Functions

func AllowTigeraDefaultDeny

func AllowTigeraDefaultDeny(namespace string) *v3.NetworkPolicy

func AppendDNSEgressRules

func AppendDNSEgressRules(egressRules []v3.Rule, openShift bool) []v3.Rule

AppendDNSEgressRules appends a rule to the provided slice that allows DNS egress. The appended rule utilizes label selectors and ports.

func AppendServiceSelectorDNSEgressRules

func AppendServiceSelectorDNSEgressRules(egressRules []v3.Rule, openShift bool) []v3.Rule

AppendServiceSelectorDNSEgressRules is equivalent to AppendDNSEgressRules, utilizing service selector instead of label selector and ports.

func CreateEntityRule

func CreateEntityRule(namespace string, deploymentName string, ports ...uint16) v3.EntityRule

CreateEntityRule creates an entity rule that matches traffic using label selectors based on namespace, deployment name, and port.

func CreateServiceSelectorEntityRule

func CreateServiceSelectorEntityRule(namespace string, name string) v3.EntityRule

CreateServiceSelectorEntityRule creates an entity rule that matches traffic based on service name and namespace.

func CreateSourceEntityRule

func CreateSourceEntityRule(namespace string, deploymentName string) v3.EntityRule

CreateSourceEntityRule creates a conventional entity rule that matches ingress traffic based on namespace and deployment name.

func KubernetesAppSelector

func KubernetesAppSelector(deploymentNames ...string) string

func Ports

func Ports(ports ...uint16) []numorstring.Port
