The Istio CNI Node Agent is responsible for several things

- Install an Istio CNI plugin binary on each node's filesystem, updating that node's CNI config in e.g (`/etc/cni/net.d`), and watching the config and binary paths to reinstall if things are modified.

## Traffic routing

Based on the three [redirection](#redirection) paths, the ztunnel has three primary types of traffic it handles.

### Outbound

Requests leaving a pod go through the "outbound" code path on port 15001.
This is where most of Ztunnel's logic lives.

export GOSUMDB ?= sum.golang.org

# If GOPATH is not set by the env, set it to a sane value
GOPATH ?= $(shell cd ${ISTIO_GO}/../../..; pwd)
export GOPATH

# If GOPATH is made up of several paths, use the first one for our targets in this Makefile
GO_TOP := $(shell echo ${GOPATH} | cut -d ':' -f1)
export GO_TOP

GO ?= go

GOARCH_LOCAL := $(TARGET_ARCH)
GOOS_LOCAL := $(TARGET_OS)

  // Path is matched against the path of an incoming request. Currently it can
  // contain characters disallowed from the conventional "path" part of a URL
  // as defined by RFC 3986. Paths must begin with a '/'. When unspecified,
  // all paths from incoming requests are matched.

  optional string path = 1;

  // PathType determines the interpretation of the Path matching. PathType can

  // that all host paths may be used.

refer to the Go struct path schema and hence have names with a capitalized first letter.
The Helm values.yaml API is validated in
[validate_values.go](pkg/validate/validate_values.go)
and refer to the values.yaml data paths. Hence, these rules have names with a lower case first letter.
Apart from validating the correctness of individual fields, the operator ensure that relationships between values in
