const (
	// DiagnosticConfigBufferDepth is the size of the channel buffer for receiving diagnostic
	// config dumps from the proxy sync loop. The chosen size is essentially arbitrary: we don't
	// expect that the receive end will get backlogged (it only assigns the value to a local
	// variable) but do want a small amount of leeway to account for goroutine scheduling, so it
	// is not zero.
	DiagnosticConfigBufferDepth = 3

Functions ¶

func Execute ¶

func Execute()

Execute is the entry point to the controller manager.

func GetRootCmd ¶

func GetRootCmd(cfg *manager.Config) *cobra.Command

func GetVersionCmd ¶

func GetVersionCmd() *cobra.Command

func Run ¶

func Run(ctx context.Context, c *manager.Config, output io.Writer) error

Run sets up a default stderr logger and starts the controller manager.

func RunWithLogger ¶

func RunWithLogger(ctx context.Context, c *manager.Config, logger logr.Logger) error

RunWithLogger starts the controller manager with a provided logger.

func SetupSignalHandler ¶

func SetupSignalHandler(ctx context.Context, cfg *manager.Config, logger logr.Logger) (context.Context, error)

SetupSignalHandler registers for SIGTERM and SIGINT. A context is returned which is canceled on one of these signals. If a second signal is not caught, the program will delay for the configured period of time before terminating. If a second signal is caught, the program is terminated with exit code 1.

func StartDiagnosticsServer ¶

func StartDiagnosticsServer(
	ctx context.Context,
	port int,
	c *manager.Config,
	logger logr.Logger,
) (diagnostics.Server, error)

StartDiagnosticsServer starts a goroutine that handles requests for the diagnostics server.
