in one go; not host by host in the usual ansible approach... although if a single file can be built by that method, I'm all ears.
You can iterate through your hosts with
{% for host in ansible_play_hosts %}
...
{% endfor %}
and use hostvars[host]['myattribute'] to access an attribute from you inventory.
To create the file, use template or copy with content parameter and add
run_once: yes
delegate_to: localhost

I think I could duplicate the hosts section in the vars section and then iterate the yaml data for the single file with a loop. I could actually create a file for each host and that would actually work in icinga2. But I want it in a single file for future readability and to avoid having to look in each host file for some anomaly. I could give up on ansible for this and use python and jinja2 to pass the hosts inventory file to a jinja2 render function. Is there a way to actually read the hosts inventory in traditional ansible style and iterate it into a single file using jinja2 as the template mechanism? I've wanted to do this in other scenarios but abandoned those attempts. Any tips and tricks appreciated.
