func GetCommonTlsContextFromUpstreamOptions added in v1.6.9 

func GetCommonTlsContextFromUpstreamOptions(options *v1.UpstreamOptions) (*envoyauth.CommonTlsContext, error)

We support global UpstreamOptions to define SslParameters for all upstreams If an upstream is configure with ssl, it will inherit the defaults here: https://github.com/solo-io/gloo/blob/15da82bdd65ab4bcedbc7fb803ea0bb5f7e926fc/projects/gloo/pkg/translator/clusters.go#L108 However, if an upstream is configured with one-way TLS, we must explicitly apply the defaults, since there is no ssl configuration on the upstream

func GetTcpHostReportsFromListenerReport added in v1.14.12 

func GetTcpHostReportsFromListenerReport(listenerReport *validation.ListenerReport) []*validation.TcpHostReport

Given any supported listener type, returns the TcpHost report objects that are used for error/warning reporting

func GetTranslatorSelectorExpression added in v1.17.0 

func GetTranslatorSelectorExpression(translators ...string) string

func GetTranslatorValue added in v1.17.0 

func GetTranslatorValue(meta *core.Metadata) string

func GetVhostReportsFromListenerReport added in v1.9.25 

func GetVhostReportsFromListenerReport(listenerReport *validation.ListenerReport) []*validation.VirtualHostReport

func GetVirtualHostsForListener added in v1.9.25 

func GetVirtualHostsForListener(listener *v1.Listener) []*v1.VirtualHost

func MatchedRouteConfigName added in v1.9.25 

func MatchedRouteConfigName(listener *v1.Listener, matcher *v1.Matcher) string

MatchedRouteConfigName returns a unique RouteConfiguration name This name is commonly used for 2 purposes:

  1. to associate the RouteConfigurationName between RDS and the HttpConnectionManager NetworkFilter
  2. To provide a consistent key function for a map of ListenerReports

func MergeResourceLists added in v1.9.1 

func MergeResourceLists(existingResources sk_resources.ResourceList, modifiedResources sk_resources.ResourceList) sk_resources.ResourceList

Merges the modified resources into the existing resources, overwriting any existing values, and returns the new list

func MessageToAny added in v1.5.0 

func MessageToAny(msg proto.Message) (*pany.Any, error)

MessageToAny takes any given proto message msg and returns the marshalled bytes of the proto, and a url to the type definition for the proto in the form of a *pany.Any, errors if nil or if the proto type doesnt exist or if there is a marshalling error

func MustAnyToMessage deprecated added in v1.5.0 

func MustAnyToMessage(a *pany.Any) proto.Message

Deprecated: Use AnyToMessage

func NewSslConfigTranslator

func RouteConfigName added in v1.9.25 

func RouteConfigName(listener *v1.Listener) string

RouteConfigName cannot always be relied on to get the route config name for any listener because the pattern is different for hybrid listeners (see MatchedRouteConfigName below)

func ShallowMergeRouteOptions added in v1.17.0 

func ShallowMergeRouteOptions(dst, src *v1.RouteOptions) (*v1.RouteOptions, bool)

ShallowMergeRouteOptions merges the top-level fields of src into dst. The fields in dst that have non-zero values will not be overwritten. It performs a shallow merge of top-level fields only. It returns a boolean indicating whether any fields in src overwrote dst.

func ShallowMergeVirtualHostOptions added in v1.17.4 

func ShallowMergeVirtualHostOptions(dst, src *v1.VirtualHostOptions) (*v1.VirtualHostOptions, bool)

ShallowMergeVirtualHostOptions merges the top-level fields of src into dst. The fields in dst that have non-zero values will not be overwritten. It performs a shallow merge of top-level fields only. It returns a boolean indicating whether any fields in src overwrote dst.
