Constants

const InhibitMaxDelay = 40 * constants.KubeletShutdownGracePeriod

InhibitMaxDelay is the maximum delay for graceful shutdown.

Types

type DBusBroker

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

DBusBroker implements simplified D-Bus broker which allows to connect kubelet D-Bus connection with Talos logind mock.

Broker doesn't actually implement auth, and it is supposed that service connects on one socket, while a client connects on another socket.

func NewBroker

func NewBroker(serviceSocketPath, clientSocketPath string) (*DBusBroker, error)

NewBroker initializes new broker.

func (*DBusBroker) Close

func (broker *DBusBroker) Close() error

Close the listen sockets.

func (*DBusBroker) Run

func (broker *DBusBroker) Run(ctx context.Context) error

Run the broker.

type ServiceMock

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

ServiceMock connects to the broker and mocks the D-Bus and logind.

func NewServiceMock

func NewServiceMock(socketPath string) (*ServiceMock, error)

NewServiceMock initializes the D-Bus and logind mock.

func (*ServiceMock) Close

func (mock *ServiceMock) Close() error

Close the connection.

func (*ServiceMock) EmitShutdown

func (mock *ServiceMock) EmitShutdown() error

EmitShutdown notifies about the shutdown.

func (*ServiceMock) WaitLockRelease

func (mock *ServiceMock) WaitLockRelease(ctx context.Context) error

WaitLockRelease waits for the inhibit lock to be released.
