More accurately, the data structure you posted isn't a variable, it's an
item from a "upper" list variable - which we don't know the name of.
An example:
---
- hosts: localhost
connection: local
gather_facts: no
vars:
domain_definition:
- name: server11
cluster: cluster1
port: '8080'
- name: server12
cluster: cluster2
port: '8090'
- name: server21
cluster: cluster3
port: '9080'
- name: server22
cluster: cluster4
port: '9090'
tasks:
- name: Keep names
debug:
msg: "{{ domain_definition | json_query('[*].{name: name}') }}"
Gives:
TASK [Keep names]
**************************************************************
ok: [localhost] =>
msg:
- name: server11
- name: server12
- name: server21
- name: server22
