If set, this is the Bootstrap configuration used for the managed Envoy Proxy fleet instead of the default Bootstrap configuration set by Envoy Gateway. Some fields within the Bootstrap that are required to communicate with the xDS Server (Envoy Gateway) and receive xDS resources from it are not configurable and will result in the `EnvoyProxy` resource being rejected. Backward compatibility across minor versions is not guaranteed.

Setting this field to true would merge all Gateway Listeners under the parent Gateway Class. This means that the port, protocol and hostname tuple must be unique for every listener. If a duplicate listener is detected, the newer listener (based on timestamp) will be rejected and its status will be updated with a “Accepted=False” condition.
`shutdown`	ShutdownConfig	false	Shutdown defines configuration for graceful envoy shutdown process.
`filterOrder`	FilterPosition array	false	FilterOrder defines the order of filters in the Envoy proxy’s HTTP filter chain. The FilterPosition in the list will be applied in the order they are defined.

All headers will be included in the check request to a gRPC authorization server. Only the following headers will be included in the check request to an HTTP authorization server: Host, Method, Path, Content-Length, and Authorization. And these headers will always be included to the check request to an HTTP authorization server by default, no matter whether they are specified in HeadersToExtAuth or not.
`failOpen`	boolean	false	FailOpen is a switch used to control the behavior when a response from the External Authorization service cannot be obtained. If FailOpen is set to true, the system allows the traffic to pass through. Otherwise, if it is set to false or not set (defaulting to false), the system blocks the traffic and returns a HTTP 5xx error, reflecting a fail-closed approach. This setting determines whether to prioritize accessibility over strict security in case of authorization service failure.
`recomputeRoute`	boolean	false	RecomputeRoute clears the route cache and recalculates the routing decision. This field must be enabled if the headers added or modified by the ExtAuth are used for route matching decisions. If the recomputation selects a new route, features targeting the new matched route will be applied.

Appears in:

XForwardedClientCert

Value	Description
`Subject`	XFCCCertDataSubject is the Subject field of the current client certificate.

XFCCForwardMode

Underlying type: string

XFCCForwardMode defines how XFCC header is handled by Envoy Proxy.

Appears in:

XForwardedClientCert

Value	Description
`Sanitize`	XFCCForwardModeSanitize removes the XFCC header from the request. This is the default mode.
`ForwardOnly`	XFCCForwardModeForwardOnly forwards the XFCC header in the request if the client connection is mTLS.
`AppendForward`	XFCCForwardModeAppendForward appends the client certificate information to the request’s XFCC header and forward it if the client connection is mTLS.
`SanitizeSet`	XFCCForwardModeSanitizeSet resets the XFCC header with the client certificate information and forward it if the client connection is mTLS. The existing certificate information in the XFCC header is removed.
`AlwaysForwardOnly`	XFCCForwardModeAlwaysForwardOnly always forwards the XFCC header in the request, regardless of whether the client connection is mTLS.

XForwardedClientCert

XForwardedClientCert configures how Envoy Proxy handle the x-forwarded-client-cert (XFCC) HTTP header.

Appears in:

HeaderSettings

Field	Type	Required	Description
`mode`	XFCCForwardMode	false	Mode defines how XFCC header is handled by Envoy Proxy. If not set, the default mode is `Sanitize`.
`certDetailsToAdd`	XFCCCertData array	false	CertDetailsToAdd specifies the fields in the client certificate to be forwarded in the XFCC header. Hash(the SHA 256 digest of the current client certificate) and By(the Subject Alternative Name) are always included if the client certificate is forwarded. This field is only applicable when the mode is set to `AppendForward` or `SanitizeSet` and the client connection is mTLS.

XForwardedForSettings

XForwardedForSettings provides configuration for using X-Forwarded-For headers for determining the client IP address. Refer to https://www.envoyproxy.io/docs/envoy/latest/configuration/http/http_conn_man/headers#x-forwarded-for for more details.

Appears in:

ClientIPDetectionSettings

Field	Type	Required	Description
`numTrustedHops`	integer	false	NumTrustedHops controls the number of additional ingress proxy hops from the right side of XFF HTTP headers to trust when determining the origin client’s IP address. Only one of NumTrustedHops and TrustedCIDRs must be set.

ZipkinTracingProvider

ZipkinTracingProvider defines the Zipkin tracing provider configuration.

Appears in:

TracingProvider

Field	Type	Required	Description
`enable128BitTraceId`	boolean	false	Enable128BitTraceID determines whether a 128bit trace id will be used when creating a new trace instance. If set to false, a 64bit trace id will be used.
`disableSharedSpanContext`	boolean	false	DisableSharedSpanContext determines whether the default Envoy behaviour of client and server spans sharing the same span context should be disabled.
