func Run

func Run(ctx context.Context, namespace string, clientset *kubernetes.Clientset) error

Run starts the main run loop

func Watch

func Watch(ctx context.Context, i v1.PodInterface, podFilter *regexp.Regexp, containerFilter *regexp.Regexp, containerState ContainerState, labelSelector labels.Selector) (chan *Target, chan *Target, error)

Watch starts listening to Kubernetes events and emits modified containers/pods. The first result is targets added, the second is targets removed

func NewContainerState

func NewContainerState(stateConfig string) (ContainerState, error)

func (ContainerState) Match

func (stateConfig ContainerState) Match(containerState v1.ContainerState) bool

type Tail

type Tail struct {
	Namespace     string
	PodName       string
	ContainerName string
	// contains filtered or unexported fields
}

func NewTail

func NewTail(namespace, podName, containerName string) *Tail

NewTail returns a new tail for a Kubernetes container inside a pod

func (*Tail) Close

func (t *Tail) Close()

type Target

type Target struct {
	Namespace string
	Pod       string
	Container string
}

Target is a target to watch

func (*Target) GetID
