Listeners
How Elchi models Envoy listeners (LDS) — bind addresses, filter chains, the HTTP Connection Manager, and TLS termination.
Routes
How Elchi models Envoy route configurations (RDS) — virtual hosts, match/route/redirect rules, and header manipulation.
Virtual Hosts
How Elchi models Envoy virtual hosts inside a route configuration — domains, per-vhost routes, retries, and header rules.
Clusters
How Elchi models Envoy clusters (CDS) — discovery type, load balancing, health checks, circuit breakers, and outlier detection.
Endpoints
How Elchi models Envoy endpoints (EDS) — the ClusterLoadAssignment, localities, priorities, weights, and their link to clusters.
Secrets & TLS
How Elchi models Envoy secrets (SDS) — TLS certificates, validation contexts, and the link to ACME-managed certificates.
Transport Sockets
How Elchi models Envoy transport sockets — downstream vs upstream TLS/mTLS on listeners and clusters, plus QUIC and Proxy Protocol.
Filters
How Elchi models Envoy filters — the listener, network, HTTP, and UDP filter categories the UI exposes, and where WAF and ext_proc fit.
Extensions
How Elchi surfaces Envoy typed_config extensions — reusable, separately-managed configs referenced by other resources.
Bootstrap
The Envoy bootstrap config Elchi generates for each proxy — node identity, admin, static resources, and the ADS connection back to the control-plane.
