R.B. Boyer	1eef096dfe	xds: version sniff envoy and switch regular expressions from 'regex' to 'safe_regex' on newer envoy versions (#8222) ... - cut down on extra node metadata transmission - split the golden file generation to compare all envoy version	4 years ago
Chris Piraino	735337b170	Append port number to ingress host domain (#8190) ... A port can be sent in the Host header as defined in the HTTP RFC, so we take any hosts that we want to match traffic to and also add another host with the listener port added. Also fix an issue with envoy integration tests not running the case-ingress-gateway-tls test.	4 years ago

Freddy	166a8b2a58	Only pass one hostname via EDS and prefer healthy ones (#8084) ... Co-authored-by: Matt Keeler <mkeeler@users.noreply.github.com> Currently when passing hostname clusters to Envoy, we set each service instance registered with Consul as an LbEndpoint for the cluster. However, Envoy can only handle one per cluster: [2020-06-04 18:32:34.094][1][warning][config] [source/common/config/grpc_subscription_impl.cc:87] gRPC config for type.googleapis.com/envoy.api.v2.Cluster rejected: Error adding/updating cluster(s) dc2.internal.ddd90499-9b47-91c5-4616-c0cbf0fc358a.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint, server.dc2.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint Envoy is currently handling this gracefully by only picking one of the endpoints. However, we should avoid passing multiple to avoid these warning logs. This PR: * Ensures we only pass one endpoint, which is tied to one service instance. * We prefer sending an endpoint which is marked as Healthy by Consul. * If no endpoints are healthy we emit a warning and skip the cluster. * If multiple unique hostnames are spread across service instances we emit a warning and let the user know which will be resolved.	5 years ago

Daniel Nephin	c66c533d73	Merge pull request #7964 from hashicorp/dnephin/remove-patch-slice-of-maps-forward-compat ... config: Use HookWeakDecodeFromSlice in place of PatchSliceOfMaps	5 years ago
Daniel Nephin	75cbbe2702	config: add HookWeakDecodeFromSlice ... Currently opaque config blocks (config entries, and CA provider config) are modified by PatchSliceOfMaps, making it impossible for these opaque config sections to contain slices of maps. In order to fix this problem, any lazy-decoding of these blocks needs to support weak decoding of []map[string]interface{} to a struct type before PatchSliceOfMaps is replaces. This is necessary because these config blobs are persisted, and during an upgrade an older version of Consul could read one of the new configuration values, which would cause an error. To support the upgrade path, this commit first introduces the new hooks for weak decoding of []map[string]interface{} and uses them only in the lazy-decode paths. That way, in a future release, new style configuration will be supported by the older version of Consul. This decode hook has a number of advantages: 1. It no longer panics. It allows mapstructure to report the error 2. It no longer requires the user to declare which fields are slices of structs. It can deduce that information from the 'to' value. 3. It will make it possible to preserve opaque configuration, allowing for structured opaque config.	5 years ago
Chris Piraino	1a853fc954	Always require Host header values for http services (#7990) ... Previously, we did not require the 'service-name.*' host header value when on a single http service was exposed. However, this allows a user to get into a situation where, if they add another service to the listener, suddenly the previous service's traffic might not be routed correctly. Thus, we always require the Host header, even if there is only 1 service. Also, we add the make the default domain matching more restrictive by matching "service-name.ingress.*" by default. This lines up better with the namespace case and more accurately matches the Consul DNS value we expect people to use in this case.	5 years ago
Freddy	9ed325ba8b	Enable gateways to resolve hostnames to IPv4 addresses (#7999) ... The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option. If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS. Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.	5 years ago

Chris Piraino	f55e20a2f7	Allow ingress gateways to send empty clusters, routes, and listeners (#7795) ... This is useful when updating an config entry with no services, and the expected behavior is that envoy closes all listeners and clusters. We also allow empty routes because ingress gateways name route configurations based on the port of the listener, so it is important we remove any stale routes. Then, if a new listener with an old port is added, we will not have to deal with stale routes hanging around routing to the wrong place. Endpoints are associated with clusters, and thus by deleting the clusters we don't have to care about sending empty endpoint responses.	5 years ago

Kyle Havlovitz	247f9eaf13	Allow ingress gateways to route traffic based on Host header ... This commit adds the necessary changes to allow an ingress gateway to route traffic from a single defined port to multiple different upstream services in the Consul mesh. To do this, we now require all HTTP requests coming into the ingress gateway to specify a Host header that matches "<service-name>.*" in order to correctly route traffic to the correct service. - Differentiate multiple listener's route names by port - Adds a case in xds for allowing default discovery chains to create a route configuration when on an ingress gateway. This allows default services to easily use host header routing - ingress-gateways have a single route config for each listener that utilizes domain matching to route to different services.	5 years ago

Andy Lindeman	c1cb18c648	proxycfg: support path exposed with non-HTTP2 protocol (#7510) ... If a proxied service is a gRPC or HTTP2 service, but a path is exposed using the HTTP1 or TCP protocol, Envoy should not be configured with `http2ProtocolOptions` for the cluster backing the path. A situation where this comes up is a gRPC service whose healthcheck or metrics route (e.g. for Prometheus) is an HTTP1 service running on a different port. Previously, if these were exposed either using `Expose: { Checks: true }` or `Expose: { Paths: ... }`, Envoy would still be configured to communicate with the path over HTTP2, which would not work properly.	5 years ago
