Functions

func AnyToMessage

func AnyToMessage(a *pany.Any) (proto.Message, error)

func EnsureRouteAction(out *envoy_config_route_v3.Route) error

func EnvoyPathAsString

func EnvoyPathAsString(matcher *envoy_config_route_v3.RouteMatch) string

func FilterLogLevel

func FilterLogLevel(r io.ReadCloser, level LogLevel) strings.Builder

Filter JSON logs with level

func GetCommonTlsContextFromUpstreamOptions

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 GogoMessageToAnyGoProto

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

gogoprotos converted directly to goproto any can't be marshalled unless you wrap the contents of the gogoproto in a typed struct

func MessageToAny

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

func MustAnyToMessage

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

func MustGogoMessageToAnyGoProto

func MustGogoMessageToAnyGoProto(msg proto.Message) *pany.Any

gogoprotos converted directly to goproto any can't be marshalled unless you wrap the contents of the gogoproto in a typed struct

func MustMessageToAny

func MustMessageToAny(msg proto.Message) *pany.Any

func NewSslConfigTranslator

func NewSslConfigTranslator() *sslConfigTranslator

func PathAsString

func PathAsString(matcher *matchers.Matcher) string

func SanitizeForEnvoy

func SanitizeForEnvoy(ctx context.Context, resourceName, resourceTypeName string) string

func SortGatewayRoutesByPath

func SortGatewayRoutesByPath(routes []*gatewayv1.Route)

func SortRoutesByPath

func SortRoutesByPath(routes []*v1.Route)

Matchers sort according to the following rules: 1. exact path < regex path < prefix path 2. lexicographically greater path string < lexicographically smaller path string

Types

type CertSource

type CertSource interface {
	GetSecretRef() *core.ResourceRef
	GetSslFiles() *v1.SSLFiles
	GetSds() *v1.SDSConfig
	GetVerifySubjectAltName() []string
	GetParameters() *v1.SslParameters
	GetAlpnProtocols() []string
}

type LogLevel

type LogLevel int8

A Level is a logging priority. Higher levels are more important.

const (
	LogLevelInfo LogLevel = iota - 1
	LogLevelWarn
	LogLevelError
	LogLevelAll
)

func (LogLevel) String

func (l LogLevel) String() string

String returns a lower-case ASCII representation of the log level.

type SslConfigTranslator

type SslConfigTranslator interface {
	ResolveUpstreamSslConfig(secrets v1.SecretList, uc *v1.UpstreamSslConfig) (*envoyauth.UpstreamTlsContext, error)
	ResolveDownstreamSslConfig(secrets v1.SecretList, dc *v1.SslConfig) (*envoyauth.DownstreamTlsContext, error)
	ResolveCommonSslConfig(cs CertSource, secrets v1.SecretList, mustHaveCert bool) (*envoyauth.CommonTlsContext, error)
	ResolveSslParamsConfig(params *v1.SslParameters) (*envoyauth.TlsParameters, error)
}
