Constants

const (
	ANPFlowStartPriority = 30000
	ANPMaxRulesPerObject = 100

	BANPFlowPriority = 1750 // down to 1651 (both inclusive, note that these ACLs will be in tier3)
)

NOTE: Iteration v1 of ANP will only support upto 100 ANPs We will use priority range from 30000 (0) to 20000 (99) ACLs (both inclusive, note that these ACLs will be in tier1) In order to support more in the future, we will need to fix priority range in OVS See https://bugzilla.redhat.com/show_bug.cgi?id=2175752 for more details. NOTE: A cluster can have only BANP at a given time as defined by upstream KEP.

Functions

func GetACLActionForANPRule

func GetACLActionForANPRule(action anpapi.AdminNetworkPolicyRuleAction) string

GetACLActionForANPRule returns the corresponding OVN ACL action for a given ANP rule action

func GetACLActionForBANPRule

func GetACLActionForBANPRule(action anpapi.BaselineAdminNetworkPolicyRuleAction) string

GetACLActionForBANPRule returns the corresponding OVN ACL action for a given BANP rule action

func GetANPPeerAddrSetDbIDs

func GetANPPeerAddrSetDbIDs(name, gressPrefix, gressIndex, controller string, isBanp bool) *libovsdbops.DbObjectIDs

GetANPPeerAddrSetDbIDs will return the dbObjectIDs for a given rule's address-set

func GetANPPortGroupDbIDs

func GetANPPortGroupDbIDs(anpName string, isBanp bool, controller string) *libovsdbops.DbObjectIDs

Types

type Controller

type Controller struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Controller holds the fields required for ANP controller taken from k8s controller guidelines

func NewController

func NewController(
	controllerName string,
	nbClient libovsdbclient.Client,
	anpClient anpclientset.Interface,
	anpInformer anpinformer.AdminNetworkPolicyInformer,
	banpInformer anpinformer.BaselineAdminNetworkPolicyInformer,
	namespaceInformer corev1informers.NamespaceInformer,
	podInformer corev1informers.PodInformer,
	nodeInformer corev1informers.NodeInformer,
	addressSetFactory addressset.AddressSetFactory,
	isPodScheduledinLocalZone func(*v1.Pod) bool,
	zone string,
	recorder record.EventRecorder) (*Controller, error)

NewController returns a new *Controller.

func (*Controller) Run

func (c *Controller) Run(threadiness int, stopCh <-chan struct{})

Run will not return until stopCh is closed. workers determines how many objects (pods, namespaces, anps, banps) will be handled in parallel.
