Documentation

Overview

This package contains the implementations of backend service features. For features that requrie non-GA compute API, please make sure to update `versionToFeatures` and `featuresFromServicePort()` in features.go (upon both feature addition and promotion). It will make sure the controller interacts with compute service using the proper API version.

Functions

func EnsureAffinity

func EnsureAffinity(sp utils.ServicePort, be *composite.BackendService) bool

EnsureAffinity reads the sessionAffinity and AffinityCookieTtlSec configuration specified in the ServicePort.BackendConfig and applies it to the BackendService. It returns true if there were existing settings on the BackendService that were overwritten.

func EnsureCDN

func EnsureCDN(sp utils.ServicePort, be *composite.BackendService) bool

EnsureCDN reads the CDN configuration specified in the ServicePort.BackendConfig and applies it to the BackendService. It returns true if there were existing settings on the BackendService that were overwritten.

func EnsureDraining

func EnsureDraining(sp utils.ServicePort, be *composite.BackendService) bool

EnsureDraining reads the ConnectionDraining configuration specified in the ServicePort.BackendConfig and applies it to the BackendService. It returns true if there were existing settings on the BackendService that were overwritten.

func EnsureIAP

func EnsureIAP(sp utils.ServicePort, be *composite.BackendService) bool

EnsureIAP reads the IAP configuration specified in the BackendConfig and applies it to the BackendService if it is stale. It returns true if there were existing settings on the BackendService that were overwritten.

func EnsureSecurityPolicy

func EnsureSecurityPolicy(cloud *gce.Cloud, sp utils.ServicePort, be *composite.BackendService, beName string) error

EnsureSecurityPolicy ensures the security policy link on backend service. TODO(mrhohn): Emit event when attach/detach security policy to backend service.

func EnsureTimeout

func EnsureTimeout(sp utils.ServicePort, be *composite.BackendService) bool

EnsureTimeout reads the TimeoutSec configuration specified in the ServicePort.BackendConfig and applies it to the BackendService. It returns true if there were existing settings on the BackendService that were overwritten.

func IsLowerVersion

func IsLowerVersion(v1, v2 meta.Version) bool

IsLowerVersion returns if v1 is a lower version than v2.

func SetDescription

func SetDescription(desc *utils.Description, sp *utils.ServicePort)

SetDescription sets the XFeatures field for the given Description.

func VersionFromDescription

func VersionFromDescription(desc string) meta.Version

VersionFromDescription returns the meta.Version required for the given description.

func VersionFromFeatures

func VersionFromFeatures(features []string) meta.Version

VersionFromFeatures returns the meta.Version required for the given list of features.

func VersionFromServicePort

func VersionFromServicePort(sp *utils.ServicePort) meta.Version

VersionFromServicePort returns the meta.Version for the backend that this ServicePort is associated with.
