# 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)

	statusCmd.PersistentFlags().BoolVar(&multiXdsOpts.XdsViaAgents, "xds-via-agents", false,
		"Access Istiod via the tap service of each agent")
	statusCmd.PersistentFlags().IntVar(&multiXdsOpts.XdsViaAgentsLimit, "xds-via-agents-limit", 100,
		"Maximum number of pods being visited by istioctl when `xds-via-agent` flag is true."+
			"To iterate all the agent pods without limit, set to 0")

	return statusCmd

                    // The result would be something like DEFAULT_JVM_OPTS='"-Xmx64m" "-Xms64m"'" \"-javaagent:$APP_HOME/lib/agents/foobar.jar\""
                    line + getAgentOptions("\$APP_HOME").joinToString(separator = " ", prefix = "\" ", postfix = "\"") {
                        // Wrap the agent switch in double quotes, as the expanded APP_HOME may contain spaces.

    * Para que isso funcione, um único componente (programa) em execução no servidor, ouvindo no endereço IP público, deve ter todos os certificados HTTPS no servidor.
* Depois de obter uma conexão segura, o protocolo de comunicação ainda é HTTP.
    * Os conteúdos são criptografados, embora sejam enviados com o protocolo HTTP.
