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	8564b6bb38	connect: validate upstreams and prevent duplicates (#6224) ... * connect: validate upstreams and prevent duplicates * Actually run Upstream.Validate() instead of ignoring it as dead code. * Prevent two upstreams from declaring the same bind address and port. It wouldn't work anyway. * Prevent two upstreams from being declared that use the same type+name+namespace+datacenter. Due to how the Upstream.Identity() function worked this ended up mostly being enforced in xDS at use-time, but it should be enforced more clearly at register-time.	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
Paul Banks	0cfb6051ea	Add integration test for central config; fix central config WIP (#5752) ... * Add integration test for central config; fix central config WIP * Add integration test for central config; fix central config WIP * Set proxy protocol correctly and begin adding upstream support * Add upstreams to service config cache key and start new notify watcher if they change. This doesn't update the tests to pass though. * Fix some merging logic get things working manually with a hack (TODO fix properly) * Simplification to not allow enabling sidecars centrally - it makes no sense without upstreams anyway * Test compile again and obvious ones pass. Lots of failures locally not debugged yet but may be flakes. Pushing up to see what CI does * Fix up service manageer and API test failures * Remove the enable command since it no longer makes much sense without being able to turn on sidecar proxies centrally * Remove version.go hack - will make integration test fail until release * Remove unused code from commands and upstream merge * Re-bump version to 1.5.0	6 years ago

Matt Keeler	18b29c45c4	New ACLs (#4791) ... This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week. Description At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers. On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though. Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though. All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management. Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are: A server running the new system must still support other clients using the legacy system. A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system. The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode. So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.	6 years ago
Pierre Souchay	51b33ef015	[Performance On Large clusters] Reduce updates on large services (#4720) ... * [Performance On Large clusters] Checks do update services/nodes only when really modified to avoid too many updates on very large clusters In a large cluster, when having a few thousands of nodes, the anti-entropy mechanism performs lots of changes (several per seconds) while there is no real change. This patch wants to improve this in order to increase Consul scalability when using many blocking requests on health for instance. * [Performance for large clusters] Only updates index of service if service is really modified * [Performance for large clusters] Only updates index of nodes if node is really modified * Added comments / ensure IsSame() has clear semantics * Avoid having modified boolean, return nil directly if stutures are Same * Fixed unstable unit tests TestLeader_ChangeServerID * Rewrite TestNode_IsSame() for better readability as suggested by @banks * Rename ServiceNode.IsSame() into IsSameService() + added unit tests * Do not duplicate TestStructs_ServiceNode_Conversions() and increase test coverage of IsSameService * Clearer documentation in IsSameService * Take into account ServiceProxy into ServiceNode.IsSameService() * Fixed IsSameService() with all new structures	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
