如何更新sample.yaml里的内容

sample.yaml
` hosts:
##You should complete the ssh information of the hosts

{name: v3-prod1, address: 192.168.1.251, internalAddress: 192.168.1.251}
{name:v3-test1 address: 192.168.1.247, internalAddress: 192.168.1.247,user: root, privateKeyPath: “/vsais-v3.pem”}
{name: k8s-worker-02, address: 192.168.1.187, internalAddress: 192.168.1.187,user: root, privateKeyPath: “/vsais-v3.pem”}
{name: k8s-worker-03, address: 192.168.1.198, internalAddress: 192.168.1.198,user: root, privateKeyPath: “/vsais-v3.pem”}
roleGroups:
etcd:
- v3-prod1
  master:
- v3-prod1
  worker:
- v3-prod1
- v3-test1
- k8s-worker-02
- k8s-worker-03
  `

1、我想把v3-prod1的worker角色去除掉，只作为master
2、我想把v3-test1的名称换为k8s-worker-01
配置文件修改后，如何更新整个集群？
