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
Daniel Nephin	0a75d32e3e	ci: fix log capture for envoy integration tests The previous change, which moved test running to Go, appears to have broken log capturing. I am not entirely sure why, but the run_tests function seems to exit on the first error. This change moves test teardown and log capturing out of run_test, and has the go test runner call them when necessary.	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

R.B. Boyer	6adad71125	wan federation via mesh gateways (#6884 ) This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch: There are several distinct chunks of code that are affected: * new flags and config options for the server * retry join WAN is slightly different * retry join code is shared to discover primary mesh gateways from secondary datacenters * because retry join logic runs in the agent and the results of that operation for primary mesh gateways are needed in the server there are some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur at multiple layers of abstraction just to pass the data down to the right layer. * new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers * the function signature for RPC dialing picked up a new required field (the node name of the destination) * several new RPCs for manipulating a FederationState object: `FederationState:{Apply,Get,List,ListMeshGateways}` * 3 read-only internal APIs for debugging use to invoke those RPCs from curl * raft and fsm changes to persist these FederationStates * replication for FederationStates as they are canonically stored in the Primary and replicated to the Secondaries. * a special derivative of anti-entropy that runs in secondaries to snapshot their local mesh gateway `CheckServiceNodes` and sync them into their upstream FederationState in the primary (this works in conjunction with the replication to distribute addresses for all mesh gateways in all DCs to all other DCs) * a "gateway locator" convenience object to make use of this data to choose the addresses of gateways to use for any given RPC or gossip operation to a remote DC. This gets data from the "retry join" logic in the agent and also directly calls into the FSM. * RPC (`:8300`) on the server sniffs the first byte of a new connection to determine if it's actually doing native TLS. If so it checks the ALPN header for protocol determination (just like how the existing system uses the type-byte marker). * 2 new kinds of protocols are exclusively decoded via this native TLS mechanism: one for ferrying "packet" operations (udp-like) from the gossip layer and one for "stream" operations (tcp-like). The packet operations re-use sockets (using length-prefixing) to cut down on TLS re-negotiation overhead. * the server instances specially wrap the `memberlist.NetTransport` when running with gateway federation enabled (in a `wanfed.Transport`). The general gist is that if it tries to dial a node in the SAME datacenter (deduced by looking at the suffix of the node name) there is no change. If dialing a DIFFERENT datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh gateways to eventually end up in a server's :8300 port. * a new flag when launching a mesh gateway via `consul connect envoy` to indicate that the servers are to be exposed. This sets a special service meta when registering the gateway into the catalog. * `proxycfg/xds` notice this metadata blob to activate additional watches for the FederationState objects as well as the location of all of the consul servers in that datacenter. * `xds:` if the extra metadata is in place additional clusters are defined in a DC to bulk sink all traffic to another DC's gateways. For the current datacenter we listen on a wildcard name (`server.<dc>.consul`) that load balances all servers as well as one mini-cluster per node (`<node>.server.<dc>.consul`) * the `consul tls cert create` command got a new flag (`-node`) to help create an additional SAN in certs that can be used with this flavor of federation.	5 years ago

R.B. Boyer	8dcba472a2	xds: tcp services using the discovery chain should not assume RDS during LDS (#6623 ) Previously the logic for configuring RDS during LDS for L7 upstreams was overapplied to TCP proxies resulting in a cluster name of <emptystring> being used incorrectly. Fixes #6621	5 years ago
Freddy	fdd10dd8b8	Expose HTTP-based paths through Connect proxy (#6446 ) Fixes: #5396 This PR adds a proxy configuration stanza called expose. These flags register listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only listening on the loopback interface, while still accepting traffic from non Connect-enabled services. Under expose there is a boolean checks flag that would automatically expose all registered HTTP and gRPC check paths. This stanza also accepts a paths list to expose individual paths. The primary use case for this functionality would be to expose paths for third parties like Prometheus or the kubelet. Listeners for requests to exposed paths are be configured dynamically at run time. Any time a proxy, or check can be registered, a listener can also be created. In this initial implementation requests to these paths are not authenticated/encrypted.	5 years ago

R.B. Boyer	72207256b9	xds: improve how envoy metrics are emitted (#6312 ) Since generated envoy clusters all are named using (mostly) SNI syntax we can have envoy read the various fields out of that structure and emit it as stats labels to the various telemetry backends. I changed the delimiter for the 'customization hash' from ':' to '~' because ':' is always reencoded by envoy as '_' when generating metrics keys.	5 years ago
R.B. Boyer	8e22d80e35	connect: fix failover through a mesh gateway to a remote datacenter (#6259 ) Failover is pushed entirely down to the data plane by creating envoy clusters and putting each successive destination in a different load assignment priority band. For example this shows that normally requests go to 1.2.3.4:8080 but when that fails they go to 6.7.8.9:8080: - name: foo load_assignment: cluster_name: foo policy: overprovisioning_factor: 100000 endpoints: - priority: 0 lb_endpoints: - endpoint: address: socket_address: address: 1.2.3.4 port_value: 8080 - priority: 1 lb_endpoints: - endpoint: address: socket_address: address: 6.7.8.9 port_value: 8080 Mesh gateways route requests based solely on the SNI header tacked onto the TLS layer. Envoy currently only lets you configure the outbound SNI header at the cluster layer. If you try to failover through a mesh gateway you ideally would configure the SNI value per endpoint, but that's not possible in envoy today. This PR introduces a simpler way around the problem for now: 1. We identify any target of failover that will use mesh gateway mode local or remote and then further isolate any resolver node in the compiled discovery chain that has a failover destination set to one of those targets. 2. For each of these resolvers we will perform a small measurement of comparative healths of the endpoints that come back from the health API for the set of primary target and serial failover targets. We walk the list of targets in order and if any endpoint is healthy we return that target, otherwise we move on to the next target. 3. The CDS and EDS endpoints both perform the measurements in (2) for the affected resolver nodes. 4. For CDS this measurement selects which TLS SNI field to use for the cluster (note the cluster is always going to be named for the primary target) 5. For EDS this measurement selects which set of endpoints will populate the cluster. Priority tiered failover is ignored. One of the big downsides to this approach to failover is that the failover detection and correction is going to be controlled by consul rather than deferring that entirely to the data plane as with the prior version. This also means that we are bound to only failover using official health signals and cannot make use of data plane signals like outlier detection to affect failover. In this specific scenario the lack of data plane signals is ok because the effectiveness is already muted by the fact that the ultimate destination endpoints will have their data plane signals scrambled when they pass through the mesh gateway wrapper anyway so we're not losing much. Another related fix is that we now use the endpoint health from the underlying service, not the health of the gateway (regardless of failover mode).	5 years ago
R.B. Boyer	6393edba53	connect: reconcile how upstream configuration works with discovery chains (#6225 ) * connect: reconcile how upstream configuration works with discovery chains The following upstream config fields for connect sidecars sanely integrate into discovery chain resolution: - Destination Namespace/Datacenter: Compilation occurs locally but using different default values for namespaces and datacenters. The xDS clusters that are created are named as they normally would be. - Mesh Gateway Mode (single upstream): If set this value overrides any value computed for any resolver for the entire discovery chain. The xDS clusters that are created may be named differently (see below). - Mesh Gateway Mode (whole sidecar): If set this value overrides any value computed for any resolver for the entire discovery chain. If this is specifically overridden for a single upstream this value is ignored in that case. The xDS clusters that are created may be named differently (see below). - Protocol (in opaque config): If set this value overrides the value computed when evaluating the entire discovery chain. If the normal chain would be TCP or if this override is set to TCP then the result is that we explicitly disable L7 Routing and Splitting. The xDS clusters that are created may be named differently (see below). - Connect Timeout (in opaque config): If set this value overrides the value for any resolver in the entire discovery chain. The xDS clusters that are created may be named differently (see below). If any of the above overrides affect the actual result of compiling the discovery chain (i.e. "tcp" becomes "grpc" instead of being a no-op override to "tcp") then the relevant parameters are hashed and provided to the xDS layer as a prefix for use in naming the Clusters. This is to ensure that if one Upstream discovery chain has no overrides and tangentially needs a cluster named "api.default.XXX", and another Upstream does have overrides for "api.default.XXX" that they won't cross-pollinate against the operator's wishes.

R.B. Boyer	e039dfd7f8	connect: rework how the service resolver subset OnlyPassing flag works (#6173 ) The main change is that we no longer filter service instances by health, preferring instead to render all results down into EDS endpoints in envoy and merely label the endpoints as HEALTHY or UNHEALTHY.

R.B. Boyer	9138a97054	Fix bug in service-resolver redirects if the destination uses a default resolver. (#6122 ) Also: - add back an internal http endpoint to dump a compiled discovery chain for debugging purposes Before the CompiledDiscoveryChain.IsDefault() method would test: - is this chain just one resolver step? - is that resolver step just the default? But what I forgot to test: - is that resolver step for the same service that the chain represents? This last point is important because if you configured just one config entry: kind = "service-resolver" name = "web" redirect { service = "other" } and requested the chain for "web" you'd get back a default resolver for "other". In the xDS code the IsDefault() method is used to determine if this chain is "empty". If it is then we use the pre-discovery-chain logic that just uses data embedded in the Upstream object (and still lets the escape hatches function). In the example above that means certain parts of the xDS code were going to try referencing a cluster named "web..." despite the other parts of the xDS code maintaining clusters named "other...".	5 years ago

R.B. Boyer	20caa4f744	test: for envoy integration tests, wait until 's2' is healthy in consul before interrogating envoy (#6108 ) When the envoy healthy panic threshold was explicitly disabled as part of L7 traffic management it changed how envoy decided to load balance to endpoints in a cluster. This only matters when envoy is in "panic mode" aka "when you have a bunch of unhealthy endpoints". Panic mode sends traffic to unhealthy instances in certain circumstances. Note: Prior to explicitly disabling the healthy panic threshold, the default value is 50%. What was happening is that the test harness was bringing up consul the sidecars, and the service instances all at once and sometimes the proxies wouldn't have time to be checked by consul to be labeled as 'passing' in the catalog before a round of EDS happened. The xDS server in consul effectively queries /v1/health/connect/s2 and gets 1 result, but that one result has a 'critical' check so the xDS server sends back that endpoint labeled as UNHEALTHY. Envoy sees that 100% of the endpoints in the cluster are unhealthy and would enter panic mode and still send traffic to s2. This is why the test suites PRIOR to disabling the healthy panic threshold worked. They were _incorrectly_ passing. When the healthy panic threshol is disabled, envoy never enters panic mode in this situation and thus the cluster has zero healthy endpoints so load balancing goes nowhere and the tests fail. Why does this only affect the test suites for envoy 1.8.0? My guess is that https://github.com/envoyproxy/envoy/pull/4442 was merged into the 1.9.x series and somehow that plays a role. This PR modifies the bats scripts to explicitly wait until the upstream sidecar is healthy as measured by /v1/health/connect/s2?passing BEFORE trying to interrogate envoy which should make the tests less racy.	5 years ago
