The following task will find that:
- debug:
msg: "{{ hostinfo|dictsort|selectattr('1.hostclass', 'equalto',
'ess')|first|first }}"
That takes the `hostinfo` dict, turns it into a list of tuples, selects
where `hostclass` equals `ess`, gets the first result (there should only be
one here), and then gets the first element.
If you don't have jinja2 version with the `equalto` test, you can replace
that with `search` or `match`
It outputs:
TASK [debug]
*
ok: [localhost] => {
"msg": "host002"
}
