Chris Piraino	f3b54fa535	Allow configuration of upstream connection limits in Envoy (#6829 ) * Adds 'limits' field to the upstream configuration of a connect proxy This allows a user to configure the envoy connect proxy with 'max_connections', 'max_queued_requests', and 'max_concurrent_requests'. These values are defined in the local proxy on a per-service instance basis and should thus NOT be thought of as a global-level or even service-level value.	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. 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	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

Frank Schroeder	c94751ad43	test: replace porter tool with freeport lib This patch removes the porter tool which hands out free ports from a given range with a library which does the same thing. The challenge for acquiring free ports in concurrent go test runs is that go packages are tested concurrently and run in separate processes. There has to be some inter-process synchronization in preventing processes allocating the same ports. freeport allocates blocks of ports from a range expected to be not in heavy use and implements a system-wide mutex by binding to the first port of that block for the lifetime of the application. Ports are then provided sequentially from that block and are tested on localhost before being returned as available.	7 years ago

Frank Schröder	12216583a1	New config parser, HCL support, multiple bind addrs (#3480 ) * new config parser for agent This patch implements a new config parser for the consul agent which makes the following changes to the previous implementation: * add HCL support * all configuration fragments in tests and for default config are expressed as HCL fragments * HCL fragments can be provided on the command line so that they can eventually replace the command line flags. * HCL/JSON fragments are parsed into a temporary Config structure which can be merged using reflection (all values are pointers). The existing merge logic of overwrite for values and append for slices has been preserved. * A single builder process generates a typed runtime configuration for the agent. The new implementation is more strict and fails in the builder process if no valid runtime configuration can be generated. Therefore, additional validations in other parts of the code should be removed. The builder also pre-computes all required network addresses so that no address/port magic should be required where the configuration is used and should therefore be removed. * Upgrade github.com/hashicorp/hcl to support int64 * improve error messages * fix directory permission test * Fix rtt test * Fix ForceLeave test * Skip performance test for now until we know what to do * Update github.com/hashicorp/memberlist to update log prefix * Make memberlist use the default logger * improve config error handling * do not fail on non-existing data-dir * experiment with non-uniform timeouts to get a handle on stalled leader elections * Run tests for packages separately to eliminate the spurious port conflicts * refactor private address detection and unify approach for ipv4 and ipv6.
