## Ambient mode details

Fundamentally, this component is responsible for the following:

      # minAvailable: 1

    # A minimal set of requested resources to applied to all deployments so that
    # Horizontal Pod Autoscaler will be able to function (if set).
    # Each component can overwrite these default values by adding its own resources
    # block in the relevant section below and setting the desired resources values.
    defaultResources:
      requests:

				log.Debugf("ignoring error deleting optional iptables rule: %v", err)
			}
		}
	}
	return errors.Join(delErrs...)
}

// Setup iptables rules for in-pod mode. Ideally this should be an idempotent function.
// NOTE that this expects to be run from within the pod network namespace!
func (cfg *IptablesConfigurator) CreateInpodRules(hostProbeSNAT *netip.Addr) error {
	// Append our rules here

  // and appends those labels to the pod template.  When true,
  // the user is responsible for picking unique labels and specifying
  // the selector.  Failure to pick a unique label may cause this
  // and other jobs to not function correctly.  However, You may see
  // `manualSelector=true` in jobs that were created with the old `extensions/v1beta1`
  // API.

// sleepWatchInstall blocks until any file change for the binaries or config are detected.
// At that point, the func yields so the caller can recheck the validity of the install.
// If an error occurs or context is canceled, the function will return an error.
func (in *Installer) sleepWatchInstall(ctx context.Context, installedBinFiles sets.String) error {
	// Watch our specific binaries, in each configured binary dir.

Because Ztunnel can have Istio semantics baked in, we do not need to encode all this information on the wire.
Instead, an Istio specific field like `ExpectedTLSIdentity: spiffe://foo.bar` can encode the same information, at a fraction of the cost.

In our testing, even the most generous representations give custom types a 10x edge (in size, allocations, and CPU time) over Envoy types.
