Describe the solution you'd like
If we have config.yml like:
(please keep to around 10 lines )

hosts:
- {name: node1, address: 172.16.0.2, port: 22, user: ubuntu, password: "Ubuntu@123"}
- {name: node2, address: 172.16.0.3, port: 22, user: ubuntu, password: "Ubuntu@123"}
- {name: node3, address: 172.16.0.4, port: 22, user: ubuntu, password: "Ubuntu@123"}
- {name: node4, address: 172.16.0.5, port: 22, user: ubuntu, password: "Ubuntu@123"}
- {name: node5, address: 172.16.0.6, port: 22, user: ubuntu, password: "Ubuntu@123"}
- {name: node6, address: 172.16.0.7, port: 22, user: ubuntu, password: "Ubuntu@123"}
roleGroups:
  etcd:
  - node1
  - node2
  - node3
  ceph:
  - node1
  - node2
  - node3
  master:
  - node1
  - node2
  - node3
  worker:
  - node1
  - node2
  - node3

And we run a command:

masters_hostname=$(yq .roleGroups.master.[] config.yaml)

it could output

node1
node2
node3

Describe alternatives you've considered
