Types

type NodeDiscovery

type NodeDiscovery struct {
	Manager     nodemanager.NodeManager
	LocalConfig datapath.LocalNodeConfiguration
	Registrar   nodestore.NodeRegistrar
	Registered  chan struct{}

	NetConf *cnitypes.NetConf
	// contains filtered or unexported fields
}

NodeDiscovery represents a node discovery action

func NewNodeDiscovery

func NewNodeDiscovery(manager nodemanager.NodeManager, clientset client.Clientset, mtuConfig mtu.Configuration, netConf *cnitypes.NetConf) *NodeDiscovery

NewNodeDiscovery returns a pointer to new node discovery object

func (*NodeDiscovery) ClusterSizeDependantInterval

func (n *NodeDiscovery) ClusterSizeDependantInterval(baseInterval time.Duration) time.Duration

func (*NodeDiscovery) JoinCluster

func (n *NodeDiscovery) JoinCluster(nodeName string)

JoinCluster passes the node name to the kvstore and updates the local configuration on response. This allows cluster configuration to override local configuration. Must be called on agent startup after IPAM is configured, but before the configuration is used. nodeName is the name to be used in the local agent.

func (*NodeDiscovery) LocalAllocCIDRsUpdated

func (n *NodeDiscovery) LocalAllocCIDRsUpdated(ipv4AllocCIDRs, ipv6AllocCIDRs []*cidr.CIDR)

LocalAllocCIDRsUpdated informs the agent that the local allocation CIDRs have changed. This will inform the datapath node manager to update the local node routes accordingly. The first CIDR in ipv[46]AllocCIDRs is presumed to be the primary CIDR: This CIDR remains assigned to the local node and may not be switched out or be removed.

func (*NodeDiscovery) LocalNode

func (n *NodeDiscovery) LocalNode() *types.Node

LocalNode syncs the localNode object with the information stored in the node package and then returns a copy of the localNode object

func (*NodeDiscovery) NodeDeleted

func (n *NodeDiscovery) NodeDeleted(node nodeTypes.Node)

func (*NodeDiscovery) NodeUpdated

func (n *NodeDiscovery) NodeUpdated(node nodeTypes.Node)

func (*NodeDiscovery) RegisterK8sGetters

func (n *NodeDiscovery) RegisterK8sGetters(k8sGetters k8sGetters)

func (*NodeDiscovery) StartDiscovery

func (n *NodeDiscovery) StartDiscovery()

start configures the local node and starts node discovery. This is called on agent startup to configure the local node based on the configuration options passed to the agent. nodeName is the name to be used in the local agent.

func (*NodeDiscovery) UpdateCiliumNodeResource

func (n *NodeDiscovery) UpdateCiliumNodeResource()

UpdateCiliumNodeResource updates the CiliumNode resource representing the local node

func (*NodeDiscovery) UpdateLocalNode

func (n *NodeDiscovery) UpdateLocalNode()

UpdateLocalNode syncs the internal localNode object with the actual state of the local node and publishes the corresponding updated KV store entry and/or CiliumNode object

func (*NodeDiscovery) WaitForLocalNodeInit

func (n *NodeDiscovery) WaitForLocalNodeInit()

WaitForLocalNodeInit blocks until StartDiscovery() has been called. This is used to block until Node's local IP addresses have been allocated, see https://github.com/go-faster/cilium/pull/14299 and https://github.com/go-faster/cilium/pull/14670.
