R.B. Boyer	25ba9c147a	xds: ensure that all connect timeout configs can apply equally to tproxy direct dial connections (#12711 ) Just like standard upstreams the order of applicability in descending precedence: 1. caller's `service-defaults` upstream override for destination 2. caller's `service-defaults` upstream defaults 3. destination's `service-resolver` ConnectTimeout 4. system default of 5s Co-authored-by: mrspanishviking <kcardenas@hashicorp.com>	3 years ago

freddygv	eacb73cb78	Remove useInDatacenter from disco chain requests useInDatacenter was used to determine whether the mesh gateway mode of the upstream should be returned in the discovery chain target. This commit makes it so that the mesh gateway mode is returned every time, and it is up to the caller to decide whether mesh gateways should be watched or used.	3 years ago

Daniel Nephin	b9e60c0775	testing: skip slow tests with -short Add a skip condition to all tests slower than 100ms. This change was made using `gotestsum tool slowest` with data from the last 3 CI runs of master. See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests With this change: ``` $ time go test -count=1 -short ./agent ok github.com/hashicorp/consul/agent 0.743s real 0m4.791s $ time go test -count=1 -short ./agent/consul ok github.com/hashicorp/consul/agent/consul 4.229s real 0m8.769s ```	4 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	c395affc93	connect: expose an API endpoint to compile the discovery chain (#6248 ) In addition to exposing compilation over the API cleaned up the structures that would be exchanged to be cleaner and easier to support and understand. Also removed ability to configure the envoy OverprovisioningFactor.	5 years ago
