如何在使用 yq 命令解析 yaml 文件时在结果中包含密钥

how to include key in the result while parsing yaml file with yq command

如何获取包含键的值?这里是输入:

istio_cni:
  enabled: false
  repair:
    enabled: true

istiocoredns:
  enabled: false

global:
  hub: docker.io/istio
  tag: 1.4.5
  logging:
    level: "default:info"

预期输出是整个 global 块:

global:
  hub: docker.io/istio
  tag: 1.4.5
  logging:
    level: "default:info"

yq 给出的结果不包括 global 键:

$ yq r /tmp/values.yaml global
hub: docker.io/istio
tag: 1.4.5
logging:
  level: "default:info"

得到yq作者的回答

$ yq r /tmp/values.yaml global -p pv
global:
  hub: docker.io/istio
  tag: 1.4.5
  logging:
    level: "default:info"
-p is for print mode

pv is one of a print mode - (v (values, default), p (paths), pv (path and value pairs) (default "v")
