Functions

func CheckForDuplicateFilterChainMatches

func CheckForDuplicateFilterChainMatches(filterChains []*envoylistener.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 DataSourceFromString

func DataSourceFromString(str string) *envoycore.DataSource

func GlooMatcherToEnvoyMatcher

func GlooMatcherToEnvoyMatcher(params plugins.Params, matcher *matchers.Matcher) envoyroute.RouteMatch

utility function to transform gloo matcher to envoy route matcher

func MakeRdsResources

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

func NewAccessLogWithConfig

func NewAccessLogWithConfig(name string, config proto.Message) (envoyal.AccessLog, error)

func NewFilterWithTypedConfig

func NewFilterWithTypedConfig(name string, config proto.Message) (*envoylistener.Filter, error)

func NewHttpConnectionManager

func ParseTypedConfig

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

func ParseTypedGogoConfig

func ParseTypedGogoConfig(c gogoTypedConfigObject, 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

func ValidateVirtualHostDomains

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

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