Paul Banks	bb7145f27d	agent: add default weights to service in local state to prevent AE churn (#5126) ... * Add default weights when adding a service with no weights to local state to prevent constant AE re-sync. This fix was contributed by @42wim in https://github.com/hashicorp/consul/pull/5096 but was merged against the wrong base. This adds it to master and adds a test to cover the behaviour. * Fix tests that broke due to comparing internal state which now has default weights	6 years ago

Aestek	8709213d6e	Prevent status flap when re-registering a check (#4904) ... Fixes point `#2` of: https://github.com/hashicorp/consul/issues/4903 When registering a service each healthcheck status is saved and restored (https://github.com/hashicorp/consul/blob/master/agent/agent.go#L1914) to avoid unnecessary flaps in health state. This change extends this feature to single check registration by moving this protection in `AddCheck()` so that both `PUT /v1/agent/service/register` and `PUT /v1/agent/check/register` behave in the same idempotent way. #### Steps to reproduce 1. Register a check : ``` curl -X PUT \ http://127.0.0.1:8500/v1/agent/check/register \ -H 'Content-Type: application/json' \ -d '{ "Name": "my_check", "ServiceID": "srv", "Interval": "10s", "Args": ["true"] }' ``` 2. The check will initialize and change to `passing` 3. Run the same request again 4. The check status will quickly go from `critical` to `passing` (the delay for this transission is determined by https://github.com/hashicorp/consul/blob/master/agent/checks/check.go#L95)	6 years ago
Mitchell Hashimoto	f76022fa63	CA Provider Plugins (#4751) ... This adds the `agent/connect/ca/plugin` library for consuming/serving Connect CA providers as [go-plugin](https://github.com/hashicorp/go-plugin) plugins. This **does not** wire this up in any way to Consul itself, so this will not enable using these plugins yet. ## Why? We want to enable CA providers to be pluggable without modifying Consul so that any CA or PKI system can potentially back the Connect certificates. This CA system may also be used in the future for easier bootstrapping and internal cluster security. ### go-plugin The benefit of `go-plugin` is that for the plugin consumer, the fact that the interface implementation is communicating over multi-process RPC is invisible. Internals of Consul will continue to just use `ca.Provider` interface implementations as if they're local. For plugin _authors_, they simply have to implement the interface. The network/transport/process management issues are handled by go-plugin itself. The CA provider plugins support both `net/rpc` and gRPC transports. This enables easy authoring in any language. go-plugin handles the actual protocol handshake and connection. This is just a feature of go-plugin. `go-plugin` is already in production use for years by Packer, Terraform, Nomad, Vault, and Sentinel. We've shown stability for both desktop and server-side software. It is very mature. ## Implementation Details ### `map[string]interface{}` The `Configure` method passes a `map[string]interface{}`. This map contains only Go primitives and containers of primitives (no funcs, chans, etc.). For `net/rpc` we encode as-is using Gob. For gRPC we marshal to JSON and transmit as a `bytes` type. This is the same approach we take with Vault and other software. Note that this is just the transport protocol, the end software views it fully decoded. ### `x509.Certificate` and `CertificateRequest` We transmit the raw ASN.1 bytes and decode on the other side. Unit tests are verifying we get the same cert/csrs across the wire. ### Testing `go-plugin` exposes test helpers that enable testing the full plugin RPC over real loopback network connections. We test all endpoints for success and error for both `net/rpc` and gRPC. ### Vendoring This PR doesn't introduce vendoring for two reasons: 1. @banks's `f-envoy` branch introduces a lot of these and I didn't want conflict. 2. The library isn't actually used yet so it doesn't introduce compile-time errors (it does introduce test errors). ## Next Steps With this in place, we need to figure out the proper way to actually hook these up to Consul, load them, etc. This discussion can happen elsewhere, since regardless of approach this plugin library implementation is the exact same.	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
Aestek	5960974db1	[Fix] Services sometimes not being synced with acl_enforce_version_8 = false (#4771) ... Fixes: https://github.com/hashicorp/consul/issues/3676 This fixes a bug were registering an agent with a non-existent ACL token can prevent other services registered with a good token from being synced to the server when using `acl_enforce_version_8 = false`. ## Background When `acl_enforce_version_8` is off the agent does not check the ACL token validity before storing the service in its state. When syncing a service registered with a missing ACL token we fall into the default error handling case (https://github.com/hashicorp/consul/blob/master/agent/local/state.go#L1255) and stop the sync (https://github.com/hashicorp/consul/blob/master/agent/local/state.go#L1082) without setting its Synced property to true like in the permission denied case. This means that the sync will always stop at the faulty service(s). The order in which the services are synced is random since we iterate on a map. So eventually all services with good ACL tokens will be synced, this can however take some time and is influenced by the cluster size, the bigger the slower because retries are less frequent. Having a service in this state also prevent all further sync of checks as they are done after the services. ## Changes This change modify the sync process to continue even if there is an error. This fixes the issue described above as well as making the sync more error tolerant: if the server repeatedly refuses a service (the ACL token could have been deleted by the time the service is synced, the servers were upgraded to a newer version that has more strict checks on the service definition...). Then all services and check that can be synced will, and those that don't will be marked as errors in the logs instead of blocking the whole process.	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
