Derek Menteer	1255a8a20d	Add separate grpc_tls port. ... To ease the transition for users, the original gRPC port can still operate in a deprecated mode as either plain-text or TLS mode. This behavior should be removed in a future release whenever we no longer support this. The resulting behavior from this commit is: `ports.grpc > 0 && ports.grpc_tls > 0` spawns both plain-text and tls ports. `ports.grpc > 0 && grpc.tls == undefined` spawns a single plain-text port. `ports.grpc > 0 && grpc.tls != undefined` spawns a single tls port (backwards compat mode).	2 years ago

Daniel Nephin	1dcafa51a4	config: make config.TestLoad_FullConfig use config.Load ... This commit makes a number of changes that should make TestLoad_FullConfig easier to work with, and make the test more like real world scenarios. * use separate files in testdata/ dir to store the config source. Separate files are much easier to edit because editors can syntax highlight json/hcl, and it makes strings easier to find. Previously trying to find strings would match strings used in other tests. * use the exported config.Load interface instead of internal NewBuilder and BuildAndValidate. * remove the tail config overrides, which are only necessary with nonZero works.	4 years ago
Daniel Nephin	97a577502d	config: improve the interface of Load ... This commit reduces the interface to Load() a bit, in preparation for unexporting NewBuilder and having everything call Load. The three arguments are reduced to a single argument by moving the other two into the options struct. The three return values are reduced to two by moving the RuntimeConfig and Warnings into a LoadResult struct.	4 years ago
Daniel Nephin	78f767e78c	config: move testing shims to BuilderOpts ... And remove the devMode field from builder. This change helps make the Builder state more explicit by moving inputs to the BuilderOps struct, leaving only fields that can change during Builder.Build on the Builder struct.	4 years ago

Daniel Nephin	219790ca49	config: Make ConfigFormat not a pointer ... The nil value was never used. We can avoid a bunch of complications by making the field a string value instead of a pointer. This change is in preparation for fixing a silent config failure.	5 years ago
Daniel Nephin	77101eee82	config: rename Flags to BuilderOpts ... Flags is an overloaded term in this context. It generally is used to refer to command line flags. This struct, however, is a data object used as input to the construction. It happens to be partially populated by command line flags, but otherwise has very little to do with them. Renaming this struct should make the actual responsibility of this struct more obvious, and remove the possibility that it is confused with command line flags. This change is in preparation for adding additional fields to BuilderOpts.	5 years ago
Daniel Nephin	85e0338136	config: remove Args field from Flags ... This field was populated for one reason, to test that it was empty. Of all the callers, only a single one used this functionality. The rest constructed a `Flags{}` struct which did not set Args. I think this shows that the logic was in the wrong place. Only the agent command needs to care about validating the args. This commit removes the field, and moves the logic to the one caller that cares. Also fix some comments.	5 years ago
Pierre Souchay	e9d176db2a	Allow to restrict servers that can join a given Serf Consul cluster. (#7628) ... Based on work done in https://github.com/hashicorp/memberlist/pull/196 this allows to restrict the IP ranges that can join a given Serf cluster and be a member of the cluster. Restrictions on IPs can be done separatly using 2 new differents flags and config options to restrict IPs for LAN and WAN Serf.	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

Sarah Christoff	d3d92d76f3	ui: modify content path (#5950) ... * Add ui-content-path flag * tests complete, regex validator on string, index.html updated * cleaning up debugging stuff * ui: Enable ember environment configuration to be set via the go binary at runtime (#5934) * ui: Only inject {{.ContentPath}} if we are makeing a prod build... ...otherwise we just use the current rootURL This gets injected into a <base /> node which solves the assets path problem but not the ember problem * ui: Pull out the <base href=""> value and inject it into ember env See previous commit: The <base href=""> value is 'sometimes' injected from go at index serve time. We pass this value down to ember by overwriting the ember config that is injected via a <meta> tag. This has to be done before ember bootup. Sometimes (during testing and development, basically not production) this is injected with the already existing value, in which case this essentially changes nothing. The code here is slightly abstracted away from our specific usage to make it easier for anyone else to use, and also make sure we can cope with using this same method to pass variables down from the CLI through to ember in the future. * ui: We can't use <base /> move everything to javascript (#5941) Unfortuantely we can't seem to be able to use <base> and rootURL together as URL paths will get doubled up (`ui/ui/`). This moves all the things that we need to interpolate with .ContentPath to the `startup` javascript so we can conditionally print out `{{.ContentPath}}` in lots of places (now we can't use base) * fixed when we serve index.html * ui: For writing a ContentPath, we also need to cope with testing... (#5945) ...and potentially more environments Testing has more additional things in a separate index.html in `tests/` This make the entire thing a little saner and uses just javascriopt template literals instead of a pseudo handbrake synatx for our templating of these files. Intead of just templating the entire file this way, we still only template `{{content-for 'head'}}` and `{{content-for 'body'}}` in this way to ensure we support other plugins/addons * build: Loosen up the regex for retrieving the CONSUL_VERSION (#5946) * build: Loosen up the regex for retrieving the CONSUL_VERSION 1. Previously the `sed` replacement was searching for the CONSUL_VERSION comment at the start of a line, it no longer does this to allow for indentation. 2. Both `grep` and `sed` where looking for the omment at the end of the line. We've removed this restriction here. We don't need to remove it right now, but if we ever put the comment followed by something here the searching would break. 3. Added `xargs` for trimming the resulting version string. We aren't using this already in the rest of the scripts, but we are pretty sure this is available on most systems. * ui: Fix erroneous variable, and also force an ember cache clean on build 1. We referenced a variable incorrectly here, this fixes that. 2. We also made sure that every `make` target clears ember's `tmp` cache to ensure that its not using any caches that have since been edited everytime we call a `make` target. * added docs, fixed encoding * fixed go fmt * Update agent/config/config.go Co-Authored-By: R.B.

Frank Schröder	874e350b2f	config: add -config-format option (#3626) ... * config: refactor ReadPath(s) methods without side-effects Return the sources instead of modifying the state. * config: clean data dir before every test * config: add tests for config-file and config-dir * config: add -config-format option Starting with Consul 1.0 all config files must have a '.json' or '.hcl' extension to make it unambigous how the data should be parsed. Some automation tools generate temporary files by appending a random string to the generated file which obfuscates the extension and prevents the file type detection. This patch adds a -config-format option which can be used to override the auto-detection behavior by forcing all config files or all files within a config directory independent of their extension to be interpreted as of this format. Fixes #3620	7 years ago
Frank Schroeder	b97ab367f4	config: return error on extra command line arguments (#3397) ... The `consul agent` command was ignoring extra command line arguments which can lead to confusion when the user has for example forgotten to add a dash in front of an argument or is not using an `=` when setting boolean flags to `true`. `-bootstrap true` is not the same as `-bootstrap=true`, for example. Since all command line flags are known and we don't expect unparsed arguments we can return an error. However, this may make it slightly more difficult in the future if we ever wanted to have these kinds of arguments. Fixes #3397	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.
