Constants ¶
const ( LeaderElectionEnabled = "enabled" LeaderElectionDisabled = "disabled" )
const DiagnosticsPort = 10256
    DiagnosticsPort is the default port of the manager's diagnostics service listens on.
const HealthzPort = 10254
    HealthzPort is the default port the manager's health service listens on. Changing this will result in a breaking change. Existing deployments may use the literal port number in their liveness and readiness probes, and upgrading to a controller version with a changed HealthzPort will result in crash loops until users update their probe config. Note that there are several stock manifests in this repo that also use the literal port number. If you update this value, search for the old port number and update the stock manifests also.
const KongClientEventRecorderComponentName = "kong-client"
    KongClientEventRecorderComponentName is a KongClient component name used to identify the events recording component.
const MetricsPort = 10255
    MetricsPort is the default port the manager's metrics service listens on. Similar to HealthzPort, it may be used in existing user deployment configurations, and its literal value is used in several stock manifests, which must be updated along with this value.

Functions ¶
func AdminAPIClientFromServiceDiscovery ¶
func AdminAPIClientFromServiceDiscovery( ctx context.Context, logger logr.Logger, kongAdminSvcNN k8stypes.NamespacedName, kubeClient client.Client, discoverer AdminAPIsDiscoverer, factory AdminAPIClientFactory, retryOpts ...retry.Option, ) ([]*adminapi.Client, error)
func Run ¶
func Run( ctx context.Context, c *Config, diagnostic diagnostics.ConfigDumpDiagnostic, logger logr.Logger, ) error
Run starts the controller manager and blocks until it exits.

    Config collects all configuration that the controller manager takes from the environment.
type ConfigOpt ¶ added in v3.2.0
type ConfigOpt func(*Config)
ConfigOpt is a function that modifies a Config.
type Controller ¶
Controller is a Kubernetes controller that can be plugged into Manager.

GatewayClientsProvider is an interface that provides clients for the currently discovered Gateway instances.
type InstanceIDProvider ¶
type InstanceIDProvider struct {
	// contains filtered or unexported fields
}
    InstanceIDProvider provides a unique identifier for a running instance of the manager. It should be used by all components that register the instance in any external system.

func NewInstanceIDProvider() *InstanceIDProvider
func (*InstanceIDProvider) GetID ¶
func (p *InstanceIDProvider) GetID() uuid.UUID

func (SchemaServiceGetter) GetSchemaService ¶ added in v3.2.0
func (ssg SchemaServiceGetter) GetSchemaService() kong.AbstractSchemaService
GetSchemaService returns the schema service for admin API client. It uses the configured clients manager to get the clients and then it uses one of those to obtain the service.
type TypeMetaSettingClient ¶
TypeMetaSettingClient decorates client.Client so that it populates the TypeMeta field of the object after fetching it from the API server.
