func NewEC2Wrapper

func NewEC2Wrapper(roleARN string, log logr.Logger) (EC2Wrapper, error)

NewEC2Wrapper takes the roleARN that will be assumed to make all the EC2 API Calls, if no roleARN is passed then the ec2 client will be initialized with the instance's service role account.

type ENICleaner

type ENICleaner struct {
	EC2Wrapper  EC2Wrapper
	ClusterName string
	Log         logr.Logger
	// contains filtered or unexported fields
}

func (*ENICleaner) SetupWithManager

func (e *ENICleaner) SetupWithManager(ctx context.Context, mgr ctrl.Manager) error

func (*ENICleaner) Start

func (e *ENICleaner) Start(ctx context.Context) error

StartENICleaner starts the ENI Cleaner routine that cleans up dangling ENIs created by the controller
