ListenerOptions

Optional, feature-specific configuration that lives on gateways. Each ListenerOption object contains configuration for a specific feature. Note to developers: new Listener plugins must be added to this struct to be usable by Gloo. (plugins currently need to be compiled into Gloo)

"accessLoggingService": .als.options.gloo.solo.io.AccessLoggingService
"extensions": .gloo.solo.io.Extensions
"perConnectionBufferLimitBytes": .google.protobuf.UInt32Value
"socketOptions": []solo.io.envoy.api.v2.core.SocketOption
"proxyProtocol": .proxy_protocol.options.gloo.solo.io.ProxyProtocol
"connectionBalanceConfig": .gloo.solo.io.ConnectionBalanceConfig
"listenerAccessLoggingService": .als.options.gloo.solo.io.AccessLoggingService
Field Type Description
accessLoggingService .als.options.gloo.solo.io.AccessLoggingService Configuration for access logging in a filter like the HttpConnectionManager.
extensions .gloo.solo.io.Extensions Extensions will be passed along from Listeners, Gateways, VirtualServices, Routes, and Route tables to the underlying Proxy, making them useful for controllers, validation tools, etc. which interact with kubernetes yaml. Some sample use cases: * controllers, deployment pipelines, helm charts, etc. which wish to use extensions as a kind of opaque metadata. * In the future, Gloo may support gRPC-based plugins which communicate with the Gloo translator out-of-process. Opaque Extensions enables development of out-of-process plugins without requiring recompiling & redeploying Gloo’s API.
perConnectionBufferLimitBytes .google.protobuf.UInt32Value Soft limit on size of the listener’s new connection read and write buffers. If unspecified, defaults to 1MiB For more info, check out the Envoy docs.
socketOptions []solo.io.envoy.api.v2.core.SocketOption Additional socket options that may not be present in Envoy source code or precompiled binaries.
proxyProtocol .proxy_protocol.options.gloo.solo.io.ProxyProtocol Enable ProxyProtocol support for this listener.
connectionBalanceConfig .gloo.solo.io.ConnectionBalanceConfig Configuration for listener connection balancing.
listenerAccessLoggingService .als.options.gloo.solo.io.AccessLoggingService If enabled this sets up an early access logging service for the listener. Added initially to support listener level logging for HTTP listeners. For more info see https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/listener/v3/listener.proto#envoy-v3-api-field-config-listener-v3-listener-access-log.

ConnectionBalanceConfig

Configuration for listener connection balancing.

"exactBalance": .gloo.solo.io.ConnectionBalanceConfig.ExactBalance
Field Type Description
exactBalance .gloo.solo.io.ConnectionBalanceConfig.ExactBalance

ExactBalance

A connection balancer implementation that does exact balancing. This means that a lock is held during balancing so that connection counts are nearly exactly balanced between worker threads. This is “nearly” exact in the sense that a connection might close in parallel thus making the counts incorrect, but this should be rectified on the next accept. This balancer sacrifices accept throughput for accuracy and should be used when there are a small number of connections that rarely cycle (e.g., service mesh gRPC egress).
Field Type Description

RouteConfigurationOptions

"maxDirectResponseBodySizeBytes": .google.protobuf.UInt32Value
"mostSpecificHeaderMutationsWins": .google.protobuf.BoolValue
Field Type Description
maxDirectResponseBodySizeBytes .google.protobuf.UInt32Value The maximum bytes of the response direct response body size. If not specified the default is 4096. Please refer to the Envoy documentation for more details about the max_direct_response_body_size_bytes attribute.
mostSpecificHeaderMutationsWins .google.protobuf.BoolValue By default, headers that should be added/removed are evaluated from most to least specific. To allow setting overrides at the route or virtual host level, this order can be reversed by setting this option to true. Refer to the Envoy documentation for more details.

extProc .extproc.options.gloo.solo.io.Settings Enterprise-only: External Processing filter settings for the listener. This can be used to override the defaults from the global settings (via shallow merge). Some of the settings on the listener can be overridden by child VirtualHostOptions or RouteOptions. Only one of extProc or disableExtProc can be set.
gzip .solo.io.envoy.config.filter.http.gzip.v2.Gzip Gzip is an HTTP option which enables Gloo to compress data returned from an upstream service upon client request. Compression is useful in situations where large payloads need to be transmitted without compromising the response time. Example: gzip: contentType: - "application/json" compressionLevel: BEST.
proxyLatency .envoy.config.filter.http.proxylatency.v2.ProxyLatency Enterprise-only: Proxy latency.
buffer .solo.io.envoy.extensions.filters.http.buffer.v3.Buffer Buffer can be used to set the maximum request size that the filter will buffer before the connection manager will stop buffering and return a 413 response.
csrf .solo.io.envoy.extensions.filters.http.csrf.v3.CsrfPolicy Csrf can be used to set percent of requests for which the CSRF filter is enabled, enable shadow-only mode where policies will be evaluated and tracked, but not enforced and add additional source origins that will be allowed in addition to the destination origin. For more, see https://www.envoyproxy.io/docs/envoy/latest/api-v2/config/filter/http/csrf/v2/csrf.proto.
grpcJsonTranscoder .grpc_json.options.gloo.solo.io.GrpcJsonTranscoder Exposed envoy config for the gRPC to JSON transcoding filter, envoy.filters.http.grpc_json_transcoder. For more, see https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/http/grpc_json_transcoder/v3/transcoder.proto.
sanitizeClusterHeader .google.protobuf.BoolValue Enterprise-only: If using the HTTP header specified by cluster_header to direct traffic to a cluster, this option will sanitize that header from downstream traffic. Defaults to false.
leftmostXffAddress .google.protobuf.BoolValue Enterprise-only: Setting this value to true will grab the leftmost IP address from the x-forwarded-for header and set it as the downstream address. It is worth noting that the x-forwarded-for header can be tampered with by clients and should therefore be sanitized by any preceding proxies / load balancers if this option is to be used.
dynamicForwardProxy .dfp.options.gloo.solo.io.FilterConfig
connectionLimit .connection_limit.options.gloo.solo.io.ConnectionLimit ConnectionLimit can be used to limit the number of active connections per gateway. Useful for resource protection as well as DoS prevention.
networkLocalRatelimit .local_ratelimit.options.gloo.solo.io.TokenBucket NetworkLocalRatelimit can be used to rate limit the connections per gateway at the L4 layer and works pre-auth. It uses envoy’s own local rate limit filter to do so, without the need for an external rate limit server to be set up.
httpLocalRatelimit .local_ratelimit.options.gloo.solo.io.Settings HttpLocalRatelimit can be used to rate limit the number of requests per gateway and works pre-auth. Unlike the NetworkLocalRatelimit, this works as part of the HCM (ie: L7 layer). All virtual host and routes that are part of this gateway will share this rate limit unless explicity configured with another limit. It uses envoy’s own local rate limit filter to do so, without the need for an external rate limit server to be set up.
router .gloo.solo.io.Router Router is an extension of the envoy http filters Maps to https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/http/router/v3/router.proto.

cors .cors.options.gloo.solo.io.CorsPolicy Defines a CORS policy for the virtual host. If a CORS policy is also defined on the route matched by the request, the route policy overrides the virtual host policy for any configured field unless CorsPolicyMergeSettings are specified that define an alternate behavior.
transformations .transformation.options.gloo.solo.io.Transformations Transformations to apply. Note: this field is superseded by staged_transformations. If staged_transformations.regular is set, this field will be ignored.
ratelimitBasic .ratelimit.options.gloo.solo.io.IngressRateLimit Enterprise-only: Config for GlooE rate-limiting using simplified (gloo-specific) API.
ratelimitEarly .ratelimit.options.gloo.solo.io.RateLimitVhostExtension Enterprise-only: Partial config for GlooE rate-limiting based on Envoy’s rate-limit service; supports Envoy’s rate-limit service API. (reference here: https://github.com/lyft/ratelimit#configuration) Configure rate-limit actions here, which define how request characteristics get translated into descriptors used by the rate-limit service for rate-limiting. Configure rate-limit descriptors and their associated limits on the Gloo settings. Only one of ratelimit_early or rate_limit_early_configs can be set. Only one of ratelimitEarly or rateLimitEarlyConfigs can be set.

jwt .jwt.options.gloo.solo.io.VhostExtension Enterprise-only: Config for reading and verifying JWTs. Copy verifiable information from JWTs into other headers to make routing decisions or combine with RBAC for fine-grained access control. This has been deprecated in favor of staged jwt. The same configuration can be achieved through staged jwt using AfterExtAuth. Only one of jwt or jwtStaged can be set.
jwtStaged .jwt.options.gloo.solo.io.JwtStagedVhostExtension Enterprise-only: Config for reading and verifying JWTs. Copy verifiable information from JWTs into other headers to make routing decisions or combine with RBAC for fine-grained access control. JWT configuration has stages “BeforeExtAuth” and “AfterExtAuth”. BeforeExtAuth JWT validation runs before the external authentication service. This is useful when JWT is used in conjunction with other auth mechanisms specified in the boolean expression Extauth API. AfterExtAuth validation runs after external authentication service, which is useful for verifying JWTs obtained during extauth (e.g. oauth/oidc). Only one of jwtStaged or jwt can be set.

Note: If you have not set a global config (at the gateway level), this override will not do anything by itself.
csrf .solo.io.envoy.extensions.filters.http.csrf.v3.CsrfPolicy Csrf can be used to set percent of requests for which the CSRF filter is enabled, enable shadow-only mode where policies will be evaluated and tracked, but not enforced and add additional source origins that will be allowed in addition to the destination origin. For more, see https://www.envoyproxy.io/docs/envoy/latest/api-v2/config/filter/http/csrf/v2/csrf.proto.
includeRequestAttemptCount .google.protobuf.BoolValue IncludeRequestAttemptCount decides whether the x-envoy-attempt-count header should be included in the upstream request. Setting this option will cause it to override any existing header value, so in the case of two Envoys on the request path with this option enabled, the upstream will see the attempt count as perceived by the second Envoy. Defaults to false.
includeAttemptCountInResponse .google.protobuf.BoolValue IncludeAttemptCountInResponse decides whether the x-envoy-attempt-count header should be included in the downstream response. Setting this option will cause the router to override any existing header value, so in the case of two Envoys on the request path with this option enabled, the downstream will see the attempt count as perceived by the Envoy closest upstream from itself. Defaults to false.
stagedTransformations .transformation.options.gloo.solo.io.TransformationStages Early transformations stage. These transformations run before most other options are processed. If the regular field is set in here, the transformations field is ignored.
extProc .extproc.options.gloo.solo.io.RouteSettings Enterprise-only: External Processing filter settings for the virtual host. This can be used to override certain HttpListenerOptions settings, and can be overridden by RouteOptions settings.

Configure rate-limit descriptors and their associated limits on the Gloo settings. Only one of ratelimit or rate_limit_configs can be set. Only one of ratelimit or rateLimitConfigs can be set.
rateLimitConfigs .ratelimit.options.gloo.solo.io.RateLimitConfigRefs References to RateLimitConfig resources. This is used to configure the GlooE rate limit server. Only one of ratelimit or rate_limit_configs can be set. Only one of rateLimitConfigs or ratelimit can be set.
ratelimitRegular .ratelimit.options.gloo.solo.io.RateLimitRouteExtension Enterprise-only: Partial config for GlooE rate-limiting based on Envoy’s rate-limit service; supports Envoy’s rate-limit service API. (reference here: https://github.com/lyft/ratelimit#configuration) Configure rate-limit actions here, which define how request characteristics get translated into descriptors used by the rate-limit service for rate-limiting. Configure rate-limit descriptors and their associated limits on the Gloo settings. Only one of ratelimit_early or rate_limit_early_configs can be set. Only one of ratelimitRegular or rateLimitRegularConfigs can be set.
rateLimitRegularConfigs .ratelimit.options.gloo.solo.io.RateLimitConfigRefs References to RateLimitConfig resources. This is used to configure the GlooE rate limit server. Only one of ratelimit_early or rate_limit_early_configs can be set. Only one of rateLimitRegularConfigs or ratelimitRegular can be set.
waf .waf.options.gloo.solo.io.Settings Enterprise-only: Config for Web Application Firewall (WAF), supporting the popular ModSecurity 3.0 ruleset.
jwt .jwt.options.gloo.solo.io.RouteExtension Enterprise-only: Config for reading and verifying JWTs. Copy verifiable information from JWTs into other headers to make routing decisions or combine with RBAC for fine-grained access control. This has been deprecated in favor of staged jwt. The same configuration can be achieved through staged jwt using AfterExtAuth. Only one of jwt, jwtStaged, or jwtProvidersStaged can be set.
jwtStaged .jwt.options.gloo.solo.io.JwtStagedRouteExtension Enterprise-only: Config for reading and verifying JWTs. Copy verifiable information from JWTs into other headers to make routing decisions or combine with RBAC for fine-grained access control. JWT configuration has stages “BeforeExtAuth” and “AfterExtAuth”. BeforeExtAuth JWT validation runs before the external authentication service. This is useful when JWT is used in conjunction with other auth mechanisms specified in the boolean expression Extauth API. AfterExtAuth validation runs after external authentication service, which is useful for verifying JWTs obtained during extauth (e.g. oauth/oidc). Only one of jwtStaged, jwt, or jwtProvidersStaged can be set.
jwtProvidersStaged .jwt.options.gloo.solo.io.JwtStagedRouteProvidersExtension Enterprise-only: Config for reading and verifying JWTs. Copy verifiable information from JWTs into other headers to make routing decisions or combine with RBAC for fine-grained access control. JWT configuration has stages “BeforeExtAuth” and “AfterExtAuth”. BeforeExtAuth JWT validation runs before the external authentication service. This is useful when JWT is used in conjunction with other auth mechanisms specified in the boolean expression Extauth API. AfterExtAuth validation runs after external authentication service, which is useful for verifying JWTs obtained during extauth (e.g. oauth/oidc). Only one of jwtProvidersStaged, jwt, or jwtStaged can be set.
rbac .rbac.options.gloo.solo.io.ExtensionSettings Enterprise-only: Config for RBAC (currently only supports RBAC based on JWT claims).
extauth .enterprise.gloo.solo.io.ExtAuthExtension Enterprise-only: Authentication configuration.
dlp .dlp.options.gloo.solo.io.Config Enterprise-only: Config for data loss prevention.
bufferPerRoute .solo.io.envoy.extensions.filters.http.buffer.v3.BufferPerRoute BufferPerRoute can be used to set the maximum request size that the filter will buffer before the connection manager will stop buffering and return a 413 response. Note: If you have not set a global config (at the gateway level), this override will not do anything by itself.
csrf .solo.io.envoy.extensions.filters.http.csrf.v3.CsrfPolicy Csrf can be used to set percent of requests for which the CSRF filter is enabled, enable shadow-only mode where policies will be evaluated and tracked, but not enforced and add additional source origins that will be allowed in addition to the destination origin. For more, see https://www.envoyproxy.io/docs/envoy/latest/api-v2/config/filter/http/csrf/v2/csrf.proto.
stagedTransformations .transformation.options.gloo.solo.io.TransformationStages Early transformations stage. These transformations run before most other options are processed. If the regular field is set in here, the transformations field is ignored.
envoyMetadata map<string, .google.protobuf.Struct> This field can be used to provide additional information about the route. This metadata can be consumed by the Envoy filters that process requests that match the route. For more info about metadata, see here. The value of this field will be propagated to the metadata attribute of the corresponding Envoy route. Please refer to the Envoy documentation for more details about the metadata attribute.
regexRewrite .solo.io.envoy.type.matcher.v3.RegexMatchAndSubstitute For requests matched on this route, rewrite the HTTP request path according to the provided regex pattern before forwarding upstream Please refer to the Envoy documentation for more details about the regex_rewrite attribute.
maxStreamDuration .gloo.solo.io.RouteOptions.MaxStreamDuration Settings for maximum durations and timeouts for streams on the route. Please refer to the Envoy documentation.
idleTimeout .google.protobuf.Duration Specifies the idle timeout for the route. If not specified, there is no per-route idle timeout, although the Gateway’s httpConnectionManagerSettings wide stream_idle_timeout will still apply. A value of 0 will completely disable the route’s idle timeout, even if a connection manager stream idle timeout is configured. Please refer to the Envoy documentation.
extProc .extproc.options.gloo.solo.io.RouteSettings Enterprise-only: External Processing filter settings for the route. This can be used to override certain HttpListenerOptions or VirtualHostOptions settings.
ai .ai.options.gloo.solo.io.RouteSettings Enterprise-only: Settings to configure ai settings for a route. These settings will only apply if the backend is an ai Upstream.

MaxStreamDuration

This is a 1:1 translation to the Envoy API described here

"maxStreamDuration": .google.protobuf.Duration
"grpcTimeoutHeaderMax": .google.protobuf.Duration
"grpcTimeoutHeaderOffset": .google.protobuf.Duration
Field Type Description
maxStreamDuration .google.protobuf.Duration Specifies the maximum duration allowed for streams on the route. If not specified, the value from the max_stream_duration field in HttpConnectionManager.common_http_protocol_options is used. If this field is set explicitly to zero, any HttpConnectionManager max_stream_duration timeout will be disabled for this route.
grpcTimeoutHeaderMax .google.protobuf.Duration If present, and the request contains a grpc-timeout header, use that value as the max_stream_duration, but limit the applied timeout to the maximum value specified here. If set to 0, the grpc-timeout header is used without modification.
grpcTimeoutHeaderOffset .google.protobuf.Duration If present, Envoy will adjust the timeout provided by the grpc-timeout header by subtracting the provided duration from the header. This is useful for allowing Envoy to set its global timeout to be less than that of the deadline imposed by the calling client, which makes it more likely that Envoy will handle the timeout instead of having the call canceled by the client. If, after applying the offset, the resulting timeout is zero or negative, the stream will timeout immediately.

DestinationSpec

Configuration for Destinations that are tied to the UpstreamSpec or ServiceSpec on that destination

"aws": .aws.options.gloo.solo.io.DestinationSpec
"azure": .azure.options.gloo.solo.io.DestinationSpec
"rest": .rest.options.gloo.solo.io.DestinationSpec
"grpc": .grpc.options.gloo.solo.io.DestinationSpec
Field Type Description
aws .aws.options.gloo.solo.io.DestinationSpec Only one of aws, azure, rest, or grpc can be set.
azure .azure.options.gloo.solo.io.DestinationSpec Only one of azure, aws, rest, or grpc can be set.
rest .rest.options.gloo.solo.io.DestinationSpec Only one of rest, aws, azure, or grpc can be set.
grpc .grpc.options.gloo.solo.io.DestinationSpec Only one of grpc, aws, azure, or rest can be set.

WeightedDestinationOptions

Optional, feature-specific configuration that is applied when a specific weighted destination is selected for routing.

"headerManipulation": .headers.options.gloo.solo.io.HeaderManipulation
"transformations": .transformation.options.gloo.solo.io.Transformations
"extensions": .gloo.solo.io.Extensions
"extauth": .enterprise.gloo.solo.io.ExtAuthExtension
"bufferPerRoute": .solo.io.envoy.extensions.filters.http.buffer.v3.BufferPerRoute
"csrf": .solo.io.envoy.extensions.filters.http.csrf.v3.CsrfPolicy
"stagedTransformations": .transformation.options.gloo.solo.io.TransformationStages
Field Type Description
headerManipulation .headers.options.gloo.solo.io.HeaderManipulation Append/Remove headers on Requests or Responses to/from this Weighted Destination.
transformations .transformation.options.gloo.solo.io.Transformations Transformations to apply. Note: this field is superseded by staged_transformations. If staged_transformations.regular is set, this field will be ignored.
extensions .gloo.solo.io.Extensions Extensions will be passed along from Listeners, Gateways, VirtualServices, Routes, and Route tables to the underlying Proxy, making them useful for controllers, validation tools, etc. which interact with kubernetes yaml. Some sample use cases: * controllers, deployment pipelines, helm charts, etc. which wish to use extensions as a kind of opaque metadata. * In the future, Gloo may support gRPC-based plugins which communicate with the Gloo translator out-of-process. Opaque Extensions enables development of out-of-process plugins without requiring recompiling & redeploying Gloo’s API.
extauth .enterprise.gloo.solo.io.ExtAuthExtension Enterprise-only: Authentication configuration.
bufferPerRoute .solo.io.envoy.extensions.filters.http.buffer.v3.BufferPerRoute BufferPerRoute can be used to set the maximum request size that the filter will buffer before the connection manager will stop buffering and return a 413 response. Note: If you have not set a global config (at the gateway level), this override will not do anything by itself.
csrf .solo.io.envoy.extensions.filters.http.csrf.v3.CsrfPolicy Csrf can be used to set percent of requests for which the CSRF filter is enabled, enable shadow-only mode where policies will be evaluated and tracked, but not enforced and add additional source origins that will be allowed in addition to the destination origin. For more, see https://www.envoyproxy.io/docs/envoy/latest/api-v2/config/filter/http/csrf/v2/csrf.proto.
stagedTransformations .transformation.options.gloo.solo.io.TransformationStages Early transformations stage. These transformations run before most other options are processed. If the regular field is set in here, the transformations field is ignored.
