Functions

func AgentContainer

func AgentContainer(pod *core.Pod) *core.Container

AgentContainer returns the pod's traffic-agent container, or nil if the pod doesn't have a traffic-agent.

func Base26

func Base26(v uint64) string

Base26 converts the given number into base 26, represented using the letters 'a' to 'z'.

func CapsBase26

func CapsBase26(v uint64) string

CapsBase26 converts the given number into base 26, represented using the letters 'A' to 'Z'.

func FindOwnerWorkload

func FindOwnerWorkload(ctx context.Context, obj k8sapi.Object, supportedWorkloadKinds []string) (k8sapi.Workload, error)

func FindServicesForPod

func FindServicesForPod(ctx context.Context, pod *core.PodTemplateSpec, svcName string) ([]k8sapi.Object, error)

func GetWorkload

func GetWorkload(ctx context.Context, name, namespace, workloadKind string) (obj k8sapi.Workload, err error)

func InitContainer

func InitContainer(pod *core.Pod) *core.Container

InitContainer returns the pod's tel-agent-init init-container, or nil if the pod doesn't have a tel-agent-init.

func IsPodRunning

func IsPodRunning(pod *core.Pod) bool

IsPodRunning returns true if at least one container has state Running and a non-zero StartedAt.
