Hello Group,
I'm looking for a way to access facts for my hostnames through the hostvars
and groups methods. This all works well, but I'm stuck when I try to limit
the batch size with the "serial" directive.
For example: I have 10 web servers that I want to do rolling update using
the "serial: 50%".
{% for host in groups['app_servers'] %}
{{ hostvars[host]['ansible_eth0']['ipv4']['address'] }}
{% endfor %}
Using the above example will give me all hosts in the group "app_servers"
and there is no way to get only 50% of the hosts.
Is there a way to get facts information for "all hosts in the scope" and
"all hosts outside of scope"?
