Functions

func CompareLinks

func CompareLinks(l1, l2 string) bool

CompareLinks returns true if the 2 self links are equal.

func IsHTTPErrorCode

func IsHTTPErrorCode(err error, code int) bool

IsHTTPErrorCode checks if the given error matches the given HTTP Error code. For this to work the error must be a googleapi Error.

Types

type FakeIngressRuleValueMap

type FakeIngressRuleValueMap map[string]string

FakeIngressRuleValueMap is a convenience type used by multiple submodules that share the same testing methods.

type GCEURLMap

type GCEURLMap map[string]map[string]*compute.BackendService

GCEURLMap is a nested map of hostname->path regex->backend

func (GCEURLMap) GetDefaultBackend

func (g GCEURLMap) GetDefaultBackend() *compute.BackendService

GetDefaultBackend performs a destructive read and returns the default backend of the urlmap.

func (GCEURLMap) PutDefaultBackend

func (g GCEURLMap) PutDefaultBackend(d *compute.BackendService)

PutDefaultBackend performs a destructive write replacing the default backend of the url map with the given backend.

func (GCEURLMap) String

func (g GCEURLMap) String() string

String implements the string interface for the GCEURLMap.

type Namer

type Namer struct {
	ClusterName string
}

Namer handles centralized naming for the cluster.

func (*Namer) BeName

func (n *Namer) BeName(port int64) string

BeName constructs the name for a backend.

func (*Namer) IGName

func (n *Namer) IGName() string

IGName constructs the name for an Instance Group.

func (*Namer) LBName

func (n *Namer) LBName(key string) string

LBName constructs a loadbalancer name from the given key. The key is usually the namespace/name of a Kubernetes Ingress.

func (*Namer) Truncate

func (n *Namer) Truncate(key string) string

Truncate truncates the given key to a GCE length limit.
