Types

type ClusterConfig 

type ClusterConfig struct {

	// Types that are assignable to ClusterImplementationSpecifier:
	//
	//	*ClusterConfig_DnsCacheConfig
	//	*ClusterConfig_SubClustersConfig
	ClusterImplementationSpecifier isClusterConfig_ClusterImplementationSpecifier `protobuf_oneof:"cluster_implementation_specifier"`
	// If true allow the cluster configuration to disable the auto_sni and auto_san_validation options
	// in the :ref:`cluster's upstream_http_protocol_options
	// <envoy_v3_api_field_config.cluster.v3.Cluster.upstream_http_protocol_options>`
	AllowInsecureClusterOptions bool `` /* 147-byte string literal not displayed */
	// If true allow HTTP/2 and HTTP/3 connections to be reused for requests to different
	// origins than the connection was initially created for. This will only happen when the
	// resolved address for the new connection matches the peer address of the connection and
	// the TLS certificate is also valid for the new hostname. For example, if a connection
	// has previously been established to foo.example.com at IP 1.2.3.4 with a certificate
	// that is valid for “*.example.com“, then this connection could be used for requests to
	// bar.example.com if that also resolved to 1.2.3.4.
	//
	// .. note::
	//
	//	By design, this feature will maximize reuse of connections. This means that instead
	//	opening a new connection when an existing connection reaches the maximum number of
	//	concurrent streams, requests will instead be sent to the existing connection.
	//
	// .. note::
	//
	//	The coalesced connections might be to upstreams that would not be otherwise
	//	selected by Envoy. See the section `Connection Reuse in RFC 7540
	//	<https://datatracker.ietf.org/doc/html/rfc7540#section-9.1.1>`_
	AllowCoalescedConnections bool `` /* 139-byte string literal not displayed */
	// contains filtered or unexported fields

type ClusterConfig_DnsCacheConfig 

type ClusterConfig_DnsCacheConfig struct {

type ClusterConfig_SubClustersConfig 

type ClusterConfig_SubClustersConfig struct {
	// Configuration for sub clusters, when this configuration is enabled,
	// Envoy will create an independent sub cluster dynamically for each host:port.

	// i.e. health_checks, dns_resolvers and etc.
	// And the load_assignment will be set to the only one endpoint, host:port.
	//
	// Compared to the dns_cache_config, it has the following advantages:
	//
	//  1. sub clusters will be created with the STRICT_DNS DiscoveryType,
	//     so that Envoy will use all of the IPs resolved from the host.
	//
	// 2. each sub cluster is full featured cluster, with lb_policy and health check and etc enabled.
