Functions

func BuildClusterName

func BuildClusterName(direction TrafficDirection, subsetName, hostname string, port int) string

BuildClusterName the cluster name referencing service instances for a given service name, a subset and a port, which is the same as the cluster name generated by Istio.

func BuildMetaProtocolRouteName

func BuildMetaProtocolRouteName(host string, port int) string

BuildMetaProtocolRouteName the route name for a given metaProtocol service

func GetHashPolicy

func GetHashPolicy(dr *DestinationRuleWrapper, subsetName string) string

GetHashPolicy return consistent hash policy in dr it will be overridden if subset named as subsetName in param is not nil

func IsFQDNEquals

func IsFQDNEquals(name1, ns1, name2, ns2 string) bool

IsFQDNEquals return true if two FQDN name equals, false if not

func Struct2JSON

func Struct2JSON(ojb interface{}) interface{}

Struct2JSON convert a go struct to a json object

Types

type DestinationRuleWrapper

type DestinationRuleWrapper struct {
	istioconfig.Meta
	Spec *networking.DestinationRule
}

DestinationRuleWrapper wraps an Istio DestinationRule and its metadata, including name, annotations and labels.

type EnvoyFilterContext

type EnvoyFilterContext struct {

	// Global Mesh config
	MeshConfig mesh.Holder

	// Gateway describes the gateway for which we need to generate the EnvoyFilter.
	// ServiceEntry will be ignored when this field specified.
	Gateway *GatewayWrapper

	// ServiceEntry describes the service for which we need to generate the EnvoyFilter.
	ServiceEntry *ServiceEntryWrapper

	// VirtualService is the related VirtualService of the ServiceEntry, which defines the routing rules for the service.
	// Only one VirtualService is allowed for a Service.
	// The value of VirtualService is nil in case that no VirtualService defined for the service.
	VirtualService *VirtualServiceWrapper

	// VirtualService is the related VirtualService of the ServiceEntry, which defines the routing rules for the service.
	// Only one VirtualService is allowed for a Service.
	// The value of VirtualService is nil in case that no VirtualService defined for the service.
	MetaRouter *metaprotocol.MetaRouter
}

EnvoyFilterContext provides an aggregate API for EnvoyFilter generator

type EnvoyFilterWrapper

type EnvoyFilterWrapper struct {
	Name        string
	Namespace   string
	Envoyfilter *networking.EnvoyFilter
}

EnvoyFilterWrapper wraps an Istio EnvoyFilterWrapper and its name, which is used as an unique identifier in Istio. If two Envoyfilters with the same name have been created, the previous one sill be replaced by the latter one

type GatewayWrapper

type GatewayWrapper struct {
	istioconfig.Meta
	Spec *networking.Gateway
}

GatewayWrapper wraps an Istio Gateway and its metadata, including name, annotations and labels.

type ServiceEntryWrapper

type ServiceEntryWrapper struct {
	istioconfig.Meta
	Spec *networking.ServiceEntry
}

ServiceEntryWrapper wraps an Istio ServiceEntry and its metadata, including name, annotations and labels. Meta can be used to pass in some additional information that is needed for EnvoyFilter generation. For example, we use an "interface" annotation to pass the dubbo interface to the Dubbo generator.

type TrafficDirection

type TrafficDirection string

TrafficDirection defines whether traffic exists a service instance or enters a service instance

const (
	// TrafficDirectionInbound indicates inbound traffic
	TrafficDirectionInbound TrafficDirection = "inbound"
	// TrafficDirectionOutbound indicates outbound traffic
	TrafficDirectionOutbound TrafficDirection = "outbound"
)

type VirtualServiceWrapper

type VirtualServiceWrapper struct {
	istioconfig.Meta
	Spec *networking.VirtualService
}

VirtualServiceWrapper wraps an Istio VirtualService and its metadata, including name, annotations and labels.
