Types ¶
type Assigner ¶
type Assigner interface {
EnsureAssigned(ctx context.Context, nodeAnnouncingByIP map[string]string) error
}
Assigner describes an interface which must be implemented by cloud platform specific implementation to assign Floating IP addresses to cluster nodes.
type Klogger ¶
type Klogger struct{}
Klogger is a default Logger interface implementation using klog.
func (Klogger) Debugf ¶
Debugf implements Logger interface using klog.Infof with log level defined by klogLevelDebug constant.
type Logger ¶
type Logger interface {
// Logger should implement writer interface for writing debug logs.
io.Writer
// Errorf should be used for logging non-critical (operational) failures.
Errorf(format string, a ...interface{})
// Infof should be used to log details about activity happening.
Infof(format string, a ...interface{})
// Debugf should be used to log as much details as possible.
Debugf(format string, a ...interface{})
}
Logger is an logging interface used by this controller. Default implementation is provided by Klogger struct, however other implementations can be configured and used.
type MetalLBHCloudControllerConfig ¶
type MetalLBHCloudControllerConfig struct {
// Path to kubeconfig file to use. If empty, either in-cluster kubeconfig file will
// be used or will fallback to use ~/.kube/config file.
KubeconfigPath string
// Logger implementation to use. If omitted, Klogger will be used.
Logger Logger
// Map of assigner implementations, where alternative assigner implementations can
// be added.
Assigners map[string]Assigner
// Channel on which controller will look for shutdown signal. If nil, channel will be
// initialized and it is up to the caller to close it.
StopCh <-chan struct{}
// Optional Prometheus Registerer to register controller metrics.
PrometheusRegistrer prometheus.Registerer
}
MetalLBHCloudControllerConfig is used to configure and run MetalLB Hetzner Cloud controller.
func (MetalLBHCloudControllerConfig) New ¶
func (cc MetalLBHCloudControllerConfig) New() (*metalLBHCloudController, error)
New Validates controller configuration and starts the controller.
