Functions

func GetLoadBalancerSourceRanges

func GetLoadBalancerSourceRanges(service *api.Service) (netsets.IPNet, error)

GetLoadBalancerSourceRanges first try to parse and verify LoadBalancerSourceRanges field from a service. If the field is not specified, turn to parse and verify the AnnotationLoadBalancerSourceRangesKey annotation from a service, extracting the source ranges to allow, and if not present returns a default (allow-all) value.

func GetServiceHealthCheckNodePort

func GetServiceHealthCheckNodePort(service *api.Service) int32

GetServiceHealthCheckNodePort Return health check node port annotation for service, if one exists

func GetServiceHealthCheckPathPort

func GetServiceHealthCheckPathPort(service *api.Service) (string, int32)

GetServiceHealthCheckPathPort Return the path and nodePort programmed into the Cloud LB Health Check

func IsAllowAll

func IsAllowAll(ipnets netsets.IPNet) bool

IsAllowAll checks whether the netsets.IPNet allows traffic from 0.0.0.0/0

func NeedsHealthCheck

func NeedsHealthCheck(service *api.Service) bool

NeedsHealthCheck Check service for health check annotations
