1. By installing a separate, very basic "CNI plugin" binary onto the node to forward low-level pod lifecycle events (CmdAdd/CmdDel/etc) from whatever node-level CNI subsystem is in use to this node agent for processing via socket.
1. By running as a node-level daemonset that:

- listens for these UDS events from the CNI plugin (which fire when new pods are spawned in an ambient-enabled namespace), and adds those pods to the ambient mesh.

  //
  // IfHealthyBudget policy means that running pods (status.phase="Running"),
  // but not yet healthy can be evicted only if the guarded application is not
  // disrupted (status.currentHealthy is at least equal to status.desiredHealthy).
  // Healthy pods will be subject to the PDB for eviction.
  //
  // AlwaysAllow policy means that all running pods (status.phase="Running"),

of the conventional `istio-injected: true`. The name of the environment is defined as the namespace
where the corresponding control plane components (config, discovery, auto-injection) are running.
In the examples below, by default this is the `istio-control` namespace. Pod annotations can also
be used to select a different 'environment'.

## Installing

  // Valid values are:
  //
  // - "Allow" (default): allows CronJobs to run concurrently;
  // - "Forbid": forbids concurrent runs, skipping next run if previous run hasn't finished yet;
  // - "Replace": cancels currently running job and replaces it with a new one
  // +optional
  optional string concurrencyPolicy = 3;

  // This flag tells the controller to suspend subsequent executions, it does

```

This installs the controller into the cluster in the istio-operator namespace. The controller in turns installs
the Istio control plane into the istio-system namespace by default.

### Controller (running locally)

1. Set env $WATCH_NAMESPACE (default value is "istio-system") and $LEADER_ELECTION_NAMESPACE (default value is "istio-operator")

When fetching certificates, ztunnel will authenticate to the CA with its own identity, but request the identity of another workload.
Critically, the CA must enforce that the ztunnel has permission to request that identity.
Requests for identities not running on the node are rejected.
