Types

type DnsCacheConfig

type DnsCacheConfig struct {
	// The name of the cache. Multiple named caches allow independent dynamic forward proxy
	// configurations to operate within a single Envoy process using different configurations. All
	// configurations with the same name *must* otherwise have the same settings when referenced
	// from different configuration components. Configuration will fail to load if this is not
	// the case.
	Name string `protobuf:"bytes,1,opt,name=name,proto3" json:"name,omitempty"`
	// The DNS lookup family to use during resolution.
	//
	// [#comment:TODO(mattklein123): Figure out how to support IPv4/IPv6 "happy eyeballs" mode. The
	// way this might work is a new lookup family which returns both IPv4 and IPv6 addresses, and
	// then configures a host to have a primary and fall back address. With this, we could very
	// likely build a "happy eyeballs" connection pool which would race the primary / fall back
	// address and return the one that wins. This same method could potentially also be used for
	// QUIC to TCP fall back.]
	DnsLookupFamily v2.Cluster_DnsLookupFamily `` /* 151-byte string literal not displayed */
	// The DNS refresh rate for currently cached DNS hosts. If not specified defaults to 60s.
	//
	// .. note:
	//
	//  The returned DNS TTL is not currently used to alter the refresh rate. This feature will be
	//  added in a future change.
	DnsRefreshRate *types.Duration `protobuf:"bytes,3,opt,name=dns_refresh_rate,json=dnsRefreshRate,proto3" json:"dns_refresh_rate,omitempty"`
	// The TTL for hosts that are unused. Hosts that have not been used in the configured time
	// interval will be purged. If not specified defaults to 5m.
	//
	// .. note:
	//
	//   The TTL is only checked at the time of DNS refresh, as specified by *dns_refresh_rate*. This
	//   means that if the configured TTL is shorter than the refresh rate the host may not be removed
	//   immediately.
	//
	//  .. note:
	//
	//   The TTL has no relation to DNS TTL and is only used to control Envoy's resource usage.
	HostTtl *types.Duration `protobuf:"bytes,4,opt,name=host_ttl,json=hostTtl,proto3" json:"host_ttl,omitempty"`
	// The maximum number of hosts that the cache will hold. If not specified defaults to 1024.
	//
	// .. note:
	//
	//   The implementation is approximate and enforced independently on each worker thread, thus
	//   it is possible for the maximum hosts in the cache to go slightly above the configured
	//   value depending on timing. This is similar to how other circuit breakers work.
