# Istio Agent

This document describes the internal architecture of Istio agent.

## High Level overview

![High Level overview](docs/overview.svg)

At a high level, the Istio agent acts as an intermediate proxy between Istiod and Envoy. This is done
at two levels. For distributing workload certificates, Envoy will send [SDS](https://www.envoyproxy.io/docs/envoy/latest/configuration/security/secret)

# 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

  istioctl dashboard istiod-debug istiod-123-456.istio-system

  # Open Istio debug web UI for the istiod-56dd66799-jfdvs pod in a custom namespace
  istioctl dashboard istiod-debug istiod-123-456 -n custom-ns

  # Open Istio debug web UI for any Istiod pod
  istioctl dashboard istiod-debug deployment/istiod.istio-system

  # with short syntax
  istioctl dash istiod-debug pilot-123-456.istio-system
