Daniel Upton	37ccbd2826	proxycfg: server-local intentions data source ... This is the OSS portion of enterprise PR 2141. This commit provides a server-local implementation of the `proxycfg.Intentions` interface that sources data from streaming events. It adds events for the `service-intentions` config entry type, and then consumes event streams (via materialized views) for the service's explicit intentions and any applicable wildcard intentions, merging them into a single list of intentions. An alternative approach I considered was to consume _all_ intention events (via `SubjectWildcard`) and filter out the irrelevant ones. This would admittedly remove some complexity in the `agent/proxycfg-glue` package but at the expense of considerable overhead from waking potentially many thousands of connect proxies every time any intention is updated.	2 years ago
Daniel Upton	653b8c4f9d	proxycfg: server-local config entry data sources ... This is the OSS portion of enterprise PR 2056. This commit provides server-local implementations of the proxycfg.ConfigEntry and proxycfg.ConfigEntryList interfaces, that source data from streaming events. It makes use of the LocalMaterializer type introduced for peering replication, adding the necessary support for authorization. It also adds support for "wildcard" subscriptions (within a topic) to the event publisher, as this is needed to fetch service-resolvers for all services when configuring mesh gateways. Currently, events will be emitted for just the ingress-gateway, service-resolver, and mesh config entry types, as these are the only entries required by proxycfg — the events will be emitted on topics named IngressGateway, ServiceResolver, and MeshConfig topics respectively. Though these events will only be consumed "locally" for now, they can also be consumed via the gRPC endpoint (confirmed using grpcurl) so using them from client agents should be a case of swapping the LocalMaterializer for an RPCMaterializer.	2 years ago
