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

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.

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

Mitchell Hashimoto	37dde6d64a	agent/config: add managed proxy upstreams config to skip ... agent/config will turn [{}] into {} (single element maps into a single map) to work around HCL issues. These are resolved in HCL2 which I'm sure Consul will switch to eventually. This breaks the connect proxy configuration in service definition FILES since we call this patch function. For now, let's just special-case skip this. In the future we maybe Consul will adopt HCL2 and fix it, or we can do something else if we want. This works and is tested.	7 years ago

Pierre Souchay	0b7f620dc6	Allow to control the number of A/AAAA Record returned by DNS ... This allows to have randomized resource records (i.e. each answer contains only one IP, but the IP changes every request) for A, AAAA records. It will fix https://github.com/hashicorp/consul/issues/3355 and https://github.com/hashicorp/consul/issues/3937 See https://github.com/hashicorp/consul/issues/3937#issuecomment-370610509 for details. It basically add a new option called `a_record_limit` and will not return more than a_record_limit when performing A, AAAA or ANY DNS requests. The existing `udp_answer_limit` option is still working but should be considered as deprecated since it works only with DNS clients not supporting EDNS.	7 years ago

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 Schröder	94f58199b1	agent: add option to discard health output (#3562) ... * agent: add option to discard health output In high volatile environments consul will have checks with "noisy" output which changes every time even though the status does not change. Since the output is stored in the raft log every health check update unblocks a blocking call on health checks since the raft index has changed even though the status of the health checks may not have changed at all. By discarding the output of the health checks the users can choose a different tradeoff. Less visibility on why a check failed in exchange for a reduced change rate on the raft log. * agent: discard output also when adding a check * agent: add test for discard check output * agent: update docs * go vet * Adds discard_check_output to reloadable config table. * Updates the change log.	7 years ago
Frank Schröder	759ef8a1d4	config: add generic method to translate between CamelCase and snake_case (#3557) ... * doc: document discrepancy between id and CheckID * doc: document enable_tag_override change * config: add TranslateKeys helper TranslateKeys makes it easier to map between different representations of internal structures. It allows to recursively map alias keys to canonical keys in structured maps. * config: use TranslateKeys for config file This also adds support for 'enabletagoverride' and removes the need for a separate CheckID alias field. * config: remove dead code * agent: use TranslateKeys for FixupCheckType * agent: translate enable_tag_override during service registration * doc: add '.hcl' as valid extension * config: map ScriptArgs to args * config: add comment for TranslateKeys	7 years ago
James Phillips	bb12368eac	Makes RPC handling more robust when rolling servers. (#3561) ... * Adds client-side retry for no leader errors. This paves over the case where the client was connected to the leader when it loses leadership. * Adds a configurable server RPC drain time and a fail-fast path for RPCs. When a server leaves it gets removed from the Raft configuration, so it will never know who the new leader server ends up being. Without this we'd be doomed to wait out the RPC hold timeout and then fail. This makes things fail a little quicker while a sever is draining, and since we added a client retry AND since the server doing this has already shut down and left the Serf LAN, clients should retry against some other server. * Makes the RPC hold timeout configurable. * Reorders struct members. * Sets the RPC hold timeout default for test servers. * Bumps the leave drain time up to 5 seconds. * Robustifies retries with a simpler client-side RPC hold. * Reverts untended delete.	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. Fixes #2825 * do not allow unix sockets for DNS * improve bind and advertise addr error handling * go through builder using test coverage * minimal update to the docs * more coverage tests fixed * more tests * fix makefile * cleanup * fix port conflicts with external port server 'porter' * stop test server on error * do not run api test that change global ENV concurrently with the other tests * Run remaining api tests concurrently * no need for retry with the port number service * monkey patch race condition in go-sockaddr until we understand why that fails * monkey patch hcl decoder race condidtion until we understand why that fails * monkey patch spurious errors in strings.EqualFold from here * add test for hcl decoder race condition.
