- pod label "istio.io/dataplane-mode" is not "none"
- sidecar interception is enabled if:
    - "istio-init" container is not present in the pod.
    - istio-proxy container exists and
        - does not have DISABLE_ENVOY environment variable (which triggers proxyless mode)
        - has a istio-proxy container, with first 2 args "proxy" and "sidecar" - or less then 2 args, or first arg not proxy.
        - "sidecar.istio.io/inject" is not false

# 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

# Istio Operator

The istio/operator repo is part of istio/istio from 1.5 onwards.
You can [contribute](../CONTRIBUTING.md) by picking an
[unassigned open issue](https://github.com/istio/istio/issues?q=is%3Aissue+is%3Aopen+label%3Aarea%2Fenvironments%2Foperator+no%3Aassignee),

	cp manifests/charts/istio-control/istio-discovery/files/gateway-injection-template.yaml manifests/charts/istiod-remote/files
	cp manifests/charts/istio-control/istio-discovery/templates/istiod-injector-configmap.yaml manifests/charts/istiod-remote/templates

  * Explicitly opting into behavioral changes can be acceptable. For example, introducing Istio multi-cluster semantics.
* Ensure traffic between mesh workloads is securely encrypted with an Istio identity.
* Be lightweight enough to not limit adoption.
  * This puts a much tighter budget on CPU, memory, latency, and throughput requirements than traditional Istio sidecars.

Ztunnel was not designed to be a feature-rich data plane.

The operator code uses the new Helm charts in the [istio/manifests/charts](../manifests/charts/istio-operator). It is not
compatible with the older charts in [istio/istio](https://github.com/istio/istio/tree/1.4.7/install/kubernetes/helm).
See `istio/manifests/charts` for details about the new charts and why they were created. Briefly, the new charts
are intended to support production ready deployments of Istio that follow best practices like canarying for upgrade.

## Código Asíncrono

El código asíncrono sólo significa que el lenguaje 💬 tiene una manera de decirle al sistema / programa 🤖 que, en algún momento del código, 🤖 tendrá que esperar a que *algo más* termine en otro sitio. Digamos que ese *algo más* se llama, por ejemplo, "archivo lento" 📝.

Durante ese tiempo, el sistema puede hacer otras cosas, mientras "archivo lento" 📝 termina.
