Functions

func CiliumEndpointsInit

func CiliumEndpointsInit(ctx context.Context, wg *sync.WaitGroup, clientset k8sClient.Clientset)

CiliumEndpointsInit starts a CiliumEndpointWatcher

func HandleNodeTolerationAndTaints

func HandleNodeTolerationAndTaints(wg *sync.WaitGroup, clientset k8sClient.Clientset, stopCh <-chan struct{}, logger *slog.Logger)

HandleNodeTolerationAndTaints remove node

func HasCE

func HasCE(ns, name string) (*cilium_api_v2.CiliumEndpoint, bool, error)

HasCE returns true or false if the Cilium Endpoint store has the endpoint with the given name.

func HasCiliumIsUpCondition

func HasCiliumIsUpCondition(n *slim_corev1.Node) bool

HasCiliumIsUpCondition returns true if the given k8s node has the cilium node condition set.

func RunCiliumNodeGC

func RunCiliumNodeGC(ctx context.Context, wg *sync.WaitGroup, clientset k8sClient.Clientset, ciliumNodeStore cache.Store, interval time.Duration, logger *slog.Logger)

RunCiliumNodeGC performs garbage collector for cilium node resource

func StartBGPBetaLBIPAllocator

func StartBGPBetaLBIPAllocator(ctx context.Context, clientset client.Clientset, services resource.Resource[*slim_corev1.Service], logger *slog.Logger)

StartBGPBetaLBIPAllocator starts the service watcher if it hasn't already and looks for service of type LoadBalancer. Once it finds a service of that type, it will try to allocate an external IP (LoadBalancerIP) for it.

func StartIPPoolAllocator

func StartIPPoolAllocator(
	ctx context.Context,
	clientset client.Clientset,
	allocator PooledAllocatorProvider,
	ipPools resource.Resource[*cilium_v2alpha1.CiliumPodIPPool],
	logger *slog.Logger,
)

func StartSynchronizingServices

func StartSynchronizingServices(ctx context.Context, wg *sync.WaitGroup, cfg ServiceSyncParameters, logger *slog.Logger)

StartSynchronizingServices starts a controller for synchronizing services from k8s to kvstore 'shared' specifies whether only shared services are synchronized. If 'false' then all services will be synchronized. For clustermesh we only need to synchronize shared services, while for VM support we need to sync all the services.

func TransformToUnmanagedPod

func TransformToUnmanagedPod(obj interface{}) (interface{}, error)

func UnmanagedPodsInit

func UnmanagedPodsInit(ctx context.Context, wg *sync.WaitGroup, clientset k8sClient.Clientset)

Types

type PooledAllocatorProvider

type PooledAllocatorProvider interface {
	UpsertPool(ctx context.Context, pool *cilium_v2alpha1.CiliumPodIPPool) error
	DeletePool(ctx context.Context, pool *cilium_v2alpha1.CiliumPodIPPool) error
}

PooledAllocatorProvider defines the functions of IPAM provider front-end which additionally allow definition of IP pools at runtime. This is implemented by e.g. pkg/ipam/allocator/multipool

type ServiceSyncParameters

type ServiceSyncParameters struct {
	ClusterInfo  cmtypes.ClusterInfo
	Clientset    k8sClient.Clientset
	Services     resource.Resource[*slim_corev1.Service]
	Endpoints    resource.Resource[*k8s.Endpoints]
	Backend      store.SyncStoreBackend
	SharedOnly   bool
	StoreFactory store.Factory
	SyncCallback func(context.Context)
}
