parse config.yaml with nodename

[willzhang]

config.yaml

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

Clusterfile.yaml, this not work,
I would like to know if it is possible to achieve this complex rendering through the go template. Can someone help me ?

apiVersion: apps.sealos.io/v1beta1
kind: Cluster
metadata:
  name: default
spec:
  hosts:
  - ips:
    {{range .Values.hosts}}
    {{if eq .name .roleGroups.master}}
    - {{.address}}
    {{end}}
    {{end}}
    roles:
    - master
    - amd64
  image:
  - registry.cn-hongkong.aliyuncs.com/labring/kubernetes:v1.25.6

run command

sealos apply -f Clusterfile.yaml --values config.yaml  --debug

and what i hope the final Clusterfile will be this:

apiVersion: apps.sealos.io/v1beta1
kind: Cluster
metadata:
  name: default
spec:
  hosts:
  - ips:
    - 172.16.0.2
    - 172.16.0.3
    - 172.16.0.4
    roles:
    - master
    - amd64
  image:
  - registry.cn-hongkong.aliyuncs.com/labring/kubernetes:v1.25.6

{{if has .name .roleGroups.master}}

yes ,this $.Values.roleGroups.master is better

  hosts:
  - ips:
    {{- range .Values.hosts }}
    {{ if has .name $.Values.roleGroups.master }}

获取roleGroups.master所有值

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

获取name对应的单个IP

yq '.hosts | map(select(.name == "node1"))' config.yaml | yq .[].address

获取指定范围name对应的所有IP

yq eval '.roleGroups.master[] as $server | .hosts[] | select(.name == $server)| .address' config.yaml
