Functions

func CalculateWorkloadRuntimeObjectName

func CalculateWorkloadRuntimeObjectName[T string | WorkloadKind | WorkloadKindLowerCase](workloadName string, workloadKind T) string

func ClientObjectFromWorkloadKind

func ClientObjectFromWorkloadKind(kind WorkloadKind) client.Object

ClientObjectFromWorkloadKind returns a new instance of the client object for the given workload kind the returned instance is empty and should be used to fetch the actual object from the k8s api server

func GetInstrumentationLabelTexts

func GetInstrumentationLabelTexts(workloadLabels map[string]string, workloadKind string, nsLabels map[string]string) (workloadText, nsText, decisionText string, sourceInstrumented bool)

func GetInstrumentationLabelValue

func GetInstrumentationLabelValue(labels map[string]string) *bool

func IgnoreErrorKindNotSupported

func IgnoreErrorKindNotSupported(err error) error

Types

type DaemonSetWorkload

type DaemonSetWorkload struct {
	*v1.DaemonSet
}

func (*DaemonSetWorkload) AvailableReplicas

func (d *DaemonSetWorkload) AvailableReplicas() int32

type DeploymentWorkload

type DeploymentWorkload struct {
	*v1.Deployment
}

func (*DeploymentWorkload) AvailableReplicas

func (d *DeploymentWorkload) AvailableReplicas() int32

type PodWorkload

type PodWorkload struct {
	Name      string       `json:"name"`
	Namespace string       `json:"namespace"`
	Kind      WorkloadKind `json:"kind"`
}

PodWorkload represents the higher-level controller managing a specific Pod within a Kubernetes cluster. It contains essential details about the controller such as its Name, Namespace, and Kind. 'Kind' refers to the type of controller, which can be a Deployment, StatefulSet, or DaemonSet. This struct is useful for identifying and interacting with the overarching entity that governs the lifecycle and behavior of a Pod, especially in contexts where understanding the relationship between a Pod and its controlling workload is crucial.

type StatefulSetWorkload

type StatefulSetWorkload struct {
	*v1.StatefulSet
}

func (*StatefulSetWorkload) AvailableReplicas

func (s *StatefulSetWorkload) AvailableReplicas() int32

type Workload

type Workload interface {
	client.Object
	AvailableReplicas() int32
}

func ObjectToWorkload

func ObjectToWorkload(obj client.Object) (Workload, error)

type WorkloadKind

type WorkloadKind string

1. the pascal case representation of the workload kind it is used in k8s api objects as the `Kind` field.

const (
	WorkloadKindDeployment  WorkloadKind = "Deployment"
	WorkloadKindDaemonSet   WorkloadKind = "DaemonSet"
	WorkloadKindStatefulSet WorkloadKind = "StatefulSet"
)

func ExtractWorkloadInfoFromRuntimeObjectName

func ExtractWorkloadInfoFromRuntimeObjectName(runtimeObjectName string) (workloadName string, workloadKind WorkloadKind, err error)

func GetWorkloadFromOwnerReference

func GetWorkloadFromOwnerReference(ownerReference metav1.OwnerReference) (workloadName string, workloadKind WorkloadKind, err error)

GetWorkloadFromOwnerReference retrieves both the workload name and workload kind from the provided owner reference.

func GetWorkloadNameAndKind

func GetWorkloadNameAndKind(ownerName, ownerKind string) (string, WorkloadKind, error)

func WorkloadKindFromClientObject

func WorkloadKindFromClientObject(w client.Object) WorkloadKind

func WorkloadKindFromLowerCase

func WorkloadKindFromLowerCase(lowerCase WorkloadKindLowerCase) WorkloadKind

func WorkloadKindFromString

func WorkloadKindFromString(kind string) WorkloadKind

type WorkloadKindLowerCase

type WorkloadKindLowerCase string

2. the lower case representation of the workload kind is used in odigos with the object name for instrumentation config and runtime details

const (
	WorkloadKindLowerCaseDeployment  WorkloadKindLowerCase = "deployment"
	WorkloadKindLowerCaseDaemonSet   WorkloadKindLowerCase = "daemonset"
	WorkloadKindLowerCaseStatefulSet WorkloadKindLowerCase = "statefulset"
)

func WorkloadKindLowerCaseFromKind

func WorkloadKindLowerCaseFromKind(pascalCase WorkloadKind) WorkloadKindLowerCase
