}

CCEEndpointGetterUpdater defines the interface used to interact with the k8s apiserver to retrieve and update the CCEEndpoint custom resource

type DirectAllocatorStarter 

type DirectAllocatorStarter interface {
	StartEndpointManager(ctx context.Context, getterUpdater CCEEndpointGetterUpdater) (EndpointEventHandler, error)
}

DirectAllocatorStarter is the interface an IPAM implementation must provide in order

type DirectEndpointOperation 

type DirectEndpointOperation interface {
	// FilterAvailableSubnet returns the best subnet for the endpoint
	FilterAvailableSubnet([]*ccev1.Subnet) []*ccev1.Subnet

	// AllocateIP allocates an IP for the endpoint
	// The meaning of reusing the IP address is to migrate the IP
	// address to be used by the pod from one node to another
	// if action.addressing is not nil, it means that the IP address is reused
	// if action.addressing is nil, it means that the IP address is newly allocated
	// Note: This method will be called repeatedly, and the implementer must support reentrant calls
	AllocateIP(ctx context.Context, action *DirectIPAction) error

	// DeleteIP When the fixed IP pod is recycled and the IP is no longer reused,
	// for example, the workload is permanently deleted. At this time, the fixed
	// the implement should only delete the IP address while its owner is euqal to action.owner
	// IP that should be retained should be recycled.
	DeleteIP(ctx context.Context, allocation *DirectIPAction) error
}

type DirectIPAction 

type DirectIPAction struct {
	// NodeName is identifier describing the ip on which node
	NodeName string

	Owner string

	// IP4/6 addresses assigned to this Endpoint
	// this field used to dynamic allocate ip
	// +optional
	SubnetID string

	// IP4/6 addresses assigned to this Endpoint
	Addressing ccev2.AddressPairList

	// Interface is the identifier describing the ip on which interface
	// this field used as param to release ip
	// +optional
	Interface string

	// A list of node selector requirements by node's labels.
	// +optional
	NodeSelectorRequirement []corev1.NodeSelectorRequirement `json:"matchExpressions,omitempty" protobuf:"bytes,1,rep,name=matchExpressions"`
}

type DirectIPAllocator 

type DirectIPAllocator interface {
	// ResyncPool is called to synchronize the latest list of interfaces and IPs
	ResyncPool(ctx context.Context, scopedLog *logrus.Entry) (map[string]ipamTypes.AllocationMap, error)

	// NodeEndpoint returns the NodeEndpointOperation
	NodeEndpoint(cep *ccev2.CCEEndpoint) (DirectEndpointOperation, error)
}

DirectIPAllocator is the interface an IPAM implementation must provide in order to provide IP allocation for a node. The structure implementing this API *must* be aware of the node connected to this implementation. This is achieved by considering the node context provided in AllocationImplementation.CreateNetResource() function and returning a NodeOperations implementation which performs operations in the context of that node.

type DirectIPAllocatorProvider 

type DirectIPAllocatorProvider interface {
	Init(ctx context.Context) error
	StartEndpointManager(ctx context.Context, getterUpdater CCEEndpointGetterUpdater) (EndpointEventHandler, error)
}

DirectIPAllocatorProvider defines the functions of IPAM provider front-end these are implemented by e.g. pkg/ipam/allocator/{privatecloudbase}.

type EndpointAPIHandler 

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

EndpointAPIHandler is the handler for the endpoint API.

func NewEndpointAPIHandler 

func NewEndpointAPIHandler(watcher *watchers.K8sWatcher) *EndpointAPIHandler

func (*EndpointAPIHandler) GetEndpointExtpluginStatus 

func (handler *EndpointAPIHandler) GetEndpointExtpluginStatus(ctx context.Context, namespace, name, containerID string) (models.ExtFeatureData, error)

type EndpointAllocator 

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

EndpointAllocator It proxies the basic operation methods of ipam. Each time an IP application succeeds, a CCEEndpoint object will be created. During gc, the existing CCEEndpoint objects will be gc based on CCEEndpoint

func (*EndpointAllocator) ADD 

func (e *EndpointAllocator) ADD(family, owner, containerID, netns string) (ipv4Result, ipv6Result *ipam.AllocationResult, err error)

ADD allocates an IP for the given owner and returns the allocated IP.

func (*EndpointAllocator) Dump 

func (e *EndpointAllocator) Dump() (allocv4 map[string]string, allocv6 map[string]string, status string)

func (*EndpointAllocator) Restore 

func (e *EndpointAllocator) Restore()

Restore all the IP addresses applied for by the current machine to the node cache pool

func (*EndpointAllocator) RestoreFinished 

func (e *EndpointAllocator) RestoreFinished()

type EndpointEventHandler 

type EndpointEventHandler interface {
	Create(resource *ccev2.CCEEndpoint) error
	Update(resource *ccev2.CCEEndpoint) error
	Delete(namespace, endpointName string) error
	Resync(context.Context) error
}

EndpointEventHandler should implement the behavior to handle CCEEndpoint

type EndpointManager 

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

func NewEndpointManager 

func NewEndpointManager(getterUpdater CCEEndpointGetterUpdater, reuseIPImplement DirectIPAllocator) *EndpointManager

func (*EndpointManager) Create

func (manager *EndpointManager) Resync(ctx context.Context) error

func (*EndpointManager) Start 

func (manager *EndpointManager) Start(ctx context.Context) error

Start kicks of the NodeManager by performing the initial state synchronization and starting the background sync go routine

func (*EndpointManager) Update 

func (manager *EndpointManager) Update(resource *ccev2.CCEEndpoint) error

type EndpointMunalAllocatorProvider 

type EndpointMunalAllocatorProvider interface {
	AllocateIP(ctx context.Context, log *logrus.Entry, resource *ccev2.CCEEndpoint) error
}

type K8sEventRegister 

type K8sEventRegister interface {
	// K8sEventReceived is called to do metrics accounting for received
	// Kubernetes events, as well as calculating timeouts for k8s watcher
	// cache sync.
	K8sEventReceived(apiGroupResourceName string, scope string, action string, valid, equal bool)

	// K8sEventProcessed is called to do metrics accounting for each processed
	// Kubernetes event.
	K8sEventProcessed(scope string, action string, status bool)

	// RegisterNetResourceSetSubscriber allows registration of subscriber.NetResourceSet
	// implementations. Events for all NetResourceSet events (not just the local one)
	// will be sent to the subscriber.
	RegisterNetResourceSetSubscriber(s subscriber.NetResourceSet)
}

K8sEventRegister is used to register and handle events as they are processed by K8s controllers.
