Functions

func GetLoadBalancerSourceRanges

func GetLoadBalancerSourceRanges(service *v1.Service) (utilnet.IPNetSet, 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 GetServiceHealthCheckPathPort

func GetServiceHealthCheckPathPort(service *v1.Service) (string, int32)

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

func HasLBFinalizer

func HasLBFinalizer(service *v1.Service) bool

HasLBFinalizer checks if service contains LoadBalancerCleanupFinalizer.

func IsAllowAll

func IsAllowAll(ipnets utilnet.IPNetSet) bool

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

func LoadBalancerStatusEqual

func LoadBalancerStatusEqual(l, r *v1.LoadBalancerStatus) bool

LoadBalancerStatusEqual checks if load balancer status are equal

func NeedsHealthCheck

func NeedsHealthCheck(service *v1.Service) bool

NeedsHealthCheck checks if service needs health check.

func PatchService

func PatchService(c corev1.CoreV1Interface, oldSvc, newSvc *v1.Service) (*v1.Service, error)

PatchService patches the given service's Status or ObjectMeta based on the original and updated ones. Change to spec will be ignored.

func RequestsOnlyLocalTraffic

func RequestsOnlyLocalTraffic(service *v1.Service) bool

RequestsOnlyLocalTraffic checks if service requests OnlyLocal traffic.
