NamedPortOperation decides opeartion (e.g., delete or add) for named port ipset in manageNamedPortIpsets

const (
	DeleteNamedPortIpsets NamedPortOperation = "del"
	AddNamedPortIpsets    NamedPortOperation = "add"
)

type Namespace

type Namespace struct {
	LabelsMap map[string]string // NameSpace labels
	SetMap    map[string]string
	IpsMgr    *ipsm.IpsetManager
	// contains filtered or unexported fields
}

type NetworkPolicyManager

type NetworkPolicyManager struct {
	sync.Mutex

	Exec utilexec.Interface

	NodeName       string
	NsMap          map[string]*Namespace                  // Key is ns-<nsname>
