# Helm Profiles

This folder provides a variety of "profiles" for helm installation.
While a user can just explicitly pass this with `--values/-f`.

However, Istio also provides a feature to bundle these with the charts, which is convenient when installing from remote charts.
For details, see `copy-templates` Makefile target, and `manifests/zzz_profile.yaml`.

Any changes to this folder should have a `make copy-templates` applied afterwards.

// This is a sample chained plugin that supports multiple CNI versions. It
// parses prevResult according to the cniVersion
package plugin

import "errors"

// ErrNotImplemented is returned when a requested feature is not implemented.
var ErrNotImplemented = errors.New("not implemented")

// Program defines a method which programs iptables based on the parameters
// provided in Redirect.

  // Absolute number is calculated from percentage by rounding up. This can not be 0.
  // Defaults to 1. This field is alpha-level and is only honored by servers that enable the
  // MaxUnavailableStatefulSet feature. The field applies to all pods in the range 0 to
  // Replicas-1. That means if there is any unavailable pod in the range 0 to Replicas-1, it
  // will be counted towards MaxUnavailable.

  * 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.
Quite the opposite - an *aggressively* small feature set is the key feature that makes ztunnel viable.
It very intentionally does not offer L7 (HTTP) functionality, for instance, which would likely violate some of the goals above, without contributing to them.
