Matt Keeler	76cf54068b	Expand the QueryOptions and QueryMeta interfaces (#6545) ... In a previous PR I made it so that we had interfaces that would work enough to allow blockingQueries to work. However to complete this we need all fields to be settable and gettable. Notes: • If Go ever gets contracts/generics then we could get rid of all the Getters/Setters • protoc / protoc-gen-gogo are going to generate all the getters for us. • I copied all the getters/setters from the protobuf funcs into agent/structs/protobuf_compat.go • Also added JSON marshaling funcs that use jsonpb for protobuf types.	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
Matt Keeler	51dcd126b7	Add support for implementing new requests with protobufs instea… (#6502) ... * Add build system support for protobuf generation This is done generically so that we don’t have to keep updating the makefile to add another proto generation. Note: anything not in the vendor directory and with a .proto extension will be run through protoc if the corresponding namespace.pb.go file is not up to date. If you want to rebuild just a single proto file you can do so with: make proto-rebuild PROTOFILES=<list of proto files to rebuild> Providing the PROTOFILES var will override the default behavior of finding all the .proto files. * Start adding types to the agent/proto package These will be needed for some other work and are by no means comprehensive. * Add ability to resolve/fixup the agentpb.ACLLinks structure in the state store. * Use protobuf marshalling of raft requests instead of msgpack for protoc generated types. This does not change any encoding of existing types. * Removed structs package automatically encoding with protobuf marshalling Instead the caller of raftApply that wants to opt-in to protobuf encoding will have to call `raftApplyProtobuf` * Run update-vendor to fixup modules.txt Nothing changed as far as dependencies go but the ordering of modules in that file depends on the time they are first seen and its not alphabetical. * Rename some things and implement the structs.RPCInfo interface bits agentpb.QueryOptions and agentpb.WriteRequest implement 3 of the 4 RPCInfo funcs and the new TargetDatacenter message type implements the fourth. * Use the right encoding function. * Renamed agent/proto package to agent/agentpb to prevent package name conflicts * Update modules.txt to fix ordering * Change blockingQuery to take in interfaces for the query options and meta * Add %T to error output. * Add/Update some comments	5 years ago

R.B. Boyer	ae79cdab1b	connect: introduce ExternalSNI field on service-defaults (#6324) ... Compiling this will set an optional SNI field on each DiscoveryTarget. When set this value should be used for TLS connections to the instances of the target. If not set the default should be used. Setting ExternalSNI will disable mesh gateway use for that target. It also disables several service-resolver features that do not make sense for an external service.	5 years ago
R.B. Boyer	1a485011d0	connect: updating a service-defaults config entry should leave an unset protocol alone (#6342) ... If the entry is updated for reasons other than protocol it is surprising that the value is explicitly persisted as 'tcp' rather than leaving it empty and letting it fall back dynamically on the proxy-defaults value.	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	f02924fafe	connect: simplify the compiled discovery chain data structures (#6242) ... This should make them better for sending over RPC or the API. Instead of a chain implemented explicitly like a linked list (nodes holding pointers to other nodes) instead switch to a flat map of named nodes with nodes linking other other nodes by name. The shipped structure is just a map and a string to indicate which key to start from. Other changes: * inline the compiler option InferDefaults as true * introduce compiled target config to avoid needing to send back additional maps of Resolvers; future target-specific compiled state can go here * move compiled MeshGateway out of the Resolver and into the TargetConfig where it makes more sense.	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	8564b6bb38	connect: validate upstreams and prevent duplicates (#6224) ... * connect: validate upstreams and prevent duplicates * Actually run Upstream.Validate() instead of ignoring it as dead code. * Prevent two upstreams from declaring the same bind address and port. It wouldn't work anyway. * Prevent two upstreams from being declared that use the same type+name+namespace+datacenter. Due to how the Upstream.Identity() function worked this ended up mostly being enforced in xDS at use-time, but it should be enforced more clearly at register-time.	5 years ago

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. When OnlyPassing is set to true we will force consul checks in a 'warning' state to render as UNHEALTHY in envoy. Fixes #6171	5 years ago

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	67a36e3452	handle structs.ConfigEntry decoding similarly to api.ConfigEntry decoding (#6106) ... Both 'consul config write' and server bootstrap config entries take a decoding detour through mapstructure on the way from HCL to an actual struct. They both may take in snake_case or CamelCase (for consistency) so need very similar handling. Unfortunately since they are operating on mirror universes of structs (api.* vs structs.*) the code cannot be identitical, so try to share the kind-configuration and duplicate the rest for now.	5 years ago
