Otherwise users of the latest version of the api submodule cannot interact with older versions of Consul, because a new api client would send keys that the older Consul doesn't recognize yet.	4 years ago
freddygv	7bd51ff536	Replace TransparentProxy bool with ProxyMode ... This PR replaces the original boolean used to configure transparent proxy mode. It was replaced with a string mode that can be set to: - "": Empty string is the default for when the setting should be defaulted from other configuration like config entries. - "direct": Direct mode is how applications originally opted into the mesh. Proxy listeners need to be dialed directly. - "transparent": Transparent mode enables configuring Envoy as a transparent proxy. Traffic must be captured and redirected to the inbound and outbound listeners. This PR also adds a struct for transparent proxy specific configuration. Initially this is not stored as a pointer. Will revisit that decision before GA.	4 years ago

R.B. Boyer	58387fef0a	server: config entry replication now correctly uses namespaces in comparisons (#9024) ... Previously config entries sharing a kind & name but in different namespaces could occasionally cause "stuck states" in replication because the namespace fields were ignored during the differential comparison phase. Example: Two config entries written to the primary: kind=A,name=web,namespace=bar kind=A,name=web,namespace=foo Under the covers these both get saved to memdb, so they are sorted by all 3 components (kind,name,namespace) during natural iteration. This means that before the replication code does it's own incomplete sort, the underlying data IS sorted by namespace ascending (bar comes before foo). After one pass of replication the primary and secondary datacenters have the same set of config entries present. If "kind=A,name=web,namespace=bar" were to be deleted, then things get weird. Before replication the two sides look like: primary: [ kind=A,name=web,namespace=foo ] secondary: [ kind=A,name=web,namespace=bar kind=A,name=web,namespace=foo ] The differential comparison phase walks these two lists in sorted order and first compares "kind=A,name=web,namespace=foo" vs "kind=A,name=web,namespace=bar" and falsely determines they are the SAME and are thus cause an update of "kind=A,name=web,namespace=foo". Then it compares "<nothing>" with "kind=A,name=web,namespace=foo" and falsely determines that the latter should be DELETED. During reconciliation the deletes are processed before updates, and so for a brief moment in the secondary "kind=A,name=web,namespace=foo" is erroneously deleted and then immediately restored. Unfortunately after this replication phase the final state is identical to the initial state, so when it loops around again (rate limited) it repeats the same set of operations indefinitely.	4 years ago

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	6393edba53	connect: reconcile how upstream configuration works with discovery chains (#6225) ... * connect: reconcile how upstream configuration works with discovery chains The following upstream config fields for connect sidecars sanely integrate into discovery chain resolution: - Destination Namespace/Datacenter: Compilation occurs locally but using different default values for namespaces and datacenters. The xDS clusters that are created are named as they normally would be. - Mesh Gateway Mode (single upstream): If set this value overrides any value computed for any resolver for the entire discovery chain. The xDS clusters that are created may be named differently (see below). - Mesh Gateway Mode (whole sidecar): If set this value overrides any value computed for any resolver for the entire discovery chain. If this is specifically overridden for a single upstream this value is ignored in that case. The xDS clusters that are created may be named differently (see below). - Protocol (in opaque config): If set this value overrides the value computed when evaluating the entire discovery chain. If the normal chain would be TCP or if this override is set to TCP then the result is that we explicitly disable L7 Routing and Splitting. The xDS clusters that are created may be named differently (see below). - Connect Timeout (in opaque config): If set this value overrides the value for any resolver in the entire discovery chain. The xDS clusters that are created may be named differently (see below). If any of the above overrides affect the actual result of compiling the discovery chain (i.e. "tcp" becomes "grpc" instead of being a no-op override to "tcp") then the relevant parameters are hashed and provided to the xDS layer as a prefix for use in naming the Clusters. This is to ensure that if one Upstream discovery chain has no overrides and tangentially needs a cluster named "api.default.XXX", and another Upstream does have overrides for "api.default.XXX" that they won't cross-pollinate against the operator's wishes.

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	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

Paul Banks	0f27ffd163	Proxy Config Manager (#4729) ... * Proxy Config Manager This component watches for local state changes on the agent and ensures that each service registered locally with Kind == connect-proxy has it's state being actively populated in the cache. This serves two purposes: 1. For the built-in proxy, it ensures that the state needed to accept connections is available in RAM shortly after registration and likely before the proxy actually starts accepting traffic. 2. For (future - next PR) xDS server and other possible future proxies that require _push_ based config discovery, this provides a mechanism to subscribe and be notified about updates to a proxy instance's config including upstream service discovery results. * Address review comments * Better comments; Better delivery of latest snapshot for slow watchers; Embed Config * Comment typos * Add upstream Stringer for funsies	6 years ago
