## Ambient mode details

Fundamentally, this component is responsible for the following:

- Sets up redirection with newly-started (or newly-added, previously-started) application pods such that traffic from application pods is forwarded to the local node's ztunnel pod.

	cmd.PersistentFlags().DurationVar(&args.ReadinessTimeout, "readiness-timeout", 300*time.Second,
		"Maximum time to wait for Istio resources in each component to be ready.")
	cmd.PersistentFlags().BoolVarP(&args.SkipConfirmation, "skip-confirmation", "y", false, skipConfirmationFlagHelpStr)
	cmd.PersistentFlags().BoolVar(&args.Force, "force", false, ForceFlagHelpStr)

# Ztunnel

This document provides an overview of the architecture and design decisions around Ztunnel, the node-proxy component in ambient mode.

## Background and motivation

Motivations to implement ztunnel generally came from two areas.

First, and most importantly, it serves as a means to implement the real goal: waypoints.
