YAML toolkit

Go library to deal with YAML documents embedded within k8s manifests (like Spring boot's application.yaml).

Usage

Opening embedded YAML

example.yaml

---
kind: ConfigMap
metadata:
  name: cm1
  namespace: default
apiVersion: v1
data:
  application.yaml: |
    xyz: 456
    abc:
      def:
        leaf1: 123
        leaf2: Hello

code

package main

import (
    ydom "github.com/rkosegi/yaml-toolkit/dom"
    yk8s "github.com/rkosegi/yaml-toolkit/k8s"
)

func main() {
	d, err := yk8s.YamlDoc("example.yaml", "application.yaml")
	if err != nil {
		panic(err)
	}
	print (d.Document().Child("xyz").(ydom.Leaf).Value()) // 456
	d.Document().AddValue("another-key", ydom.LeafNode("789")) // add new child node
	err = d.Save()
	if err != nil {
		panic(err)
	}
}
