Types

type AddressGroup

type AddressGroup struct {
	SpanMeta
	// UID is generated from the hash value of GroupSelector.NormalizedName.
	UID types.UID
	// Name of this group, currently it's same as UID.
	Name string
	// Selector describes how the group selects pods to get their addresses.
	Selector GroupSelector
	// Pods is a set of Pods selected by this group.
	// It will be converted to a slice of GroupMemberPod for transferring according
	// to client's selection.
	Pods networking.GroupMemberPodSet
}

AddressGroup describes a set of addresses used as source or destination of Network Policy rules.

type AppliedToGroup

type AppliedToGroup struct {
	SpanMeta
	// UID is generated from the hash value of GroupSelector.NormalizedName.
	UID types.UID
	// Name of this group, currently it's same as UID.
	Name string
	// Selector describes how the group selects pods.
	Selector GroupSelector
	// PodsByNode is a mapping from nodeName to a set of Pods on the Node.
	// It will be converted to a slice of GroupMemberPod for transferring according
	// to client's selection.
	PodsByNode map[string]networking.GroupMemberPodSet
}

AppliedToGroup describes a set of Pods to apply Network Policies to.

type GroupSelector

type GroupSelector struct {
	// The normalized name is calculated from Namespace, PodSelector, and NamespaceSelector.
	// If multiple policies have same selectors, they should share this group by comparing NormalizedName.
	// It's also used to generate Name and UUID of group.
	NormalizedName string
	// If Namespace is set, NamespaceSelector can not be set. It means only Pods in this Namespace will be matched.
	Namespace string
	// This is a label selector which selects Pods. If Namespace is also set, it selects the Pods in the Namespace.
	// If NamespaceSelector is also set, it selects the Pods in the Namespaces selected by NamespaceSelector.
	// If Namespace and NamespaceSelector both are unset, it selects the Pods in all the Namespaces.
	PodSelector labels.Selector
	// This is a label selector which selects Namespaces. It this field is set, Namespace can not be set.
	NamespaceSelector labels.Selector
}

GroupSelector describes how to select Pods.

type NetworkPolicy

type NetworkPolicy struct {
	SpanMeta
	// UID of the original K8s Network Policy.
	UID types.UID
	// Name of the original K8s Network Policy.
	Name string
	// Namespace of the original K8s Network Policy.
	// An empty value indicates that the Network Policy is Cluster scoped.
	Namespace string
	// Priority represents the relative priority of this Network Policy as compared to
	// other Network Policies. Priority will be unset (nil) for K8s Network Policy.
	Priority *float64
	// Rules is a list of rules to be applied to the selected Pods.
	Rules []networking.NetworkPolicyRule
	// AppliedToGroups is a list of names of AppliedToGroups to which this policy applies.
	AppliedToGroups []string
	// TierPriority represents the priority of the Tier associated with this Network
	// Policy.
	TierPriority *networking.TierPriority
}

NetworkPolicy describes what network traffic is allowed for a set of Pods.

type Span

type Span interface {
	Has(nodeName string) bool
}

Span provides methods to work with SpanMeta and objects composed of it.

type SpanMeta

type SpanMeta struct {
	// NodeNames is a set of node names that this object should be sent to.
	NodeNames sets.String
}

SpanMeta describes the span information of an object.

func (*SpanMeta) Has

func (meta *SpanMeta) Has(nodeName string) bool
