Types

type Handler 

type Handler interface {
	// Init is called once on startup to let the handler initialize any state it needs.
	Init() error

	// GetName returns the name of the event handler
	GetName() string

	// GetNetworkPlugin returns the kubernetes network plugin that this handler supports.
	GetNetworkPlugins() []string

	// Stop is called once during shutdown to let the handler perform any cleanup. The uninstall flag indicates
	// whether or not Submariner is being completely uninstalled from the system.
	Stop(uninstall bool) error

	// TransitionToNonGateway is called once for each transition of the local node from Gateway to a non-Gateway.
	TransitionToNonGateway() error

	// TransitionToGateway is called once for each transition of the local node from non-Gateway to a Gateway.
	TransitionToGateway() error

	// LocalEndpointCreated is called when an endpoint for the local cluster is created.
	LocalEndpointCreated(endpoint *submV1.Endpoint) error

	// LocalEndpointUpdated is called when an endpoint for the local cluster is updated.
	LocalEndpointUpdated(endpoint *submV1.Endpoint) error

	// LocalEndpointRemoved is called when an endpoint for the local cluster is removed.
	LocalEndpointRemoved(endpoint *submV1.Endpoint) error

	// RemoteEndpointCreated is called when an endpoint associated with a remote cluster is created.
	RemoteEndpointCreated(endpoint *submV1.Endpoint) error

	// RemoteEndpointUpdated is called when an endpoint associated with a remote cluster is updated.
	RemoteEndpointUpdated(endpoint *submV1.Endpoint) error

	// RemoteEndpointRemoved is called when an endpoint associated with a remote cluster is removed
	RemoteEndpointRemoved(endpoint *submV1.Endpoint) error

	// NodeCreated indicates when a node has been added to the cluster
	NodeCreated(node *k8sV1.Node) error

	// NodeUpdated indicates when a node has been updated in the cluster
	NodeUpdated(node *k8sV1.Node) error

	// NodeRemoved indicates when a node has been removed from the cluster
	NodeRemoved(node *k8sV1.Node) error
