Functions ¶

func Add ¶

func Add(node, newNode *yaml.RNode) (err error)

Add adds the subset to the target at the path, appends to lists

func Delete ¶

func Delete(node *yaml.RNode, filters []yaml.Filter, pathParts []PathPart, operandIdx int) (err error)

Deletes data at the path

func SetNodeAtPath ¶

func SetNodeAtPath(rootNode *yaml.RNode, node *yaml.RNode, filters []yaml.Filter, pathParts []PathPart, finalItemIdx int) error

SetNodeAtPath injects the updated node into rootNode according to the specified path and final node type

func Update ¶

func Update(node, newNode *yaml.RNode) (*yaml.RNode, error)

Updates existing data at the path, overwrites lists

Types ¶

type ChangeType ¶

type ChangeType string

const (
	ChangeTypeAdd    ChangeType = "add"
	ChangeTypeUpdate ChangeType = "update"
	ChangeTypeDelete ChangeType = "delete"
)

type PartType ¶ added in v0.14.0

type PartType int

const (
	PartTypeMap      PartType = iota // e.g., a in a.b
	PartTypeSequence                 // e.g., a in a[b=c]
	PartTypeScalar                   // e.g., b in a.b
	PartTypeSelector                 // e.g., [a=b]
	PartTypeIndex                    // e.g., [0]
)

type PathPart ¶ added in v0.14.0

type PathPart struct {
	Type  PartType
	Value string
}

func PathToParts ¶ added in v0.14.0

func PathToParts(path string) []PathPart

PathToParts converts the path string into a slice of pathParts

func ResolvePathWithFilters ¶ added in v0.14.0

func ResolvePathWithFilters(targetNode *yaml.RNode, path string) ([]PathPart, []yaml.Filter, error)

ResolvePathWithFilters converts a path to its individual parts which define the type of part along with the appropriate kyaml filters to apply to the path

type TransformTarget ¶

type TransformTarget struct {
	RootNode *yaml.RNode
}

func CreateTransformTarget ¶

func CreateTransformTarget(parent map[string]interface{}) (*TransformTarget, error)

func (*TransformTarget) ExecuteTransform ¶

func (t *TransformTarget) ExecuteTransform(path string, cType ChangeType, value string, valueMap map[string]interface{}) (map[string]interface{}, error)

func (*TransformTarget) UpdateRootNode ¶ added in v0.14.0

func (t *TransformTarget) UpdateRootNode(node *yaml.RNode) (map[string]interface{}, error)

UpdateRootNode updates the root node of the transform target and returns the updated node as a map[string]interface{}
