This package contains the implementations of backend service features. For features that require 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 ¶ added in v1.4.0
func EnsureAffinity(sp utils.ServicePort, be *composite.BackendService, logger klog.Logger) 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, logger klog.Logger) 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 EnsureCustomRequestHeaders ¶ added in v1.7.0
func EnsureCustomRequestHeaders(sp utils.ServicePort, be *composite.BackendService, logger klog.Logger) bool
EnsureCustomRequestHeaders reads the CustomRequestHeaders 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 EnsureCustomResponseHeaders ¶ added in v1.20.0
func EnsureCustomResponseHeaders(sp utils.ServicePort, be *composite.BackendService, logger klog.Logger) bool
func EnsureDraining ¶ added in v1.4.0
func EnsureDraining(sp utils.ServicePort, be *composite.BackendService, logger klog.Logger) 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, beLogger klog.Logger) (bool, error)
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 EnsureLogging ¶ added in v1.9.1
func EnsureLogging(sp utils.ServicePort, be *composite.BackendService, logger klog.Logger) bool
EnsureLogging reads the log configurations 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 EnsureSecurityPolicy ¶
func EnsureSecurityPolicy(cloud *gce.Cloud, sp utils.ServicePort, be *composite.BackendService, logger klog.Logger) error
EnsureSecurityPolicy ensures the security policy link on backend service. TODO(mrhohn): Emit event when attach/detach security policy to backend service.
func EnsureTimeout ¶ added in v1.4.0
func EnsureTimeout(sp utils.ServicePort, be *composite.BackendService, logger klog.Logger) 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 ¶
IsLowerVersion returns if v1 is a lower version than v2.
func ScopeFromFeatures ¶ added in v1.7.0
ScopeFromFeatures returns the meta.KeyType required for the given list of features (e.g.) if a regional feature is added, the backend will be regional TODO: (shance) refactor all scope to be above the serviceport level
func ScopeFromServicePort ¶ added in v1.7.0
func ScopeFromServicePort(sp *utils.ServicePort) meta.KeyType
ScopeFromServicePort returns the meta.KeyType for the backend that this ServicePort is associated with TODO: (shance) refactor all scope to be above the serviceport level
func SetDescription ¶
func SetDescription(desc *utils.Description, sp *utils.ServicePort)
SetDescription sets the XFeatures field for the given Description.
func VersionFromDescription ¶
VersionFromDescription returns the meta.Version required for the given description.
func VersionFromFeatures ¶
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.
