yamlutils: Go package for working with yaml

Introduction

Imagine you have parsed a yaml like this with sigs.k8s.io/yaml/goyaml.v3:

apiVersion: example.com/v1
kind: Foo
metadata:
  labels:
    foo: bar
spec:
  level1:
    level2:
      level3:
        field: myValue

You can easily get the value of the deeply nested field like this:

s, found, err := NestedString(node, "spec", "level1", "level2", "level3", "field")

In above example s contains "myValue", found is true, and err is nil.

If you try to access a field which does not exit, found will be false.

If the value you try to get exists, but the data types does not match, err will be non-nil.
