Functions

func CheckForDuplicateFilterChainMatches added in v1.4.13

func CheckForDuplicateFilterChainMatches(filterChains []*envoy_config_listener_v3.FilterChain, listenerReport *validationapi.ListenerReport)

Check for identical FilterChains to avoid the envoy error that occurs here: https://github.com/envoyproxy/envoy/blob/v1.15.0/source/server/filter_chain_manager_impl.cc#L162-L166 Note: this is NOT address non-equal but overlapping FilterChainMatches, which is a separate check here: https://github.com/envoyproxy/envoy/blob/50ef0945fa2c5da4bff7627c3abf41fdd3b7cffd/source/server/filter_chain_manager_impl.cc#L218-L354 Given the complexity of the overlap detection implementation, we don't want to duplicate that behavior here. We may want to consider invoking envoy from a library to detect overlapping and other issues, which would build off this discussion: https://github.com/solo-io/gloo/issues/2114 Visible for testing

func ClusterToUpstreamRef added in v1.6.10

func ClusterToUpstreamRef(cluster string) (*core.ResourceRef, error)

returns the ref of the upstream for a given cluster

func EnvoyCacheResourcesListToFnvHash added in v1.6.3

func EnvoyCacheResourcesListToFnvHash(resources []envoycache.Resource) uint64

func EnvoyCacheResourcesListToHash added in v1.6.3

utility function to transform gloo matcher to envoy route matcher

func MakeRdsResources added in v1.0.0

func MakeRdsResources(routeConfigs []*envoy_config_route_v3.RouteConfiguration) envoycache.Resources

func NewAccessLogWithConfig added in v0.18.1

func NewHttpConnectionManager

func NewHttpConnectionManager(
	listener *v1.HttpListener,
	httpFilters []*envoyhttp.HttpFilter,
	rdsName string,

func ParseTypedConfig added in v1.5.0

func ParseTypedConfig(c typedConfigObject, config proto.Message) error

func UpstreamToClusterName

func UpstreamToClusterName(upstream *core.ResourceRef) string

returns the name of the cluster created for a given upstream

func ValidateRouteDestinations added in v0.18.0

func ValidateRouteDestinations(snap *v1.ApiSnapshot, action *v1.RouteAction) error

func ValidateTcpRouteDestinations added in v1.4.2

func ValidateVirtualHostDomains added in v1.2.5

func ValidateVirtualHostDomains(virtualHosts []*v1.VirtualHost, httpListenerReport *validationapi.HttpListenerReport)

returns an error if any of the virtualhost domains overlap Visible for testing
