# Architecture of Istiod

This document describes the high level architecture of the Istio control plane, Istiod.
Istiod is structured as a modular monolith, housing a wide range of functionality from certificate signing, proxy configuration (XDS), traditional Kubernetes controllers, and more.

## Proxy Configuration

  // +optional
  repeated string hosts = 1;

  // SecretName is the name of the secret used to terminate SSL traffic on 443.
  // Field is left optional to allow SSL routing based on SNI hostname alone.
  // If the SNI host in a listener conflicts with the "Host" header field used
  // by an IngressRule, the SNI host is used for termination and value of the
  // Host header is used for routing.
  // +optional

  // the network identity of the set. Pods get DNS/hostnames that follow the
  // pattern: pod-specific-string.serviceName.default.svc.cluster.local
  // where "pod-specific-string" is managed by the StatefulSet controller.
  optional string serviceName = 5;

  // podManagementPolicy controls how pods are created during initial scale up,
  // when replacing pods on nodes, or when scaling down. The default policy is

# permissions to verify the webhook is ready and rejecting
# invalid config. We use --server-dry-run so no config is persisted.
