Functions

func GetAmazonCloudWatchAgentResource

func GetAmazonCloudWatchAgentResource(ctx context.Context, c client.Client, name string) v1alpha1.AmazonCloudWatchAgent

func InjectAnnotationKey

func InjectAnnotationKey(instType Type) string

InjectAnnotationKey maps the instrumentation type to the inject annotation.

Types

type AnnotationMutation

type AnnotationMutation interface {
	// Mutate attempts to modify the annotations map. Returns the mutated annotations if any.
	Mutate(annotations map[string]string) map[string]string
}

AnnotationMutation is used to modify an annotation map.

func NewInsertAnnotationMutation

func NewInsertAnnotationMutation(annotations map[string]string) AnnotationMutation

NewInsertAnnotationMutation creates a new mutation that inserts annotations. Any missing annotation key is sufficient for it to attempt to insert.

func NewRemoveAnnotationMutation

func NewRemoveAnnotationMutation(annotations []string) AnnotationMutation

NewRemoveAnnotationMutation creates a new mutation that removes annotations. All provided annotation keys must be present for it to attempt to remove them.

type AnnotationMutator

type AnnotationMutator struct {
	// contains filtered or unexported fields
}

func NewAnnotationMutator

func NewAnnotationMutator(mutations []AnnotationMutation) AnnotationMutator

NewAnnotationMutator creates a mutator with the provided mutations that can mutate an Object's annotations.

func (*AnnotationMutator) Mutate

func (m *AnnotationMutator) Mutate(obj metav1.Object) map[string]string

Mutate modifies the object's annotations based on the mutator's mutations. Returns all the mutated annotations.

type Type

type Type string

Type is an enum for instrumentation types.

const (
	TypeJava   Type = "java"
	TypeNodeJS Type = "nodejs"
	TypePython Type = "python"
	TypeDotNet Type = "dotnet"
	TypeGo     Type = "go"
)

type TypeSet

type TypeSet map[Type]any

TypeSet is a map with Type keys.

func NewTypeSet

func NewTypeSet(types ...Type) TypeSet

NewTypeSet creates a new set of Type.
