Chris Piraino	3feae7f77b	Report node/service usage metrics from every server Using the newly provided state store methods, we periodically emit usage metrics from the servers. We decided to emit these metrics from all servers, not just the leader, because that means we do not have to care about leader election flapping causing metrics turbulence, and it seems reasonable for each server to emit its own view of the state, even if they should always converge rapidly.	4 years ago
Daniel Nephin	edddc95e0f	logging: Remove t.Parallel from tests The tests all run fast enough that we do not get any advantage from using Parallel. The one test that was slow used a long sleep. Changing the sleep to a few milliseconds speeds up the test considerably.	4 years ago

Daniel Nephin	f2373a5575	logging: move init of grpclog This line initializes global state. Moving it out of the constructor and closer to where logging is setup helps keep related things together.	4 years ago
Daniel Nephin	33c401a16e	logging: Setup accept io.Writer instead of []io.Writer Also accept a non-pointer Config, since the config is not modified	4 years ago
Daniel Nephin	5d4df54296	agent: extract dependency creation from New With this change, Agent.New() accepts many of the dependencies instead of creating them in New. Accepting fully constructed dependencies from a constructor makes the type easier to test, and easier to change. There are still a number of dependencies created in Start() which can be addressed in a follow up.	4 years ago
Daniel Nephin	d68edcecf4	testing: Remove all the defer os.Removeall Now that testutil uses t.Cleanup to remove the directory the caller no longer has to manage the removal	4 years ago
Daniel Nephin	0420d91cdd	Remove LogOutput from Agent Now that it is no longer used, we can remove this unnecessary field. This is a pre-step in cleanup up RuntimeConfig->Consul.Config, which is a pre-step to adding a gRPCHandler component to Server for streaming. Removing this field also allows us to remove one of the return values from logging.Setup.	4 years ago
Matt Keeler	3dbbd2d37d	Implement Client Agent Auto Config There are a couple of things in here. First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism. This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.	4 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
