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	f3d9b999ee	Add tagged addresses for services (#5965) ... This allows addresses to be tagged at the service level similar to what we allow for nodes already. The address translation that can be enabled with the `translate_wan_addrs` config was updated to take these new addresses into account as well.	6 years ago
Matt Keeler	afa1cc98d1	Implement data filtering of some endpoints (#5579) ... Fixes: #4222 # Data Filtering This PR will implement filtering for the following endpoints: ## Supported HTTP Endpoints - `/agent/checks` - `/agent/services` - `/catalog/nodes` - `/catalog/service/:service` - `/catalog/connect/:service` - `/catalog/node/:node` - `/health/node/:node` - `/health/checks/:service` - `/health/service/:service` - `/health/connect/:service` - `/health/state/:state` - `/internal/ui/nodes` - `/internal/ui/services` More can be added going forward and any endpoint which is used to list some data is a good candidate. ## Usage When using the HTTP API a `filter` query parameter can be used to pass a filter expression to Consul. Filter Expressions take the general form of: ``` <selector> == <value> <selector> != <value> <value> in <selector> <value> not in <selector> <selector> contains <value> <selector> not contains <value> <selector> is empty <selector> is not empty not <other expression> <expression 1> and <expression 2> <expression 1> or <expression 2> ``` Normal boolean logic and precedence is supported. All of the actual filtering and evaluation logic is coming from the [go-bexpr](https://github.com/hashicorp/go-bexpr) library ## Other changes Adding the `Internal.ServiceDump` RPC endpoint. This will allow the UI to filter services better.	6 years ago

Matt Keeler	118adbb123	ACL Token Persistence and Reloading (#5328) ... This PR adds two features which will be useful for operators when ACLs are in use. 1. Tokens set in configuration files are now reloadable. 2. If `acl.enable_token_persistence` is set to `true` in the configuration, tokens set via the `v1/agent/token` endpoint are now persisted to disk and loaded when the agent starts (or during configuration reload) Note that token persistence is opt-in so our users who do not want tokens on the local disk will see no change. Some other secondary changes: * Refactored a bunch of places where the replication token is retrieved from the token store. This token isn't just for replicating ACLs and now it is named accordingly. * Allowed better paths in the `v1/agent/token/` API. Instead of paths like: `v1/agent/token/acl_replication_token` the path can now be just `v1/agent/token/replication`. The old paths remain to be valid. * Added a couple new API functions to set tokens via the new paths. Deprecated the old ones and pointed to the new names. The names are also generally better and don't imply that what you are setting is for ACLs but rather are setting ACL tokens. There is a minor semantic difference there especially for the replication token as again, its no longer used only for ACL token/policy replication. The new functions will detect 404s and fallback to using the older token paths when talking to pre-1.4.3 agents. * Docs updated to reflect the API additions and to show using the new endpoints. * Updated the ACL CLI set-agent-tokens command to use the non-deprecated APIs.	6 years ago
Grégoire Seux	4f62a3b528	Implement /v1/agent/health/service/<service name> endpoint (#3551) ... This endpoint aggregates all checks related to <service id> on the agent and return an appropriate http code + the string describing the worst check. This allows to cleanly expose service status to other component, hiding complexity of multiple checks. This is especially useful to use consul to feed a load balancer which would delegate health checking to consul agent. Exposing this endpoint on the agent is necessary to avoid a hit on consul servers and avoid decreasing resiliency (this endpoint will work even if there is no consul leader in the cluster).	6 years ago
Jack Pearkes	8c684db488	New command: consul debug (#4754) ... * agent/debug: add package for debugging, host info * api: add v1/agent/host endpoint * agent: add v1/agent/host endpoint * command/debug: implementation of static capture * command/debug: tests and only configured targets * agent/debug: add basic test for host metrics * command/debug: add methods for dynamic data capture * api: add debug/pprof endpoints * command/debug: add pprof * command/debug: timing, wg, logs to disk * vendor: add gopsutil/disk * command/debug: add a usage section * website: add docs for consul debug * agent/host: require operator:read * api/host: improve docs and no retry timing * command/debug: fail on extra arguments * command/debug: fixup file permissions to 0644 * command/debug: remove server flags * command/debug: improve clarity of usage section * api/debug: add Trace for profiling, fix profile * command/debug: capture profile and trace at the same time * command/debug: add index document * command/debug: use "clusters" in place of members * command/debug: remove address in output * command/debug: improve comment on metrics sleep * command/debug: clarify usage * agent: always register pprof handlers and protect This will allow us to avoid a restart of a target agent for profiling by always registering the pprof handlers. Given this is a potentially sensitive path, it is protected with an operator:read ACL and enable debug being set to true on the target agent. enable_debug still requires a restart. If ACLs are disabled, enable_debug is sufficient. * command/debug: use trace.out instead of .prof More in line with golang docs. * agent: fix comment wording * agent: wrap table driven tests in t.run()	6 years ago
R.B. Boyer	c310451b2b	cli: avoid passing envoy bootstrap configuration as arguments (#4747) ... Play a trick with CLOEXEC to pass the envoy bootstrap configuration as an open file descriptor to the exec'd envoy process. The file only briefly touches disk before being unlinked. We convince envoy to read from this open file descriptor by using the /dev/fd/$FDNUMBER mechanism to read the open file descriptor as a file. Because the filename no longer has an extension envoy's sniffing logic falls back on JSON instead of YAML, so the bootstrap configuration must be generated as JSON instead.	6 years ago
Paul Banks	e812f5516a	Add -sidecar-for and new /agent/service/:service_id endpoint (#4691) ... - A new endpoint `/v1/agent/service/:service_id` which is a generic way to look up the service for a single instance. The primary value here is that it: - **supports hash-based blocking** and so; - **replaces `/agent/connect/proxy/:proxy_id`** as the mechanism the built-in proxy uses to read its config. - It's not proxy specific and so works for any service. - It has a temporary shim to call through to the existing endpoint to preserve current managed proxy config defaulting behaviour until that is removed entirely (tested). - The built-in proxy now uses the new endpoint exclusively for it's config - The built-in proxy now has a `-sidecar-for` flag that allows the service ID of the _target_ service to be specified, on the condition that there is exactly one "sidecar" proxy (that is one that has `Proxy.DestinationServiceID` set) for the service registered. - Several fixes for edge cases for SidecarService - A fix for `Alias` checks - when running locally they didn't update their state until some external thing updated the target. If the target service has no checks registered as below, then the alias never made it past critical.	6 years ago
Paul Banks	1e7eace066	Add SidecarService Syntax sugar to Service Definition (#4686) ... * Added new Config for SidecarService in ServiceDefinitions. * WIP: all the code needed for SidecarService is written... none of it is tested other than config :). Need API updates too. * Test coverage for the new sidecarServiceFromNodeService method. * Test API registratrion with SidecarService * Recursive Key Translation 🤦 * Add tests for nested sidecar defintion arrays to ensure they are translated correctly * Use dedicated internal state rather than Service Meta for tracking sidecars for deregistration. Add tests for deregistration. * API struct for agent register. No other endpoint should be affected yet. * Additional test cases to cover updates to API registrations	6 years ago
Paul Banks	b83bbf248c	Add Proxy Upstreams to Service Definition (#4639) ... * Refactor Service Definition ProxyDestination. This includes: - Refactoring all internal structs used - Updated tests for both deprecated and new input for: - Agent Services endpoint response - Agent Service endpoint response - Agent Register endpoint - Unmanaged deprecated field - Unmanaged new fields - Managed deprecated upstreams - Managed new - Catalog Register - Unmanaged deprecated field - Unmanaged new fields - Managed deprecated upstreams - Managed new - Catalog Services endpoint response - Catalog Node endpoint response - Catalog Service endpoint response - Updated API tests for all of the above too (both deprecated and new forms of register) TODO: - config package changes for on-disk service definitions - proxy config endpoint - built-in proxy support for new fields * Agent proxy config endpoint updated with upstreams * Config file changes for upstreams. * Add upstream opaque config and update all tests to ensure it works everywhere. * Built in proxy working with new Upstreams config * Command fixes and deprecations * Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts... TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct. * Fix translated keys in API registration. ≈ * Fixes from docs - omit some empty undocumented fields in API - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally. * Documentation updates for Upstreams in service definition * Fixes for tests broken by many refactors. * Enable travis on f-connect branch in this branch too. * Add consistent Deprecation comments to ProxyDestination uses * Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs	6 years ago
Pierre Souchay	eddcf228ea	Implementation of Weights Data structures (#4468) ... * Implementation of Weights Data structures Adding this datastructure will allow us to resolve the issues #1088 and #4198 This new structure defaults to values: ``` { Passing: 1, Warning: 0 } ``` Which means, use weight of 0 for a Service in Warning State while use Weight 1 for a Healthy Service. Thus it remains compatible with previous Consul versions. * Implemented weights for DNS SRV Records * DNS properly support agents with weight support while server does not (backwards compatibility) * Use Warning value of Weights of 1 by default When using DNS interface with only_passing = false, all nodes with non-Critical healthcheck used to have a weight value of 1. While having weight.Warning = 0 as default value, this is probably a bad idea as it breaks ascending compatibility. Thus, we put a default value of 1 to be consistent with existing behaviour. * Added documentation for new weight field in service description * Better documentation about weights as suggested by @banks * Return weight = 1 for unknown Check states as suggested by @banks * Fixed typo (of -> or) in error message as requested by @mkeeler * Fixed unstable unit test TestRetryJoin * Fixed unstable tests * Fixed wrong Fatalf format in `testrpc/wait.go` * Added notes regarding DNS SRV lookup limitations regarding number of instances * Documentation fixes and clarification regarding SRV records with weights as requested by @banks * Rephrase docs	6 years ago

James Bardin	deb43fea6b	accept recv-only channels for cancellations (#3271) ... Cancellation channels are often derived from a Context, which returns a directional `<-chan struct{}` from Done(). In order to use this with parts of of the consul API, one is required to create a new channel and dispatch a separate goroutine to watch for context cancellation and close the new channel. Changing the signature for the methods that take cancellation channels will allow easier integration with existing uses of Context. Since the cancellation pattern only reads from these channels, there should be no backwards incompatibility with existing codebases, and most of the methods already accept only the correct type.	7 years ago
