Functions

func RegisterCallbacksAtInit

func RegisterCallbacksAtInit(cbs Callbacks)

RegisterCallbacksAtInit registers callbacks (should be called at init())

Types

type Callbacks

type Callbacks struct {
	CreateContainer func(ctx context.Context, arg *CreateContainerArg) error
}

type CreateContainerArg

type CreateContainerArg struct {
	Req     *v1.CreateContainer
	Watcher watcher.K8sResourceWatcher
}

type DummyHookRunner

type DummyHookRunner struct{}

func (DummyHookRunner) RunHooks

func (o DummyHookRunner) RunHooks(_ context.Context, _ *tetragon.RuntimeHookRequest) error

type Runner

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

func GlobalRunner

func GlobalRunner() *Runner

After RegisterCallbacksAtInit(), this function can be used to retrieve the Runner. Once this function is called, subsequent calls of RegisterCallbacksAtInit() will panic()

func (*Runner) RunHooks

func (r *Runner) RunHooks(ctx context.Context, req *v1.RuntimeHookRequest) error

runHooks executes all registered callbacks

func (*Runner) WithWatcher

func (r *Runner) WithWatcher(watcher watcher.K8sResourceWatcher) *Runner

WithWatcher sets the watcher on a runner
